Question 1

Chen gathered sources: news said a tsunami reached shore in 20 minutes; book said earthquakes shake up to 2 minutes; eyewitness said a sinkhole opened in 10 seconds. According to the information, which statement is supported?

  1. Tsunamis can reach shore in minutes after a quake (correct answer)
  2. Earthquakes always take hours before shaking starts
  3. Sinkholes need many years to open once they start
  4. Tsunamis move slowly and take weeks to arrive
Explanation: This question tests 2nd grade ability to gather information from sources about fast Earth events (NGSS 2-ESS1-1: Use information from several sources to provide evidence that Earth events can occur quickly or slowly). Earth events that happen quickly occur in seconds, minutes, hours, or days—time periods we can observe or measure. Fast Earth events include: earthquakes (ground shakes for 30 seconds to 2 minutes, causes sudden changes), volcanic eruptions (lava and ash shoot out in hours, flows down in hours to days), landslides (rocks and soil slide in seconds to minutes), floods (water rises and covers land in hours after rain), tornadoes (form and destroy in minutes, move quickly), avalanches (snow slides in seconds), lightning strikes (happens in split second, starts fires immediately), tsunamis (waves reach shore in minutes to hours), and sinkholes (ground collapses suddenly). These events change Earth's surface quickly—fast enough that we can see the entire event happen or see the before-and-after in a short time. This is different from slow Earth events like mountains forming or canyons eroding, which take thousands or millions of years. In this scenario, the sources include news, a book, and an eyewitness account. The information shows tsunamis reach shore in 20 minutes, earthquakes shake up to 2 minutes, and sinkholes open in 10 seconds. Choice A is correct because it accurately states that tsunamis can reach shore in minutes after a quake, supported by the news and book sources. Choice C represents a misconception about time scales, which happens when students incorrectly apply slow durations like many years to fast events such as sinkholes. To help students gather information about fast Earth events: Explicitly teach time scales: 'Fast events: seconds, minutes, hours, days. Slow events: years, thousands of years, millions of years.' Practice identifying sources: 'This came from the book. This came from the video. Both sources help us learn.' Create a 'Fast Earth Events' chart with columns for Event, How Fast, Source, What Happens. Have students find information from different sources and record time information. Use video clips showing fast events (earthquake shaking, landslide occurring) to make time scales concrete. Compare: 'Earthquake lasts less than 2 minutes. Mountains grow over millions of years. Which is fast?' Emphasize gathering from multiple sources: 'The book told us. The news article also said. The video showed. All these sources give evidence.' Watch for students who can't distinguish fast from slow time scales, who don't cite sources, or who include weather events (not Earth events). Practice: 'Is this fast enough to watch happen? If yes, probably a fast Earth event.'

Question 2

Maya used sources: book says earthquakes shake 30 seconds–2 minutes; video shows landslide in 40 seconds; news reports flood rose in 6 hours. Based on the sources, which events happen quickly?

  1. Earthquake seconds–minutes, landslide seconds, flood hours (correct answer)
  2. Mountains grow in minutes, rivers form in hours
  3. Earthquake lasts many years, slowly cracking buildings
  4. Landslides happen, but the sources give no time
Explanation: This question tests 2nd grade ability to gather information from sources about fast Earth events (NGSS 2-ESS1-1: Use information from several sources to provide evidence that Earth events can occur quickly or slowly). Earth events that happen quickly occur in seconds, minutes, hours, or days—time periods we can observe or measure. Fast Earth events include: earthquakes (ground shakes for 30 seconds to 2 minutes, causes sudden changes), volcanic eruptions (lava and ash shoot out in hours, flows down in hours to days), landslides (rocks and soil slide in seconds to minutes), floods (water rises and covers land in hours after rain), tornadoes (form and destroy in minutes, move quickly), avalanches (snow slides in seconds), lightning strikes (happens in split second, starts fires immediately), tsunamis (waves reach shore in minutes to hours), and sinkholes (ground collapses suddenly). These events change Earth's surface quickly—fast enough that we can see the entire event happen or see the before-and-after in a short time. This is different from slow Earth events like mountains forming or canyons eroding, which take thousands or millions of years. In this scenario, the sources include a book, a video, and a news report. The information shows earthquakes shake for 30 seconds to 2 minutes, landslides occur in 40 seconds, and floods rise in 6 hours. Choice A is correct because it accurately identifies fast Earth events like earthquakes, landslides, and floods with their quick time scales, supported by the book, video, and news report sources. Choice B represents a misconception about time scales, which happens when students confuse fast events with slow ones like mountain growth or river formation that actually take thousands or millions of years. To help students gather information about fast Earth events: Explicitly teach time scales: 'Fast events: seconds, minutes, hours, days. Slow events: years, thousands of years, millions of years.' Practice identifying sources: 'This came from the book. This came from the video. Both sources help us learn.' Create a 'Fast Earth Events' chart with columns for Event, How Fast, Source, What Happens. Have students find information from different sources and record time information. Use video clips showing fast events (earthquake shaking, landslide occurring) to make time scales concrete. Compare: 'Earthquake lasts less than 2 minutes. Mountains grow over millions of years.

If yes, probably a fast Earth event.'

Question 3

Chen watched a video called "Landslide in Action," 1 minute long. He read a book saying landslides can slide in seconds. An eyewitness said, "In 20 seconds, rocks covered the road." Based on the sources, which statement is supported?

  1. Landslides can move rocks downhill in seconds. (correct answer)
  2. Landslides happen slowly, taking many years each time.
  3. Landslides are only made of water, not rocks.
  4. Landslides always give a week of warning first.
Explanation: This question tests 2nd grade ability to gather information from sources about fast Earth events (NGSS 2-ESS1-1: Use information from several sources to provide evidence that Earth events can occur quickly or slowly).

These events change Earth's surface quickly—fast enough that we can see the entire event happen or see the before-and-after in a short time. This is different from slow Earth events like mountains forming or canyons eroding, which take thousands or millions of years. In this scenario, the sources include a video, a book, and an eyewitness account. The information shows landslides slide in seconds, a 1-minute video of action, and rocks covering a road in 20 seconds. Choice A is correct because it correctly describes landslides as moving rocks downhill in seconds, which matches the video, book, and eyewitness sources. Choice B represents a misconception about time scales, which happens when students confuse fast events like landslides with slow processes taking many years. To help students gather information about fast Earth events: Explicitly teach time scales: 'Fast events: seconds, minutes, hours, days. Slow events: years, thousands of years, millions of years.' Practice identifying sources: 'This came from the book. This came from the video. Both sources help us learn.'

These events change Earth's surface quickly—fast enough that we can see the entire event happen or see the before-and-after in a short time. This is different from slow Earth events like mountains forming or canyons eroding, which take thousands or millions of years. In this scenario, the sources include a scientist's statement, a news report, and a photo series. The information shows earthquakes shake for 30 seconds to 2 minutes, a quake lasts 60 seconds, and walls crack quickly. Choice A is correct because it correctly states that earthquakes can shake the ground for seconds to minutes, which is supported by the scientist, news report, and photo series. Choice B represents an error in time scales, which happens when students state incorrect durations like many days instead of short times provided by sources. To help students gather information about fast Earth events: Explicitly teach time scales: 'Fast events: seconds, minutes, hours, days. Slow events: years, thousands of years, millions of years.'

Yuki used sources: video showed an avalanche rushing down in 30 seconds; book said lightning strikes in a split second; news said a sinkhole opened in 2 minutes. According to the information gathered, which event is fastest?

  1. Lightning strike, in a split second (correct answer)
  2. Avalanche, in 30 seconds
  3. Sinkhole, in 2 minutes
  4. All three take days to happen
Explanation: This question tests 2nd grade ability to gather information from sources about fast Earth events (NGSS 2-ESS1-1: Use information from several sources to provide evidence that Earth events can occur quickly or slowly). Earth events that happen quickly occur in seconds, minutes, hours, or days—time periods we can observe or measure. Fast Earth events include: earthquakes (ground shakes for 30 seconds to 2 minutes, causes sudden changes), volcanic eruptions (lava and ash shoot out in hours, flows down in hours to days), landslides (rocks and soil slide in seconds to minutes), floods (water rises and covers land in hours after rain), tornadoes (form and destroy in minutes, move quickly), avalanches (snow slides in seconds), lightning strikes (happens in split second, starts fires immediately), tsunamis (waves reach shore in minutes to hours), and sinkholes (ground collapses suddenly). These events change Earth's surface quickly—fast enough that we can see the entire event happen or see the before-and-after in a short time. This is different from slow Earth events like mountains forming or canyons eroding, which take thousands or millions of years. In this scenario, the sources include a video, a book, and news. The information shows avalanches rush down in 30 seconds, lightning strikes in a split second, and sinkholes open in 2 minutes. Choice A is correct because it identifies lightning strike in a split second as the fastest, which matches the book's description of the quickest time scale among the events. Choice D represents a misconception about time scales, which happens when students incorrectly group fast events as taking days instead of seconds or minutes. To help students gather information about fast Earth events: Explicitly teach time scales: 'Fast events: seconds, minutes, hours, days. Slow events: years, thousands of years, millions of years.' Practice identifying sources: 'This came from the book. This came from the video. Both sources help us learn.' Create a 'Fast Earth Events' chart with columns for Event, How Fast, Source, What Happens. Have students find information from different sources and record time information. Use video clips showing fast events (earthquake shaking, landslide occurring) to make time scales concrete. Compare: 'Earthquake lasts less than 2 minutes. Mountains grow over millions of years. Which is fast?' Emphasize gathering from multiple sources: 'The book told us. The news article also said. The video showed. All these sources give evidence.' Watch for students who can't distinguish fast from slow time scales, who don't cite sources, or who include weather events (not Earth events). Practice: 'Is this fast enough to watch happen? If yes, probably a fast Earth event.'

Question 13

Maya gathered sources: a news report said an earthquake shook 45 seconds, a book said landslides race downhill in minutes, and a video showed a tornado lasting 12 minutes. Based on the sources, which events happen quickly?

  1. Mountains grow in millions of years, slowly changing land.
  2. Earthquakes, landslides, and tornadoes happen in seconds or minutes. (correct answer)
  3. Earthquakes take many years, but tornadoes take days.
  4. Rivers cut canyons in minutes after one rainstorm.
Explanation: This question tests 2nd grade ability to gather information from sources about fast Earth events (NGSS 2-ESS1-1: Use information from several sources to provide evidence that Earth events can occur quickly or slowly). Earth events that happen quickly occur in seconds, minutes, hours, or days—time periods we can observe or measure. Fast Earth events include: earthquakes (ground shakes for 30 seconds to 2 minutes, causes sudden changes), volcanic eruptions (lava and ash shoot out in hours, flows down in hours to days), landslides (rocks and soil slide in seconds to minutes), floods (water rises and covers land in hours after rain), tornadoes (form and destroy in minutes, move quickly), avalanches (snow slides in seconds), lightning strikes (happens in split second, starts fires immediately), tsunamis (waves reach shore in minutes to hours), and sinkholes (ground collapses suddenly). These events change Earth's surface quickly—fast enough that we can see the entire event happen or see the before-and-after in a short time. This is different from slow Earth events like mountains forming or canyons eroding, which take thousands or millions of years. In this scenario, the sources include a news report, a book, and a video. The information shows earthquakes last 45 seconds, landslides race downhill in minutes, and tornadoes last 12 minutes. Choice B is correct because it accurately identifies earthquakes, landslides, and tornadoes as happening in seconds or minutes, which is supported by the news report, book, and video sources. Choice A represents a misconception about time scales, which happens when students confuse slow events like mountain growth over millions of years with fast events. To help students gather information about fast Earth events: Explicitly teach time scales: 'Fast events: seconds, minutes, hours, days. Slow events: years, thousands of years, millions of years.' Practice identifying sources: 'This came from the book. This came from the video. Both sources help us learn.'

If yes, probably a fast Earth event.'

Question 14

Maya used sources; what evidence shows these Earth events happen quickly?

  1. Mountains grow in minutes, according to a book.
  2. Earthquakes shake seconds to minutes, sources report. (correct answer)
  3. Canyons form in hours, the news reports.
  4. All Earth events take the same time, sources show.
Explanation: This question tests 2nd grade ability to gather information from sources about fast Earth events (NGSS 2-ESS1-1: Use information from several sources to provide evidence that Earth events can occur quickly or slowly). Earth events that happen quickly occur in seconds, minutes, hours, or days—time periods we can observe or measure. Fast Earth events include: earthquakes (ground shakes for 30 seconds to 2 minutes, causes sudden changes), volcanic eruptions (lava and ash shoot out in hours, flows down in hours to days), landslides (rocks and soil slide in seconds to minutes), floods (water rises and covers land in hours after rain), tornadoes (form and destroy in minutes, move quickly), avalanches (snow slides in seconds), lightning strikes (happens in split second, starts fires immediately), tsunamis (waves reach shore in minutes to hours), and sinkholes (ground collapses suddenly). In this scenario, Maya used sources (like a book, news reports, or other materials) to gather evidence about how quickly Earth events happen. Choice B is correct because it accurately states that earthquakes shake for seconds to minutes according to sources, which matches the scientific fact that earthquakes typically last 30 seconds to 2 minutes—a fast Earth event we can observe happening. Choice A represents a common misconception where students confuse fast and slow events—mountains actually grow over millions of years through slow processes, not in minutes. To help students gather information about fast Earth events: Explicitly teach time scales: 'Fast events: seconds, minutes, hours, days. Slow events: years, thousands of years, millions of years.' Practice identifying sources: 'This came from the book. This came from the video. Both sources help us learn.' Create a 'Fast Earth Events' chart with columns for Event, How Fast, Source, What Happens.

Question 15

Based on sources, what evidence shows a flood can happen quickly?

  1. Water rises in hours and covers land fast. (correct answer)
  2. Flood water rises over millions of years.
  3. Floods are always slow because rivers never change.
  4. Floods happen, but sources give no time at all.
Explanation: This question tests 2nd grade ability to gather information from sources about fast Earth events (NGSS 2-ESS1-1: Use information from several sources to provide evidence that Earth events can occur quickly or slowly). Earth events that happen quickly occur in seconds, minutes, hours, or days—time periods we can observe or measure. Fast Earth events include: earthquakes (ground shakes for 30 seconds to 2 minutes, causes sudden changes), volcanic eruptions (lava and ash shoot out in hours, flows down in hours to days), landslides (rocks and soil slide in seconds to minutes), floods (water rises and covers land in hours after rain), tornadoes (form and destroy in minutes, move quickly), avalanches (snow slides in seconds), lightning strikes (happens in split second, starts fires immediately), tsunamis (waves reach shore in minutes to hours), and sinkholes (ground collapses suddenly). In this scenario, the sources provide evidence about floods, specifically how quickly water can rise and cover land during flood events. Choice A is correct because it accurately describes floods as fast Earth events where water rises in hours and covers land fast—this matches observations of flash floods and river floods that can develop within hours after heavy rainfall, making them observable fast Earth events. Choice B represents a misconception about time scales, incorrectly stating flood water rises over millions of years when floods actually occur within hours to days, especially after heavy rain or dam breaks. To help students gather information about fast Earth events: Practice identifying sources: 'This came from the book. This came from the video. Both sources help us learn.' Create a 'Fast Earth Events' chart and have students record: 'Floods - Hours - News report - Water rises and covers land.' Compare: 'Flood happens in hours after rain. Canyon forms over millions of years. Which is fast?'

Question 16

Keisha gathered sources; which statement best shows quick Earth changes?

  1. Lightning strikes in a split second and starts fire. (correct answer)
  2. Lightning slowly builds mountains over many years.
  3. Lightning makes rivers rise for millions of years.
  4. Lightning is not an Earth event, sources report.
Explanation: This question tests 2nd grade ability to gather information from sources about fast Earth events (NGSS 2-ESS1-1: Use information from several sources to provide evidence that Earth events can occur quickly or slowly). Earth events that happen quickly occur in seconds, minutes, hours, or days—time periods we can observe or measure. Fast Earth events include: earthquakes (ground shakes for 30 seconds to 2 minutes, causes sudden changes), volcanic eruptions (lava and ash shoot out in hours, flows down in hours to days), landslides (rocks and soil slide in seconds to minutes), floods (water rises and covers land in hours after rain), tornadoes (form and destroy in minutes, move quickly), avalanches (snow slides in seconds), lightning strikes (happens in split second, starts fires immediately), tsunamis (waves reach shore in minutes to hours), and sinkholes (ground collapses suddenly). In this scenario, Keisha gathered sources about Earth events, specifically looking for evidence of quick Earth changes including lightning strikes. Choice A is correct because it accurately describes lightning as a fast Earth event that strikes in a split second and can start fires—this is scientifically accurate as lightning occurs in fractions of a second and can immediately ignite fires, causing rapid changes to Earth's surface through burning. Choice B represents a misconception, incorrectly claiming lightning slowly builds mountains over years when lightning is actually an instantaneous event, and mountain building is a slow geological process taking millions of years. To help students gather information about fast Earth events: Explicitly teach time scales: 'Lightning happens in less than one second—faster than you can blink!' Use slow-motion videos to show how fast lightning really is. Emphasize that lightning can cause immediate changes by starting fires that quickly change the land.

Question 17

Jamal read sources; which statement is supported about earthquakes?

  1. Earthquakes shake for seconds, cracking roads quickly. (correct answer)
  2. Earthquakes take years, so no sudden change happens.
  3. Earthquakes are slow winds that spin for hours.
  4. Earthquakes only happen on the Moon, sources say.
Explanation: This question tests 2nd grade ability to gather information from sources about fast Earth events (NGSS 2-ESS1-1: Use information from several sources to provide evidence that Earth events can occur quickly or slowly). Earth events that happen quickly occur in seconds, minutes, hours, or days—time periods we can observe or measure. Fast Earth events include: earthquakes (ground shakes for 30 seconds to 2 minutes, causes sudden changes), volcanic eruptions (lava and ash shoot out in hours, flows down in hours to days), landslides (rocks and soil slide in seconds to minutes), floods (water rises and covers land in hours after rain), tornadoes (form and destroy in minutes, move quickly), avalanches (snow slides in seconds), lightning strikes (happens in split second, starts fires immediately), tsunamis (waves reach shore in minutes to hours), and sinkholes (ground collapses suddenly). In this scenario, Jamal read sources (such as science articles, earthquake reports, or educational materials) that provide evidence about earthquakes and their characteristics. Choice A is correct because it accurately describes earthquakes as fast Earth events that shake for seconds (typically 30 seconds to 2 minutes) and can crack roads quickly, showing immediate, observable changes to Earth's surface—this is supported by scientific observations and earthquake monitoring data. Choice B represents a misconception about time scales, incorrectly claiming earthquakes take years when they actually occur in seconds to minutes, making them fast Earth events that cause sudden changes. To help students gather information about fast Earth events: Explicitly teach time scales: 'Fast events: seconds, minutes, hours, days. Slow events: years, thousands of years, millions of years.' Use video clips showing earthquake shaking and damage to make time scales concrete. Emphasize gathering from multiple sources: 'The book told us. The news article also said. The video showed. All these sources give evidence.'

Question 18

Based on the sources, what is true about a volcanic eruption?

  1. Lava and ash can shoot out in minutes to hours. (correct answer)
  2. Volcanic eruptions always take millions of years.
  3. Volcanic eruptions are quiet snow slides in seconds.
  4. Volcanoes never change land, even after eruptions.
Explanation: This question tests 2nd grade ability to gather information from sources about fast Earth events (NGSS 2-ESS1-1: Use information from several sources to provide evidence that Earth events can occur quickly or slowly). Earth events that happen quickly occur in seconds, minutes, hours, or days—time periods we can observe or measure. Fast Earth events include: earthquakes (ground shakes for 30 seconds to 2 minutes, causes sudden changes), volcanic eruptions (lava and ash shoot out in hours, flows down in hours to days), landslides (rocks and soil slide in seconds to minutes), floods (water rises and covers land in hours after rain), tornadoes (form and destroy in minutes, move quickly), avalanches (snow slides in seconds), lightning strikes (happens in split second, starts fires immediately), tsunamis (waves reach shore in minutes to hours), and sinkholes (ground collapses suddenly). In this scenario, the sources provide information about volcanic eruptions, including how quickly lava and ash can emerge during an eruption. Choice A is correct because it accurately describes volcanic eruptions as fast Earth events where lava and ash can shoot out in minutes to hours—this matches scientific observations that explosive eruptions can begin suddenly with ash and lava ejected within minutes to hours, making them observable fast Earth events. Choice B represents a misconception about time scales, incorrectly claiming volcanic eruptions always take millions of years when the actual eruption event (lava and ash shooting out) happens in minutes to hours, though volcano formation itself may take longer. To help students gather information about fast Earth events: Use video clips showing volcanic eruptions to make time scales concrete. Create a chart: 'Volcanic eruption - Minutes to hours - Video/book - Lava and ash shoot out.' Watch for students who confuse the fast eruption event with the slow process of volcano formation over time.

Question 19

According to the sources, how fast can a landslide happen?

  1. In seconds to minutes, rocks and soil slide fast. (correct answer)
  2. In millions of years, rocks slide down slowly.
  3. In one month, soil floats up into clouds.
  4. Landslides happen, but time is never measured.
Explanation: This question tests 2nd grade ability to gather information from sources about fast Earth events (NGSS 2-ESS1-1: Use information from several sources to provide evidence that Earth events can occur quickly or slowly). Earth events that happen quickly occur in seconds, minutes, hours, or days—time periods we can observe or measure. Fast Earth events include: earthquakes (ground shakes for 30 seconds to 2 minutes, causes sudden changes), volcanic eruptions (lava and ash shoot out in hours, flows down in hours to days), landslides (rocks and soil slide in seconds to minutes), floods (water rises and covers land in hours after rain), tornadoes (form and destroy in minutes, move quickly), avalanches (snow slides in seconds), lightning strikes (happens in split second, starts fires immediately), tsunamis (waves reach shore in minutes to hours), and sinkholes (ground collapses suddenly). In this scenario, the sources provide specific information about landslides, including how fast they can occur when rocks and soil slide down a slope. Choice A is correct because it accurately states that landslides happen in seconds to minutes with rocks and soil sliding fast—this matches scientific observations that landslides are rapid mass movements of earth materials that can occur within seconds to minutes, especially after triggers like heavy rain or earthquakes. Choice B represents a misconception about time scales, incorrectly stating landslides take millions of years when they are actually sudden, fast events that we can observe happening. To help students gather information about fast Earth events: Create a 'Fast Earth Events' chart with columns for Event, How Fast, Source, What Happens. Have students find information from different sources and record time information. Watch for students who can't distinguish fast from slow time scales or who don't cite sources. Practice: 'Is this fast enough to watch happen? If yes, probably a fast Earth event.'

Question 20

Sofia used sources; which fast event can start with an underwater earthquake?

  1. A tsunami reaches shore in minutes to hours. (correct answer)
  2. A canyon forms in minutes from ocean waves.
  3. A mountain grows taller in one day, sources say.
  4. A rainbow forms because rocks slide downhill.
Explanation: This question tests 2nd grade ability to gather information from sources about fast Earth events (NGSS 2-ESS1-1: Use information from several sources to provide evidence that Earth events can occur quickly or slowly). Earth events that happen quickly occur in seconds, minutes, hours, or days—time periods we can observe or measure. Fast Earth events include: earthquakes (ground shakes for 30 seconds to 2 minutes, causes sudden changes), volcanic eruptions (lava and ash shoot out in hours, flows down in hours to days), landslides (rocks and soil slide in seconds to minutes), floods (water rises and covers land in hours after rain), tornadoes (form and destroy in minutes, move quickly), avalanches (snow slides in seconds), lightning strikes (happens in split second, starts fires immediately), tsunamis (waves reach shore in minutes to hours), and sinkholes (ground collapses suddenly). In this scenario, Sofia used sources to learn about fast events that can start with underwater earthquakes, focusing on the connection between underwater earthquakes and resulting fast Earth events. Choice A is correct because it accurately identifies tsunamis as fast Earth events that reach shore in minutes to hours after being triggered by underwater earthquakes—this is scientifically accurate as tsunamis are fast-moving ocean waves caused by underwater earthquakes that can reach coastlines within minutes to hours. Choice B represents a misconception, incorrectly claiming canyons form in minutes from ocean waves when canyon formation is actually a slow process taking millions of years through erosion. To help students gather information about fast Earth events: Teach cause and effect: 'Underwater earthquake happens first. Then tsunami waves travel fast. Waves reach shore in minutes to hours.' Use diagrams showing the sequence of events. Emphasize gathering from multiple sources to understand connections between events.
