Question 1

Trees photosynthesize (biosphere); how does this action cause an effect in the atmosphere?

  1. Photosynthesis (biosphere) results in more carbon dioxide in the atmosphere.
  2. Photosynthesis (biosphere) results in less carbon dioxide in the atmosphere. (correct answer)
  3. The atmosphere results in trees (biosphere) turning into rocks in days.
  4. Trees (biosphere) and air (atmosphere) exist together without any effects.
Explanation: This question tests students' ability to describe cause-and-effect relationships among Earth systems using specific examples (NGSS 5-ESS2-1). Cause-and-effect relationships describe how one event (the cause) leads to another event (the effect). In Earth systems, when one system acts or changes, it often causes changes in other systems. For example: when plants photosynthesize, they take in carbon dioxide and release oxygen; when forests are cut down, less CO2 is removed from the air; when ocean algae bloom, they can significantly change atmospheric gas levels. Understanding these cause-effect relationships helps explain many Earth processes and changes we observe. Choice B is correct because it accurately identifies the cause (trees performing photosynthesis in the biosphere) and the effect (reduction of carbon dioxide in the atmosphere), showing clear causal relationship between systems. This demonstrates understanding that during photosynthesis, plants absorb CO2 from the air to make glucose, thereby decreasing atmospheric CO2 levels. Choice A is incorrect because it states the opposite effect - photosynthesis removes CO2 rather than adding it. This error commonly occurs when students confuse photosynthesis with respiration or don't understand the direction of gas exchange. Choice C suggests an impossible transformation of trees into rocks in days, showing confusion about realistic timescales and processes. To help students: Use explicit cause-effect graphic organizers with boxes and arrows: CAUSE (trees photosynthesize) → EFFECT (CO2 decreases in air). Practice with clear examples first: burning wood → CO2 increases; algae bloom → oxygen increases. Use temporal language to reinforce causation: When trees photosynthesize, it causes carbon dioxide to be removed from the atmosphere. Create diagrams showing CO2 entering leaves and O2 exiting. Act out cause-effect: students represent CO2 molecules being 'captured' by a tree. Use sentence frames: 'When trees in the biosphere photosynthesize, it causes the atmosphere to have less carbon dioxide.' Emphasize the equation: CO2 + water + sunlight → glucose + oxygen. Watch for: students who confuse photosynthesis with respiration, who reverse the gases involved, who think plants only produce CO2, or who don't understand that removing a gas means decreasing its concentration.

Question 2

When the Colorado River (hydrosphere) flows for years, it erodes rock (geosphere). What is the cause-and-effect relationship?

  1. Geosphere erosion causes the hydrosphere to start flowing faster
  2. Hydrosphere flow causes the geosphere to erode and form a canyon (correct answer)
  3. Atmosphere wind causes the geosphere to erode and form a canyon
  4. Hydrosphere flow and geosphere erosion happen together with no cause
Explanation: This question tests students' ability to describe cause-and-effect relationships among Earth systems using specific examples (NGSS 5-ESS2-1). Cause-and-effect relationships describe how one event (the cause) leads to another event (the effect). In Earth systems, when one system acts or changes, it often causes changes in other systems. For example: when a river (hydrosphere) flows over rocks for many years, it erodes the rock and shapes the land (effect on geosphere); when there's no rain for months (atmosphere/hydrosphere), plants cannot get water they need and die (effect on biosphere); when trees (biosphere) perform photosynthesis, they remove CO2 from and add oxygen to the air (effect on atmosphere). Understanding these cause-effect relationships helps explain many Earth processes and changes we observe. Choice B is correct because it accurately identifies the cause as hydrosphere flow and the effect as geosphere erosion forming a canyon, showing a clear causal relationship between systems. This demonstrates understanding that one system's action can cause changes in another system, and that we can trace these relationships in real-world examples. Choice A is incorrect because it reverses cause and effect, naming geosphere erosion as the cause instead of the effect. This error commonly occurs when students can identify that two systems are involved but don't correctly determine which is acting (cause) and which is being changed (effect), or when they confuse sequence (A happens then B happens) with causation (A causes B to happen). Some students may also describe both as effects of a third cause, or may not recognize the directional nature of cause-effect relationships. To help students: Use explicit cause-effect graphic organizers with boxes and arrows: CAUSE (system + action) → EFFECT (system + change). Practice with clear examples first: volcanic eruption (geosphere) → ash in air (atmosphere). Use temporal language to reinforce causation: When [cause happens], it causes [effect]. Create before/after comparisons showing the change. Act out cause-effect: one student represents cause system acting, another represents effect system changing. Use sentence frames: 'When the [system] [acts by doing X], it causes the [system] to [change in Y way].' Emphasize that cause comes first in time, effect follows. Watch for: students who reverse cause and effect, who identify systems involved but not which causes change in the other, who confuse coincidence with causation, or who can't distinguish the acting system from the system being acted upon. Have students draw arrows from cause to effect to reinforce directionality.

Question 3

How does a landslide (geosphere) entering a river cause an effect in the hydrosphere?​

  1. River water (hydrosphere) causes the landslide (geosphere) to climb uphill.
  2. A landslide (geosphere) results in muddy river water (hydrosphere). (correct answer)
  3. A landslide (geosphere) results in cleaner river water (hydrosphere).
  4. A landslide (geosphere) and river water (hydrosphere) do not affect each other.
Explanation: This question tests students' ability to describe cause-and-effect relationships among Earth systems using specific examples (NGSS 5-ESS2-1). Cause-and-effect relationships describe how one event (the cause) leads to another event (the effect). In Earth systems, when one system acts or changes, it often causes changes in other systems. For example: when soil erodes into a stream, it makes the water muddy; when volcanic ash falls into lakes, it changes the water chemistry; when glaciers melt, they add fresh water to the ocean. Understanding these cause-effect relationships helps explain many Earth processes and changes we observe. Choice B is correct because it accurately identifies the cause (landslide from the geosphere entering the river) and the effect (muddy water in the hydrosphere), showing clear causal relationship between systems. This demonstrates understanding that when earth materials move into water bodies, they cause the water to become turbid or muddy by adding sediment particles. Choice A is incorrect because it suggests an impossible effect - river water cannot cause a landslide to move uphill against gravity. This error commonly occurs when students reverse cause and effect or create illogical relationships. Choice C incorrectly states the opposite effect - landslides add sediment that makes water muddier, not cleaner. To help students: Use explicit cause-effect graphic organizers with boxes and arrows: CAUSE (landslide enters river) → EFFECT (water becomes muddy). Practice with clear examples first: rain washes soil → stream turns brown. Use temporal language to reinforce causation: When a landslide enters a river, it causes the water to become muddy with sediment. Create before/after comparisons showing clear vs. muddy water. Act out cause-effect: drop soil into clear water to show the immediate effect. Use sentence frames: 'When the landslide enters the river, it causes the water to become muddy and brown.' Emphasize that sediment added to water makes it cloudier, not clearer. Watch for: students who reverse cause and effect, who think all changes must be positive, who confuse the direction of change (cleaner vs. muddier), or who don't understand that adding earth materials to water creates turbidity.

Question 4

A landslide (geosphere) crashes into a river (hydrosphere), making the water muddy. What is the cause-and-effect relationship shown?

  1. Hydrosphere muddy water causes the geosphere hillside to slide
  2. Geosphere landslide results in the hydrosphere river becoming muddy (correct answer)
  3. Atmosphere wind results in the hydrosphere river becoming muddy
  4. Geosphere landslide results in the biosphere trees making more oxygen
Explanation: This question tests students' ability to describe cause-and-effect relationships among Earth systems using specific examples (NGSS 5-ESS2-1). Cause-and-effect relationships describe how one event (the cause) leads to another event (the effect). In Earth systems, when one system acts or changes, it often causes changes in other systems. For example: when a river (hydrosphere) flows over rocks for many years, it erodes the rock and shapes the land (effect on geosphere); when there's no rain for months (atmosphere/hydrosphere), plants cannot get water they need and die (effect on biosphere); when trees (biosphere) perform photosynthesis, they remove CO2 from and add oxygen to the air (effect on atmosphere). Understanding these cause-effect relationships helps explain many Earth processes and changes we observe. Choice B is correct because it accurately identifies the cause as geosphere landslide and the effect as hydrosphere river becoming muddy, showing a clear causal relationship between systems. This demonstrates understanding that one system's action can cause changes in another system, and that we can trace these relationships in real-world examples. Choice A is incorrect because it reverses cause and effect, naming hydrosphere muddy water as the cause instead of the effect. This error commonly occurs when students can identify that two systems are involved but don't correctly determine which is acting (cause) and which is being changed (effect), or when they confuse sequence (A happens then B happens) with causation (A causes B to happen). Some students may also describe both as effects of a third cause, or may not recognize the directional nature of cause-effect relationships. To help students: Use explicit cause-effect graphic organizers with boxes and arrows: CAUSE (system + action) → EFFECT (system + change). Practice with clear examples first: volcanic eruption (geosphere) → ash in air (atmosphere). Use temporal language to reinforce causation: When [cause happens], it causes [effect]. Create before/after comparisons showing the change. Act out cause-effect: one student represents cause system acting, another represents effect system changing. Use sentence frames: 'When the [system] [acts by doing X], it causes the [system] to [change in Y way].' Emphasize that cause comes first in time, effect follows.

Have students draw arrows from cause to effect to reinforce directionality.

Question 5

Strong hurricane winds (atmosphere) knock down trees and nests (biosphere). How does the atmosphere cause an effect on the biosphere?

  1. Biosphere trees cause the atmosphere to create stronger hurricane winds
  2. Atmosphere winds cause the biosphere habitats to be damaged or destroyed (correct answer)
  3. Hydrosphere rain causes the biosphere habitats to be damaged or destroyed
  4. Atmosphere winds cause the geosphere to become a muddy river
Explanation: This question tests students' ability to describe cause-and-effect relationships among Earth systems using specific examples (NGSS 5-ESS2-1). Cause-and-effect relationships describe how one event (the cause) leads to another event (the effect). In Earth systems, when one system acts or changes, it often causes changes in other systems.

Some students may also describe both as effects of a third cause, or may not recognize the directional nature of cause-effect relationships. To help students: Use explicit cause-effect graphic organizers with boxes and arrows: CAUSE (system + action) → EFFECT (system + change). Practice with clear examples first: volcanic eruption (geosphere) → ash in air (atmosphere). Use temporal language to reinforce causation: When [cause happens], it causes [effect].

  1. Hydrosphere river water causes the geosphere hillside to suddenly slide.
  2. Geosphere landslide causes the hydrosphere river water to become muddy. (correct answer)
  3. Atmosphere clouds cause the hydrosphere river water to become muddy instantly.
  4. Geosphere landslide causes the biosphere fish to become rocks in the river.
Explanation: This question tests students' ability to describe cause-and-effect relationships among Earth systems using specific examples (NGSS 5-ESS2-1). Cause-and-effect relationships describe how one event (the cause) leads to another event (the effect). In Earth systems, when one system acts or changes, it often causes changes in other systems.

Watch for: students who reverse cause and effect, who identify systems involved but not which causes change in the other, who confuse coincidence with causation, or who can't distinguish the acting system from the system being acted upon. Have students draw arrows from cause to effect to reinforce directionality.

Question 7

During a drought, the atmosphere has little rain, so the biosphere plants die.

  1. Biosphere plants dying causes the atmosphere to stop making rain.
  2. Atmosphere lack of rain causes biosphere plants to die. (correct answer)
  3. Geosphere rocks cause the biosphere plants to die by blocking sunlight.
  4. Atmosphere drought causes the hydrosphere oceans to disappear overnight.
Explanation: This question tests students' ability to describe cause-and-effect relationships among Earth systems using specific examples (NGSS 5-ESS2-1). Cause-and-effect relationships describe how one event (the cause) leads to another event (the effect). In Earth systems, when one system acts or changes, it often causes changes in other systems.

Have students draw arrows from cause to effect to reinforce directionality.

Question 8

When Mount St. Helens erupts (geosphere), ash in air blocks sunlight, so plants die.

  1. Geosphere eruption causes atmosphere ash, leading to biosphere plants dying. (correct answer)
  2. Biosphere plants dying causes atmosphere ash, leading to a geosphere eruption.
  3. Atmosphere ash causes a geosphere eruption, leading to biosphere plants dying.
  4. Geosphere eruption and biosphere plant death happen together, without cause and effect.
Explanation: This question tests students' ability to describe cause-and-effect relationships among Earth systems using specific examples (NGSS 5-ESS2-1). Cause-and-effect relationships describe how one event (the cause) leads to another event (the effect). In Earth systems, when one system acts or changes, it often causes changes in other systems.

  1. Biosphere plant death causes the atmosphere to stop making clouds
  2. Atmosphere drought results in the biosphere losing plants and animals (correct answer)
  3. Geosphere rocks result in the biosphere losing plants and animals
  4. Atmosphere drought results in the geosphere forming a new mountain
Explanation: This question tests students' ability to describe cause-and-effect relationships among Earth systems using specific examples (NGSS 5-ESS2-1). Cause-and-effect relationships describe how one event (the cause) leads to another event (the effect). In Earth systems, when one system acts or changes, it often causes changes in other systems.

This demonstrates understanding that one system's action can cause changes in another system, and that we can trace these relationships in real-world examples. Choice A is incorrect because it reverses cause and effect, naming biosphere plant death as the cause instead of the effect.

Have students draw arrows from cause to effect to reinforce directionality.

Question 10

Volcanic heat (geosphere) melts snow, so the hydrosphere has more flowing water.

  1. Hydrosphere flowing water causes the geosphere volcano to erupt with heat.
  2. Geosphere volcanic heat causes hydrosphere snow and ice to melt into water. (correct answer)
  3. Biosphere animals cause hydrosphere snow and ice to melt into water.
  4. Geosphere volcanic heat causes the atmosphere to turn into solid ice.
Explanation: This question tests students' ability to describe cause-and-effect relationships among Earth systems using specific examples (NGSS 5-ESS2-1). Cause-and-effect relationships describe how one event (the cause) leads to another event (the effect). In Earth systems, when one system acts or changes, it often causes changes in other systems. For example: when a river (hydrosphere) flows over rocks for many years, it erodes the rock and shapes the land (effect on geosphere); when there's no rain for months (atmosphere/hydrosphere), plants cannot get water they need and die (effect on biosphere); when trees (biosphere) perform photosynthesis, they remove CO2 from and add oxygen to the air (effect on atmosphere). Understanding these cause-effect relationships helps explain many Earth processes and changes we observe.

This demonstrates understanding that one system's action can cause changes in another system, and that we can trace these relationships in real-world examples. Choice A is incorrect because it reverses cause and effect, stating that hydrosphere flowing water causes the geosphere volcano to erupt with heat.

Have students draw arrows from cause to effect to reinforce directionality.

Question 11

Nutrient-rich soil (geosphere) supports plants; what effect results in the biosphere?​

  1. Healthy plants (biosphere) result in soil (geosphere) disappearing completely.
  2. Nutrient-rich soil (geosphere) results in healthier plant growth (biosphere). (correct answer)
  3. Nutrient-rich soil (geosphere) results in less oxygen in the atmosphere.
  4. Soil (geosphere) and plants (biosphere) exist together without cause and effect.
Explanation: This question tests students' ability to describe cause-and-effect relationships among Earth systems using specific examples (NGSS 5-ESS2-1). Cause-and-effect relationships describe how one event (the cause) leads to another event (the effect). In Earth systems, when one system acts or changes, it often causes changes in other systems. For example: when soil contains many nutrients, plants grow larger and healthier; when soil lacks nutrients, plants struggle to grow; when minerals weather from rocks, they enrich nearby soil. Understanding these cause-effect relationships helps explain many Earth processes and changes we observe. Choice B is correct because it accurately identifies the cause (nutrient-rich soil in the geosphere) and the effect (healthier plant growth in the biosphere), showing clear causal relationship between systems. This demonstrates understanding that soil quality directly affects plant health - nutrients like nitrogen, phosphorus, and potassium in soil are absorbed by plant roots and enable vigorous growth. Choice A is incorrect because it suggests soil disappears when plants are healthy, which reverses cause and effect and describes an impossible outcome. This error commonly occurs when students know systems interact but create illogical relationships. Choice C incorrectly connects soil nutrients to atmospheric oxygen, missing the direct effect on plants. To help students: Use explicit cause-effect graphic organizers with boxes and arrows: CAUSE (nutrient-rich soil) → EFFECT (healthy plant growth). Practice with clear examples first: fertilized garden → bigger vegetables; poor soil → stunted plants. Use temporal language to reinforce causation: When soil contains many nutrients, it causes plants to grow larger and healthier. Compare plants grown in rich vs. poor soil. Act out cause-effect: students represent nutrients moving from soil into plant roots. Use sentence frames: 'When the soil in the geosphere is rich in nutrients, it causes plants in the biosphere to grow strong and healthy.' Emphasize that plants absorb nutrients through their roots. Watch for: students who reverse cause and effect, who think healthy plants harm soil, who skip the direct connection to plants, or who don't understand that plants need nutrients from soil to grow well.

Question 12

After a flood, hydrosphere water drops sediment, causing the geosphere floodplain to build up.

  1. Geosphere floodplains build up and cause hydrosphere floods to happen.
  2. Hydrosphere floodwater drops sediment and causes geosphere land to build up. (correct answer)
  3. Atmosphere sunlight drops sediment and causes geosphere land to build up.
  4. Hydrosphere floodwater causes the atmosphere to become solid sediment.
Explanation: This question tests students' ability to describe cause-and-effect relationships among Earth systems using specific examples (NGSS 5-ESS2-1). Cause-and-effect relationships describe how one event (the cause) leads to another event (the effect). In Earth systems, when one system acts or changes, it often causes changes in other systems. For example: when a river (hydrosphere) flows over rocks for many years, it erodes the rock and shapes the land (effect on geosphere); when there's no rain for months (atmosphere/hydrosphere), plants cannot get water they need and die (effect on biosphere); when trees (biosphere) perform photosynthesis, they remove CO2 from and add oxygen to the air (effect on atmosphere). Understanding these cause-effect relationships helps explain many Earth processes and changes we observe. Choice B is correct because it accurately identifies the cause as hydrosphere floodwater dropping sediment and the effect as geosphere land building up in the floodplain, showing a clear causal relationship between systems. This demonstrates understanding that one system's action can cause changes in another system, and that we can trace these relationships in real-world examples. Choice A is incorrect because it reverses cause and effect, stating that geosphere floodplains building up cause hydrosphere floods to happen. This error commonly occurs when students can identify that two systems are involved but don't correctly determine which is acting (cause) and which is being changed (effect), or when they confuse sequence (A happens then B happens) with causation (A causes B to happen). Some students may also describe both as effects of a third cause, or may not recognize the directional nature of cause-effect relationships. To help students: Use explicit cause-effect graphic organizers with boxes and arrows: CAUSE (system + action) → EFFECT (system + change). Practice with clear examples first: volcanic eruption (geosphere) → ash in air (atmosphere). Use temporal language to reinforce causation: When [cause happens], it causes [effect]. Create before/after comparisons showing the change. Act out cause-effect: one student represents cause system acting, another represents effect system changing. Use sentence frames: 'When the [system] [acts by doing X], it causes the [system] to [change in Y way].' Emphasize that cause comes first in time, effect follows. Watch for: students who reverse cause and effect, who identify systems involved but not which causes change in the other, who confuse coincidence with causation, or who can't distinguish the acting system from the system being acted upon. Have students draw arrows from cause to effect to reinforce directionality.

Question 13

A volcano erupts (geosphere), ash fills air (atmosphere), then plants die (biosphere). Which statement shows the cause-effect chain?

  1. Biosphere plant death causes ash to enter the atmosphere from a volcano
  2. Geosphere eruption causes ash in atmosphere, leading to biosphere plants dying (correct answer)
  3. Atmosphere ash causes the geosphere volcano to erupt more
  4. Geosphere eruption and biosphere plant death happen together with no cause
Explanation: This question tests students' ability to describe cause-and-effect relationships among Earth systems using specific examples (NGSS 5-ESS2-1). Cause-and-effect relationships describe how one event (the cause) leads to another event (the effect). In Earth systems, when one system acts or changes, it often causes changes in other systems. For example: when a river (hydrosphere) flows over rocks for many years, it erodes the rock and shapes the land (effect on geosphere); when there's no rain for months (atmosphere/hydrosphere), plants cannot get water they need and die (effect on biosphere); when trees (biosphere) perform photosynthesis, they remove CO2 from and add oxygen to the air (effect on atmosphere). Understanding these cause-effect relationships helps explain many Earth processes and changes we observe. Choice B is correct because it accurately identifies the cause as geosphere eruption causing ash in the atmosphere, leading to the effect of biosphere plants dying, showing a clear causal relationship between systems. This demonstrates understanding that one system's action can cause changes in another system, and that we can trace these relationships in real-world examples. Choice A is incorrect because it reverses cause and effect, naming biosphere plant death as the initial cause instead of the final effect. This error commonly occurs when students can identify that two systems are involved but don't correctly determine which is acting (cause) and which is being changed (effect), or when they confuse sequence (A happens then B happens) with causation (A causes B to happen). Some students may also describe both as effects of a third cause, or may not recognize the directional nature of cause-effect relationships. To help students: Use explicit cause-effect graphic organizers with boxes and arrows: CAUSE (system + action) → EFFECT (system + change). Practice with clear examples first: volcanic eruption (geosphere) → ash in air (atmosphere). Use temporal language to reinforce causation: When [cause happens], it causes [effect]. Create before/after comparisons showing the change. Act out cause-effect: one student represents cause system acting, another represents effect system changing. Use sentence frames: 'When the [system] [acts by doing X], it causes the [system] to [change in Y way].' Emphasize that cause comes first in time, effect follows. Watch for: students who reverse cause and effect, who identify systems involved but not which causes change in the other, who confuse coincidence with causation, or who can't distinguish the acting system from the system being acted upon. Have students draw arrows from cause to effect to reinforce directionality.

Question 14

A hurricane's strong winds (atmosphere) knock down trees, changing habitats in the biosphere.

  1. Biosphere trees falling causes hurricane winds in the atmosphere.
  2. Atmosphere hurricane winds cause biosphere habitats to change. (correct answer)
  3. Hydrosphere ocean water causes biosphere habitats to change without winds.
  4. Atmosphere hurricane winds cause the geosphere to melt into liquid rock.
Explanation: This question tests students' ability to describe cause-and-effect relationships among Earth systems using specific examples (NGSS 5-ESS2-1). Cause-and-effect relationships describe how one event (the cause) leads to another event (the effect). In Earth systems, when one system acts or changes, it often causes changes in other systems.

Understanding these cause-effect relationships helps explain many Earth processes and changes we observe. Choice B is correct because it accurately identifies the cause as hurricane winds in the atmosphere and the effect as changed habitats in the biosphere from knocked-down trees, showing a clear causal relationship between systems. This demonstrates understanding that one system's action can cause changes in another system, and that we can trace these relationships in real-world examples. Choice A is incorrect because it reverses cause and effect, stating that biosphere trees falling causes hurricane winds in the atmosphere.
