Middle School Life Science › Describe the flow of matter and energy in the water cycle
What is the name of the area underground that contains groundwater?
an aquifer
a watershed
a well
a water table
The answer is "an aquifer."
The water cycle, also called the hydrological cycle, describes the flow of water on Earth. Most of Earth’s water exists in the oceans. Some important processes in the water cycle are precipitation, evaporation, condensation, runoff, and sublimation or deposition. Water evaporates from the ocean, condenses in clouds, and rains down (precipitates) back to the Earth, where it is collected in oceans or as runoff in rivers and streams that lead back to the oceans.
Only about 3% of Earth’s water is freshwater, and most of that is frozen in glaciers rather than available to us in lakes, rivers, or groundwater stores. Snow melt is a form of runoff but some snow can return to the atmosphere through a process called sublimation, and back to snow from a gaseous state through deposition.
Where does most of Earth's water exist?
in the oceans
in the atmosphere
as lakes, rivers, or streams
underground
The answer is "in the oceans."

Which of these shows the correct order of processes water will travel through if we begin to follow it as a rain drop?
precipitation, runoff, collection, evaporation, condensation, precipitation
runoff, condensation, precipitation, evaporation, precipitation, collection,
runoff, precipitation, condensation, evaporation, collection,
collection, precipitation, runoff, condensation, evaporation,
The answer is "precipitation, runoff, collection, evaporation, condensation, precipitation."

Where is most of Earth's fresh water?
frozen in glaciers
under ground
in lakes and rivers
made by purifying salt water
The answer is "frozen in glaciers."

What is the most effective way to increase the rate of evaporation of a body of water?
increasing the surface area
decreasing the movement of air over the surface
increasing the volume
decreasing the temperature
The answer is "increasing the surface area" because there is more water being warmed at once.
