Where is most of Earth’s freshwater located?

• in the clouds

• in the ice caps

• in the ocean

• in the ground

Which of the following contains MOST of the water on Earth?

• the oceans

• watersheds

• the atmosphere

• ice and aquifers

During a portion of the water cycle, water falls to Earth’s surface as precipitation. Some of this water runs off into channels and keeps moving until it ends up in the ocean.

Which BEST describes the water in the channels?

• lake

• river

• aquifer

• wetland

Which percentage represents the amount of Earth’s water that is found in oceans?

• 3%

• 71%

• 97%

Which best describes the characteristics of a river basin?
