• 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 best describes the role of the water cycle?

• circulates existing water on Earth

• reduces pollution in most of the water

• increases usable supply of Earth’s water

If water is recycled in the atmosphere, which best describes why water availability on Earth is decreasing?

• An increase in droughts is slowly reducing freshwater reservoirs.

• Due to an increase in Earth’s temperature, evaporation rates continue to increase reducing liquid water on the surface.

• Earth’s freshwater continues to become more polluted, reducing the supply of freshwater safe for humans to consume.

Which best describes the characteristics of a river basin?

• the land drained by a river and its tributaries

• the land formed when rivers create estuaries and marshes

• the land at the mouth of a river where water flows into the ocean

• the land formed as a result of a river flooding

Why is water from an aquifer more likely to be cleaner than water from other sources?

• because it forms where fresh and salt water meet

• because it receives water directly from precipitation

• because it rises to the surface near the ocean

• because pollutants are filtered by rock and soil deep within Earth

The diagram shows the distribution of water on the Earth. Which source is the most abundant supply of liquid surface water that is not salty?

• groundwater

• oceans

• lakes

• rivers
