UNIT TEST - HYDROSPHERE

A student walks to school one morning and notices the grass is wet but the street are dry- Which of these processes most likely caused the grass to be wet?

• Condensation

• Erosion

• Evaporation

• Precipitation

Runoff from farms that use fertilizers is entering a small lake. This will most directly affect the lake by causing...

• the lake to dry up

• algae to grow in the lake

• the lake to become deeper

• Water in the lake to become solid

Which statement best describes runoff?

• water vapor cools off and changes into water droplets

• water in the form of rain, snow, sleet, or hail falls from clouds.

• precipitation that falls to Earth ultimately flows over land into lakes, streams and rivers

• Water from the oceans and the surface of the earth changes into water vapor.

Which of the following is an example of the condensation in the water cycle?

• clouds forming in the atmosphere

• drops of water falling through the air

• puddles disappearing on a hot day

• streams flowing into rivers

In the water cycle, rain, snow or sleet falling to the ground is a form of

• precipitation

• condensation

• evaporation

• transpiration

Clouds are formed from tiny drops of water that are light enough to float in the air. As these drops bump into each other, they form larger drops. What happens when these drops become too heavy to float in the air

• the drops form fog.

• the drops evaporate

• the drops fall as rain

• the drops become air

This picture shows the path of a river - What is the name of the for the curves in the river

• Delta

• Floodplain

• Meanders

• Tributaries

Which of the following is an example of the condensation in the water cycle?

• Clouds forming in the atmosphere

• Drops of water falling through the air

• Puddles disappearing on a hot day

• Streams flowing into rivers

Where is the majority of Earth's freshwater located?

• Clouds

• Pacific Ocean

• Polar Ice Caps

• Rivers

Which two processes in the water cycle are primarily responsible for the creation of a lake?

• evaporation and runoff

• evaporation and condensation

• precipitation and runoff

• precipitation and condensation
