Water Cycle 11-04-2019

What type of energy drives the water cycle?

• mechanical

• solar

• wind

• chemical

The diagram below shows the water cycle.Which letter represents the process of evaporation?

• B

• C

• A

• D

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 become air.

• The drops fall as rain.

Over 7 billion people on Earth use water every day, yet Earth’s water supply remains relatively constant. Which statement best explains this?

• Water is constantly recycled by the water cycle.

• The sea level is rising.

• Water exists in three phases on Earth.

• Global warming melts ice to replace water that is used.

Which processes of the water cycle return water vapor directly to the atmosphere?

• freezing and precipitation

• evaporation and transpiration

• infiltration and capillarity

• water retention and runoff

During one growing season, 5,000 square meters of corn plants transpire approximately 1.85 million liters of water. The water lost from the plants via transpiration goes directly to which of the following?

• insects

• the soil

• stream

• the atmosphere

The diagram represents part of the water cycle. What part of the water cycle is represented by arrow Y?

• condensation

• evaporation

• precipitation

• infiltration

The flowchart below shows part of Earth’s water cycle. The question marks indicate a part of the flowchart that has been deliberately left blank.

• evaporation

• condensation

• deposition

• runoff

Which of the following is an example of water condensing?

• Water disappearing from a bowl.

• Ice cubes disappearing in a glass of water.

• Bubbles forming in a pot of water as it is heated.

• Drops of water forming on the outside of a cold glass.

The arrows in the diagram below represent the movement of water in the water cycle. Which arrow represents runoff?
