Water Cycle

What is the term for the process where plants release water vapor from their leaves?

• Transpiration

• Photosynthesis

• Respiration

• Evaporation

What is the process called when water falls from clouds to the ground?

• Evaporation

• Condensation

• Precipitation

• Transpiration

What is evaporation?

• Evaporation is the process where liquid water is transformed into water vapor due to heat.

• Evaporation is the process of turning solid ice directly into water vapor.

• Evaporation is the process of cooling water by removing heat.

• Evaporation is the process of mixing water with other liquids.

What do we call the water that flows from land into rivers, streams, and eventually to oceans?

• Runoff

• Evaporation

• Condensation

• Precipitation

What happens during precipitation?

• Water droplets in clouds combine and fall to the ground as rain, snow, sleet, or hail.

• Water evaporates from the ground and forms clouds in the sky.

• Clouds disperse and release heat into the atmosphere.

• Water is absorbed by the soil and used by plants.

How does temperature affect the rate of evaporation?

• Higher temperatures increase the rate of evaporation.

• Lower temperatures increase the rate of evaporation.

• Temperature has no effect on the rate of evaporation.

• Higher temperatures decrease the rate of evaporation.

What is the significance of the sun in the water cycle?

• The sun provides the energy needed for evaporation and drives the water cycle.

• The sun cools the water and prevents evaporation.

• The sun has no effect on the water cycle.

• The sun only affects the water cycle at night.

Does the water cycle have a beginning and an end?

• Yes, it has a definite beginning and end.

• No, the water cycle has no beginning and no end.

• Yes, it begins with evaporation and ends with precipitation.

• No, it is a continuous process without a start or finish.

What role do clouds play in the water cycle?

• Clouds are formed from condensed water vapor and are essential for precipitation.

• Clouds block sunlight and prevent evaporation.

• Clouds are made of dust particles and have no role in precipitation.

• Clouds are only formed during storms and do not affect the water cycle.

What is groundwater?

• Water that is stored underground in soil and rock layers.

• Water that is found in rivers and lakes.

• Water that evaporates from the surface of the earth.

• Water that is used for irrigation purposes only.
