Understanding the Water Cycle

Which of the following processes in the water cycle involves the transformation of water from a liquid to a gas?

• Precipitation

• Evaporation

• Condensation

• Infiltration

What is the primary source of energy that drives the water cycle?

• Wind

• The Sun

• The Moon

• Earth's core

During which stage of the water cycle does water vapor cool and change back into liquid droplets?

• Evaporation

• Transpiration

• Condensation

• Sublimation

Which of the following best describes the process of infiltration in the water cycle?

• Water flowing over the surface of the ground

• Water soaking into the soil from the surface

• Water being absorbed by plant roots

• Water evaporating from the surface of leaves

What role do plants play in the water cycle?

• They release water vapor into the atmosphere through transpiration.

• They absorb water vapor from the atmosphere.

• They prevent water from evaporating.

• They convert water into oxygen.

Which of the following is NOT a part of the water cycle?

• Evaporation

• Photosynthesis

• Precipitation

• Condensation

How does precipitation contribute to the water cycle?

• It returns water to the Earth's surface from the atmosphere.

• It converts water into vapor.

• It allows water to seep into the ground.

• It causes water to flow into rivers and oceans.

Which of the following processes is responsible for the movement of water from plants to the atmosphere?

• Evaporation

• Transpiration

• Condensation

• Infiltration

What happens to water molecules during the process of sublimation in the water cycle?

• They change from a solid directly to a gas.

• They change from a liquid to a solid.

• They change from a gas to a liquid.

• They change from a liquid to a gas.

Which of the following best explains the role of runoff in the water cycle?

• It is the process by which water is absorbed by plants.

• It is the movement of water across the surface of the land into bodies of water.

• It is the process of water vapor turning into liquid water.

• It is the process of water seeping into the ground.
