Understanding the Water Cycle

What is the water cycle?

• The process of water moving continuously between the earth and the atmosphere.

• The process of water being stored in oceans and lakes.

• The process of water being used by plants and animals.

• The process of water being frozen in glaciers.

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

• Precipitation

• Condensation

• Evaporation

• Photosynthesis

What happens during evaporation in the water cycle?

• Water falls from the sky as rain or snow.

• Water turns into vapour and rises into the air.

• Water forms clouds in the sky.

• Water flows into rivers and lakes.

How do humans negatively impact the water cycle?

• By conserving water resources.

• By polluting water bodies.

• By planting more trees.

• By using water efficiently.

What is condensation in the water cycle?

• Water vapour turning into liquid water to form clouds.

• Water flowing into the sea.

• Water being absorbed by plants.

• Water being used by animals.

What is the result of water cooling and condensing in the atmosphere?

• Formation of rivers.

• Formation of clouds.

• Formation of glaciers.

• Formation of oceans.

What is precipitation in the water cycle?

• Water vapour rising into the air.

• Water falling back to earth as rain or snow.

• Water being stored underground.

• Water being used by humans.

Why is it important to understand the water cycle?

• To know how to build dams.

• To understand how to conserve water and protect the environment.

• To learn how to swim.

• To know how to fish.

Which of the following is a way humans can help protect the water cycle?

• By using more plastic products.

• By reducing water pollution.

• By cutting down more trees.

• By increasing industrial waste.

What is the main source of water vapour in the atmosphere?
