Water Cycle and the Sun

Water Cycle

The continuous movement of water within the Earth and atmosphere.

Water Cycle

A continuous process of evaporation, condensation, transpiration and precipitation.

The Sun

The sun is what makes the water cycle work. The thermal energy provided by the sun causes evaportation.

Multiple Choice

What drives the water cycle?

• rain

• temperature

• the Sun

• rotation

Multiple Choice

What is another word for thermal energy?

• solar

• wind

• heat

• light

Evaporation

The process by which water changes from a liquid to a gas or vapor.

Condensation

The process by which water vapor (water in its gas form) turns into liquid.

Precipitation

The release of water from the sky, it can be liquid or solid, for example, rain, sleet, hail and snow. Rain begins when small droplets of water join together in the clouds until they become too heavy and gravity pulls them down to earth.

Multiple Choice

This picture of the mirror shows an example of--

• precipitation

• transpiration

• evaporation

• condensation

Multiple Choice

This picture shows -

• evaporation

Transpiration

The release of water from plant's leaves.

Multiple Choice

From all of the step of the water cycle. What is the step of the water cycle when the water goes back into the clouds?

• Evaporation

• Precipitation

• Raining

• Condensation

Multiple Choice

Which of the following events in the water cycle is an example of solar energy being absorbed?

• Water vapor condensing to form clouds.

• Water evaporating from the surface of an ocean.

• Rain freezing as it falls to the ground.

• Clouds releasing precipitation over a mountain.

Multiple Choice

This photograph shows a beach on a partly sunny day. Which of the following is an interaction between the sun and the ocean that results in clouds forming near the beach?

• Energy from the sun causes precipitation over the ocean.

• Energy from the sun causes water to evaporate from the ocean.

• Light from the sun reflects off the surface of the ocean.

• Light from the sun decreases the amount of water vapor in the air over the ocean.

Multiple Choice

The model shows where water can be found during different stages of the water cycle. What should be added to the diagram to better explain the water cycle?

• Soil to trap water from runoff

• Rocks to release thermal energy

• The sun to provide energy for evaporation

• Plants to provide oxygen in the atmosphere
