The Sun and Water

Water Cycle

The continuous movement of water within the Earth and atmosphere.

Water Cycle

A continuous process of evaporation, condensation, 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

The picture shows a cumulonimbus cloud forming over an ocean. Which statement best explains how the sun and the ocean interact to form a cumulonimbus cloud?

• Heat from the sun warms the ocean causing water to evaporate. The water vapor then condenses to form a cumulonimbus cloud.

Multiple Choice

What is precipitation?

• The part of the water cycle when the sun heats up water, turning it from a liquid into water vapor or steam. It rises from the ground into the air.

• The part of the water cycle when the water vapor in the air gets cold. The water turns back into a liquid and forms clouds.

• The part of the water cycle when clouds get heavy and can no longer hold the liquid water. This causes the water to fall from the sky to the earth as rain, snow, sleet, or hail.
