The Water Cycle

The Water Cycle

It never stops moving

Movement of Water

• Water on the Earth is continuously moving through the water cycle.

• Water moves through the water cycle in the atmosphere as humidity, clouds, and precipitation. Water also moves in oceans, rivers, lakes, and glaciers.

• The Sun is the major source of energy that moves water through the water cycle.

• Most of the Earth's water can be found in the oceans.

Poll

The Sun is the source of energy that moves water in the water cycle.

• True

• False

Evaporation

The Sun heats up water and causes it to change states from a liquid to a gas. Water changes into water vapor.

Multiple Choice

Sun’s heat causes which of the following movements of water in the water cycle?

• Rivers flowing down mountains

• Evaporation from oceans

• Precipitation from clouds

• Collection of water in lakes

Condensation

As water vapor begins to cool, it changes from a gas back into a liquid in the clouds

Multiple Choice

The labeled diagram shows the water cycle. In the diagram, which letter represents condensation?

• A

• B

• C

• D

Precipitation

Rain, snow, sleet or hail that falls from clouds

Multiple Choice

The labeled diagram shows the water cycle. In the diagram, which letter represents precipitation?

• A

• B

• C

• D

Runoff

When water cannot be absorbed by the ground, it flows down hills, mountains or other surfaces until it collects in a new location such as a pond, stream, creak, river, lake, or ocean.

Collection/

Accumulation

Large amounts of water can gather in a place such as a puddle, lake, ocean, etc.

The water cycle is an important part of daily life. Without it plants and animals as well as life on Earth, would not exist.
