Lesson 6: Earth’s Water Cycle

Page 2: Lesson 6: Earth’s Water Cycle. What is the Water Cycle? The water cycle is the continual movement of Earth’s water between the land, ocean, and air

What is the Water Cycle?The water cycle is the continual

movement of Earth’s water between the land, ocean, and air.

4. Collection and Runoff

There are Four Stages to Earth’s Water Cycle:

Page 5: Lesson 6: Earth’s Water Cycle. What is the Water Cycle? The water cycle is the continual movement of Earth’s water between the land, ocean, and air

Evaporation is the process by which the sun’s energy changes water from a liquid

to a gas.

This gas is called water vapor.

Page 6: Lesson 6: Earth’s Water Cycle. What is the Water Cycle? The water cycle is the continual movement of Earth’s water between the land, ocean, and air

This water vapor collects in Earth’s atmosphere to form clouds.

This process is called condensation.

Page 7: Lesson 6: Earth’s Water Cycle. What is the Water Cycle? The water cycle is the continual movement of Earth’s water between the land, ocean, and air

As clouds become heavy from the condensed water vapor, the water will fall

back to earth as rain, snow, or sleet.

These are examples of precipitation.

Page 8: Lesson 6: Earth’s Water Cycle. What is the Water Cycle? The water cycle is the continual movement of Earth’s water between the land, ocean, and air

Precipitation can collect in bodies of water, run off from higher areas of land, or be

absorbed into the ground.

Collection and runoff provide water for life on Earth.

The water cycle is an ongoing process that continues to repeat itself.

Earth’s Water Cycle Key Questions

1. What occurs during each stage of the water cycle?

2. What provides energy for the water cycle? Explain

3. Why is the water cycle necessary for life on Earth?
