1. The Water Cycle:
Notes Part One

2. The Water Cycle
Energy from the sun keeps Earth’s water moving and changing.
Water moves through living and non-living parts on earth, but the amount of water on Earth stays the same

3. The water cycle
-The water cycle is the movement of water between Earth’s surface and the atmosphere.
-The atmosphere is the mixture of gasses and dust that surrounds Earth.

4. The water cycle

5. The Water Cycle
~Water moves from the oceans and land into the air and back again.
~The water cycle has no beginning or end, but you can describe it having four main parts.

6. Part 1
~The sun’s energy warms liquid water on Earth’s surface
~ Some of the liquid changes to a gas-this is called Evaporation, the process of changing a liquid into a gas.
~ Water Vapor (water in the form of a gas) now moves into the atmosphere.

7. Part 1
~Plants pull water from ground through roots into stems and leaves.
~Plants release water vapor through tiny openings in leaves.
~This process is called Transpiration.

8. Part 2
~ As water vapor rises it cools.
~ When it cools enough it turns back into a liquid. This is called Condensation (change from a gas to a liquid)
~Water droplets in the sky form clouds, on the ground it forms dew.
