2. The Water Cycle
Also Known as the hydrologic cycle

3. The Hydrosphere
All the water that occurs at Earth’s surface is the hydrosphere

4. The Driving Force The sun provides the energy for the water cycle
radiation from the sun causes water to change to a gas called water vapor.

5. Evaporation
The process of water changing from a liquid state to a gas is called evaporation.

6. Condensation Water vapor rises in the atmosphere and cools
When it is cool enough it changes back into a liquid
When water vapor condenses it forms clouds

7. Precipitation
Clouds are made up of millions of tiny water droplets that collide and form larger drops
When the drops get too large and heavy to remain suspended, they fall to Earth

8. Transpiration
Transpiration is the evaporation of water into the atmosphere from the leaves and stems of plants.
Plants absorb soilwater through their roots.
