1 Water Cycle The Hydrologic Cycle

2 I’ve got the power!

3 Evaporation Eventually the vapor rises into the air and collects in clouds.   Heat energy from the sun causes water in puddles, streams, rivers, seas, oceans or lakes to change from a liquid to water vapor (a gas). This is called evaporation.

4 Transpiration Transpiration is the process by which plants lose water out of their leaves.  Transpiration gives evaporation a bit of a hand in getting the water vapor back up into the air.

5 Condensation As water vapor rises and cools, it collects around dust particles (or condenses) and forms clouds.Water vapor (a gas) becomes liquid again. This is called condensation.

6 Precipitation This is called precipitation.
When clouds are saturated gravity pulls the water to the earth. Mainly as rain, but sometimes as snow, sleet, and hail. This is called precipitation.

7 Run Off Surface run off: movement of water on Earth’s surface to collect in rivers, streams, lakes and oceans. Subsurface run off: movement of water beneath the Earth’s surface that eventually collects in aquifers and springs.

8 Infiltration occurs when the water moves from the surface into the soil.
Then water percolates down through the soil. The rate of percolation depends on the type of soil.

9 Accumulation a.k.a. collection
Water collects in rivers, lakes, streams, and the ocean.
