The Water Cycle

The Water Cycle  

1.Heat from the Sun causes water on Earth (in oceans, lakes etc) to evaporate (turn from liquid into gas) and rise into the sky.

2.This water vapor collects in the sky in the form of clouds.

3.Only about 3% of the water on Earth is freshwater or water that we can drink.

4.About 70% of the earth is covered with water.

5.Groundwater or water stored in the Earth's surface can remain there for thousands of years before moving.

6.Really old water underground is called fossil water.

7.When water evaporates into the atmosphere, it cools and condenses to form clouds through a process called condensation.

8.Condensation is the process by which water vapor in the air is changed into liquid waterc

9.Evapotranspiration is part of the water cycle, in which the water on Earth moves through a series of states and steps in an endless cycle.

10.Precipitation is water in either solid or liquid form that falls from Earth’s atmosphere.

11.Evaporation is a process where drying or vaporization of a liquid occurs.

12.Infiltration is the process by which water on the ground surface enters the soil. Infiltration rate in soil science is a measure of the rate at which soil is able to absorb rainfall irrigation.
