The Water Cycle-Demos for each stage of the hydrologic cycle

Monday, February 24, 2020

The water we drink today is the same water that dinosaurs drank. How can this be?
Water moves around and around and is constantly moving from one location to another or one phase to another.


9 Key Steps of the water cycle

Evaporation: When water is heated it changes from a liquid to a gas.

Condensation: When water is in gas form and is cooled then it will change from a gas to a liquid.

Precipitation: When you get a large amount of condensation the liquid water may fall to the Earth in the form of rain, sleet, snow, or hail.

Transpiration: You may think of transpiration as plants sweating. Plants give off excess water into the atmosphere in the form of vapor.

Infiltration occurs when groundwater enters the soil.

Groundwater: As water moves through the soil it may accumulate in open spaces, and cracks in the soil.

Aquifer: Think of an aquifer as an underground sponge that soaks up water as the water infiltrates through the soil.

Run-off: When the precipitation is so great that the water accumulates on the ground run-off may occur.

Accumulation: A lake, the ocean, and a pond are examples of accumulation.

Water is constantly moving between these 9 key steps.
