The Water Cycle

By Megan & Jayda

What is The Water Cycle?

The Water Cycle describes how water evaporates from the surface of the earth, rises into the atmosphere, cools and condenses into rain or snow in clouds, and falls again to the surface as precipitation. The water falling on the land collects in the river ,soil and porous layers of rock, and much of it flows back into the ocean, where it will once more be evaporated. The cycling of water in and out of the atmosphere is a significant aspect of the weather patterns on earth.

How many steps are in The Water Cycle?

There are four main steps in The Water Cycle, They are evaporation, condensation, precipitation, and filtration.

Evaporation: This is when warmth from the sun causes water from oceans, lakes, streams, ice and soils to rise into the air and turn into water vapor (gas). Water vapor droplets join together to make clouds!

Condensation: This is when water vapor in the air cools down and turns back into liquid water.

Precipitation: This is when water (in the form of rain, snow, hail or sleet) falls from clouds in the sky.

Filtration: This is when water that falls from the clouds as rain, snow, hail or sleet, collects in the oceans, rivers, lakes, streams. Most will infiltrate (soak into) the ground and will collect as underground water.

The water cycle is powered by the sun's energy and by gravity. The sun kickstarts the whole cycle by heating all the Earth's water and making it evaporate. Gravity makes the moisture fall back to Earth.
