Water never leaves the Earth. It is constantly being cycled through the atmosphere, ocean, and land. This process, known as the water cycle, is driven by energy from the sun.

Evaporation Back
- During part of the water cycle, the sun heats up liquid water and changes it to a gas by the process of evaporation.
- Water that evaporates from Earth’s oceans, lakes, rivers, and moist soil rises up into the atmosphere.
- Warmth from the sun causes water from lakes, streams, ice, and soils to turn into water vapor in the air.
- Almost all of the precipitated water (80 percent) goes right back into the air because of evaporation.
Condensation Back
- The process in which water vapor (a gas) in the air turns into liquid water.
- Condensing water forms clouds in the sky. Water drops that form on the outside of a glass of icy water are condensed water.
Surface Runoff
Back
- Rain, snow melt, or other water that flows in surface streams, rivers, or canals.
Precipitation Back
- Precipitation is made up of any type of water that falls to the earth like snow, hail, sleet, freezing rain, or rain.
- Most of it (80 percent) evaporates or transpires through plants and never reaches lakes, streams, or ground water.
- The rest, runs off the land into lakes, streams, wetlands or rivers (also called "surface water"), or, it soaks right into the ground (infiltration).
Infiltration
Back
- Infiltration happens when water soaks into the soil from the ground level. It moves underground and moves between the soil and rocks. Some of the water will be soaked up by roots to help plants grow.
- The plants leaves eventually release the water into the air through the plant s pores. (Transpiration)
- Some of the water keeps moving down into the soil to a level that is filled with water, called ground water. The very top of this layer filled with ground water is called the water table.
Transpiration
Back
- Transpiration happens when plants give off water vapor through tiny pores in their leaves. This is the plant s way of getting rid of waste, just like people and animals sweat when they're hot!
- This water vapor evaporates into the air and is stored in the atmosphere until it becomes clouds or precipitation.
Accumulation
Back
- the process in which water pools in large bodies (like oceans, seas and lakes).
