Information report - Water Cycle

The water cycle is a process that water goes through between ground ocean and sky. The steps of the water cycle are: Evaporation, condensation, precipitation and runoff/ground water.

Evaporation is when the water gets heated and turns into a gas. When water hits the boiling point (around 100 degrees centigrade)it turns into a gas and rises into the atmosphere. Evaporation changes liquid and frozen water into water vapor gas. The suns energy breaks the bonds that holds water molecules together. When water vapor gas rises it forms clouds.

Condensation and precipitation is the clouds that form in the sky. water vapor gas condenses back into water and ice when it gets to cold. Higher in the atmosphere where its colder water vapor turns back into droplets.As the water droplets get heavier they can no longer float causing them to fall. Precipitation isn't always rain it could also be snow, sleet or hail. After it rains, snows sleets or hails the water needs to get back into the ocean or river this is called runoff.

Runoff/ ground water is when the water needs to get back to the ocean or river. Runoff water travels to rivers, lakes or oceans, keeping the water going. Water underground moves due to gravity downward and sideways. Ground water has purposes such as keeping plants alive and filling aquifers. Runoff is important because it flows over land. Most of it soaks into the soil and creates groundwater.

The water cycle is a process of stages: Evaporation, Condensation, precipitation, and runoff. The water cycle has no start of finish. All water is recycled
