Water Cycle

Water Cycle Thumbnail
The water cycle, also called the hydrological cycle, shows how water moves through the environment on Earth. Evaporation, condensation, precipitation, and recharging are all parts of the cycle. Can you fine tune each of these cycle elements to create the most efficient water cycle possible? Get ready to pour yourself into this investigation of the water cycle.

What is the Water Cycle?

A process that shows how water circulates through the atmosphere, hydrosphere, and lithosphere in a continuous process.

What is evaporation?

The process in which liquids move into the gas phase below the temperature at which the liquid normally boils.

What is transpiration?

The process in which liquid water is released through pores in leaves and moves into the gas phase.

What is sublimation?

The process in which solids move directly into the gas phase without first moving through the liquid phase.

What is condensation?

The process in which a gas moves into the liquid phase.

What is precipitation?

Water in the atmosphere in the solid or liquid phase that falls from clouds to the ground.

What is melting?

The process in which solids move into the liquid phase.

What is infiltration?

When precipitation that falls on the ground moves through the solid Earth and down into underground reservoirs.

What is runoff?

When precipitation that falls on the ground moves along the surface of the ground or from below the surface into surface waters.
