Power & Heat
100

When the sun heats up liquid water, this process occurs

Evaporation

100

These are the three primary states that water naturally takes on Earth.

Liquid, gas, solid

100

This provides the main source of energy that drives the entire water cycle

The sun

200

This term describes water vapor cooling and changing into liquid water droplets.

Condensation

200

Much of the water that falls to Earth as precipitation flows over the land surface into rivers, lakes, and oceans

Runoff

200

The temperature at which liquid water changes into a solid (or vice versa)

32 (F) or 0 (C)

300

Rain, snow, sleet, or hail falling from clouds are all examples of this

Precipitation 

300

Water that is stored beneath the Earth's surface in soil and rock layers

Groundwater
300

Tiny particles in the air that water vapor condenses around to form clouds

Dust, smoke, or other condensation nuclei

400

The process by which moisture is carried through plants from their roots and released to the atmosphere as water vapor.

Transpiration

400

Only about 3% of all the water on Earth is this type

Freshwater

400

This is the temperature at which water changes from a liquid to a gas.

212 (F) or 100 (C)

500

The downward movement of water through the soil and into rocks below the Earth's surface.

Infiltration

500

Where water is the most abundant in the water cycle

The oceans

500

This force works alongside the Sun's heat to pull precipitation down toward the ground
