Forces that move water
Water moving across land
Tracking a drop of water
100

When plants release water vapor into the air through tiny pores in their leaves, it is called this 

Transpiration

100

This force pulls all forms of precipitation back down to the earth's surface....and it is the same force that is responsible for keeping us on the ground

gravity

100

This is when gravity pulls water down into the earth, through soil and rock layers

Infiltration
200

When water vapor cools down and turns back into tiny water drops it is called this

Condensation

200

This force heats water up and lifts it into the atmosphere as vapor

Solar Energy

200

Gravity pulls rainwater downhill across hillsides, streams, and rivers until it returns to the oceans. 

Surface Runoff

300

This is stored in clouds and when the clouds get too heavy, it falls back down to the earth in forms such as rain, snow, sleet and hail

Precipitation

300

As the water molecules are heated up, they gain energy and move faster and spread apart. They turn from a liquid into an invisible gas called ...

Water Vapor

400

This is when water warms up and turns into an invisible water vapor

Evaporation

400

The sun gives off heat energy, which heats the water and can cause skin problems like sunburn and in worst cases, skin cancer

Solar Radiation

400

Will Earth ever run out of water? Explain

No, because the same amount of water that evaporates into the atmosphere matches the amount that falls back as precipitation. Solar Energy and Gravity work together to keep it balanced. 

500

Please put these stages of the water cycle in order

Water Vapor cools high in the air and condenses into a cloud.

Gravity pulls heavy droplets to the ground as rain.

Surface runoff flows downhill through rivers back into the oceans.

Sunlight warms ocean water, turning liquid into water vapor


1. Sunlight warms ocean water, turning liquid into water vapor

2. Water vapor cools high in the air and condenses into a cloud

3. Gravity pulls heavy droplets to the ground as rain

4. Surface runoff flows downhill through rivers back into the ocean.
