Steps in the Water Cycle

The Water Cycle

How does water enter and leave the atmosphere?

Review -

The Water Cycle

• The sun shines on liquid water, and the particles heat up and spread out.

• The liquid water becomes a gas called vapor and rises to the sky.

• The atmosphere cools the vapor, which packs close together to form clouds.

• The vapor turns back into a liquid, and gravity pulls it down as precipitation.

Reorder

Sequence these events in the water cycle.

• START: The sun heats the liquid water.

• Water vapor expands and rises to the atmosphere.

• The atmosphere cools the vapor.

• The vapor packs together to form clouds.

• Gravity pulls the water back to Earth's surface.
