Summary

Fill in the blanks to complete the summary.

When water vapor rises into the sky, it is cooled by air and changes into tiny water droplets.

It is called condensation , and we see these droplets as a cloud. Rain is droplets of water

that fall from clouds . Where does the water vapor that changes into clouds or

rain come from? Water from oceans and rivers evaporates into the atmosphere . This vapor

changes into clouds and gets too heavy to stay suspended in the cloud as more

water droplets collide . Then, they fall as rain and go into oceans and rivers again. This

process, which is called the water cycle , goes on continuously. It shows how

water moves on Earth.
