Text, Questions & Answers

Water is amazing! It can change into three forms: liquid, solid, and gas. This transformation is called the Water Cycle. It involves four steps - evaporation, condensation, precipitation, and collection. The sun's heat causes water to evaporate from rivers, oceans, and even your clothes. This water vapor turns back into water droplets when it cools down in the sky - that's condensation. These droplets fall back to Earth as rain or snow, which we call precipitation. Finally, the water is collected in oceans and rivers, and the cycle starts all over again! And guess what, the water you drank today could have been the same water dinosaurs drank millions of years ago!

Question 2

What causes water to evaporate?

C

The sun's heat

Explanation. The sun's heat causes water to evaporate from rivers, oceans, and even your clothes.

Question 3

What is the step in the water cycle when water vapor turns back into water droplets?

A

Evaporation

B

Precipitation

C

Collection

D

Condensation

Explanation. Condensation is the process in which water vapor in the air cools down and turns back into liquid water.

E

Transpiration

Question 4

What is the term for the stage in the water cycle when water droplets fall back to the Earth as rain or snow?

A

Collection

B

Evaporation

C

Condensation

D

Precipitation

Explanation. Precipitation is when water (in the form of rain, snow, sleet, or hail) falls from clouds in the sky.

E

Transpiration

Question 5

Where is water collected in the final stage of the water cycle?

A

In the clouds

In the sun

C

In the atmosphere

D

In the soil

E
