Science: The Water Cycle Worksheet

Question 1

What is the water cycle?

Accepted Answer

The water cycle is the way water moves from Earth's surface into the air and back to the ground again.

Question 2

What is evaporation?

Accepted Answer

Evaporation is when liquid water warms up and changes into water vapor that rises into the air.

Question 3

What is condensation?

Accepted Answer

Condensation is when water vapor cools and changes into tiny drops of liquid water that form clouds.

Question 4

What is precipitation?

Accepted Answer

Precipitation is water that falls from clouds to the ground as rain, snow, sleet, or hail.

Question 5

Name two kinds of precipitation.

Accepted Answer

Two kinds of precipitation are rain and snow.

Question 6

After rain falls into a lake, where can the water go next in the water cycle?

Accepted Answer

After rain falls into a lake, the water can evaporate into the air again.

Question 7

What helps cause evaporation: the Sun or the Moon?

Accepted Answer

The Sun helps cause evaporation because its heat warms the water.

Question 8

Clouds are made of tiny drops of water or ice. Which part of the water cycle does this show?

Accepted Answer

This shows condensation because water vapor has cooled and formed clouds.

Question 9

Put these parts of the water cycle in order: condensation, collection, evaporation, precipitation.

Accepted Answer

A correct order is evaporation, condensation, precipitation, and collection.

Question 10

True or false: Water in the water cycle is used once and then disappears forever.

Accepted Answer

This statement is false because water keeps moving through the water cycle again and again.

Question 11

What is collection in the water cycle?

Accepted Answer

Collection is when water gathers in places like oceans, lakes, rivers, and puddles.

Question 12

If wet clothes dry outside on a sunny day, which part of the water cycle is happening?

Accepted Answer

Evaporation is happening because the liquid water in the clothes changes into water vapor.

Question 13

Why do clouds sometimes produce rain?

Accepted Answer

Clouds sometimes produce rain when the water drops in them get heavy enough to fall to the ground.

Question 14

How does water get from the ground into the clouds?

Accepted Answer

Water gets from the ground into the clouds by evaporating into the air and then condensing into tiny drops.

Question 15

Explain why the water cycle is important for living things.

Accepted Answer

The water cycle is important because it helps move fresh water around Earth so plants, animals, and people can use it.
