Water Cycle — Answer Key
Part A: Trace the Words
Trace each word carefully by following the dotted lines.
1. water
2. cloud
3. vapor
4. rain
5. steam
6. cycle
Part B: Fill in the Blank
Write the missing word or number on each line.
1. Tiny drops of water make a cloud.
When water gets warm from the sun, it changes into a gas called water vapor. That's how water leaves a puddle without anyone pouring it out.
2. When clouds get heavy, we get rain.
Water vapor is lighter than air, so it floats up into the sky where it can cool down and form clouds.
3. Hot water turns into steam.
When a cloud has too many water drops to hold, it lets them go and they fall to the ground as rain.
4. The water cycle never stops moving.
A loop is a path that circles back to the start. The water cycle works like a loop because water keeps moving from the ground, to the sky, and back again.
Part C: True or False?
Read each statement. Circle True or False.
1. Clouds are made of tiny water drops.
True False
False. Water vapor is a gas, and gas is invisible. You can't see vapor in the air, but you can feel when the air is warm and wet.
2. Rain falls up into the sky.
True False
True. Rain falls onto the land, and the water runs and slides across the ground until it collects in rivers and ponds.
3. Water can turn into vapor when heated.
True False
False. Water keeps moving day and night. Even when you are sleeping, clouds float, rain falls, and water evaporates all around the world.
