Water Cycle Basics Quiz

Grade 2 · Science · Quiz

Test what you know about how water moves through the water cycle.

Questions

1. What happens during evaporation?

   1. Water falls from the sky as rain
   2. Water vapor forms clouds
   3. Liquid water turns into water vapor
   4. Water soaks into the ground
   Show answer

   Answer: Liquid water turns into water vapor

   Evaporation is when liquid water is heated and turns into water vapor, an invisible gas that rises into the air.

2. Which of these is NOT a form of precipitation?

   1. Rain
   2. Snow
   3. Fog
   4. Hail
   Show answer

   Answer: Fog

   Fog is not precipitation because it does not fall from clouds. Fog is water vapor near the ground. Rain, snow, and hail all fall from clouds.

3. Water vapor is a liquid you can see easily.

   Show answer

   Answer: False

   Water vapor is an invisible gas. You cannot see it, even though it is all around you in the air.

4. What forms when water vapor rises and cools in the sky?

   1. Rain
   2. Clouds
   3. Wind
   4. Soil
   Show answer

   Answer: Clouds

   When water vapor rises and cools, the vapor changes back to tiny liquid droplets that gather together to form clouds.

5. What gives the water cycle its energy to keep going?

   1. Wind
   2. The moon
   3. The sun
   4. Animals
   Show answer

   Answer: The sun

   The sun provides the heat energy that evaporates water and powers the entire water cycle.

6. Water can fall from clouds as snow when the air is very cold.

   Show answer

   Answer: True

   When the air is very cold, precipitation falls as snow instead of rain. Both are forms of water falling from clouds.

7. What is condensation?

   1. Water turning into a gas
   2. Water falling as rain or snow
   3. Water vapor cooling and forming tiny water droplets
   4. Water soaking into the soil
   Show answer

   Answer: Water vapor cooling and forming tiny water droplets

   Condensation is when water vapor cools down and changes back into tiny liquid water droplets, forming clouds.

8. After precipitation, where does water collect?

   1. In the sky
   2. In clouds
   3. In oceans, lakes, and rivers
   4. In the sun
   Show answer

   Answer: In oceans, lakes, and rivers

   After precipitation, water collects in oceans, lakes, rivers, and the ground. Then the sun evaporates it again and the cycle continues.
