Here are the correct answers for the Water Cycle Quiz, with a quick explanation for each one to help you understand why.
1. The water cycle starts with the energy from the \_\_\_\_\_\_.
*
Answer: sun
*
Why: The sun provides the heat energy that warms up the water in oceans and lakes, causing it to turn into vapor (evaporation). Without the sun's heat, the water would stay still.
2. Evaporation is when \_\_\_\_\_\_.
*
Answer: water changes from a liquid to a gas
*
Why: Evaporation happens when liquid water gets hot enough to turn into an invisible gas called water vapor. It floats up into the air.
3. Constant movement of water is called \_\_\_\_\_\_.
*
Answer: the water cycle
*
Why: The whole process of water moving from the ground to the sky and back again is known as the water cycle. It never stops!
4. The water that falls from the clouds is \_\_\_\_\_\_.
*
Answer: precipitation
*
Why: When clouds get too heavy with water droplets or ice crystals, they fall down as rain, snow, hail, or sleet. This falling water is called precipitation.
5. The water cycle is \_\_\_\_\_\_.
*
Answer: natural
*
Why: The water cycle is a process that happens in nature all by itself. Humans don’t build machines to make it happen; it’s part of how Earth works.
6. The stages of the water cycle are: \_\_\_\_\_\_.
*
Answer: evaporation, condensation, precipitation
*
Why: These are the three main steps:
1.
Evaporation: Water turns to gas and goes up.
2.
Condensation: Gas cools down and forms clouds.
3.
Precipitation: Water falls back down from clouds.
7. Dew is an example of \_\_\_\_\_\_.
*
Answer: condensation
*
Why: Dew forms when water vapor in the air touches something cool (like grass) and turns back into liquid water droplets. This change from gas to liquid is condensation.
8. Puddles that disappear on a warm day is an example of \_\_\_\_\_\_.
*
Answer: evaporation
*
Why: On a warm day, the sun heats up the puddle. The water turns into vapor and rises into the air, making the puddle "disappear." This is evaporation.
9. Evaporation comes mostly from \_\_\_\_\_\_.
*
Answer: oceans
*
Why: Oceans cover most of the Earth’s surface. Because they are so huge, they provide the largest amount of water that evaporates into the atmosphere.
