1.
There are ____ stages in the water cycle.
Correct Answer
C. 4
Explanation
The correct answer is 4 because the water cycle consists of four main stages: evaporation, condensation, precipitation, and collection. During evaporation, water from bodies of water like oceans and lakes turns into water vapor due to the heat from the sun. The water vapor then rises into the atmosphere, where it cools and condenses into clouds during the condensation stage. Next, the condensed water droplets combine and form precipitation, such as rain, snow, or hail, during the precipitation stage. Finally, the water falls back to the Earth's surface and collects in bodies of water, completing the collection stage.
2.
The water cycle begins with ________.
Correct Answer
E. It's a cycle and doesn't have a start or finish
Explanation
The water cycle is a continuous process that does not have a specific starting point or ending point. It is an ongoing cycle where water evaporates from bodies of water, condenses in the atmosphere to form clouds, precipitates back to the Earth's surface as rain, and then collects in bodies of water again. This cycle repeats indefinitely, with each stage leading to the next, creating a continuous loop.
3.
When the Sun heats up the puddle of water in your backyard and turns it into water vapor, this process is known as ________.
Correct Answer
C. Evaporation
Explanation
Evaporation is the process by which a liquid, in this case, water, turns into a gas or vapor due to the heat from the sun. When the sun heats up the puddle of water in the backyard, the water molecules gain enough energy to break free from the liquid and become water vapor in the air. This process is known as evaporation.
4.
When you look outside and it is raining, the water falling down is in what stage of the water cycle?
Correct Answer
A. Precipitation
Explanation
When you look outside and see rain falling, it means that water in the atmosphere has condensed into droplets and is falling to the ground. This stage of the water cycle is called precipitation.
5.
When you see clouds forming in the sky, the water above you is forming droplets in what stage of the water cycle?
Correct Answer
B. Condensation
Explanation
When clouds form in the sky, it indicates that the water vapor in the air is cooling down and changing into liquid water droplets. This process is known as condensation. As the water vapor rises and cools, it reaches its dew point and condenses onto tiny particles in the air, forming visible clouds. Therefore, when clouds are forming in the sky, it is a clear indication that condensation is occurring in the water cycle.
6.
The water that was around when dinosaurs roamed the Earth:
Correct Answer
C. Is the same water we use today
Explanation
The answer "Is the same water we use today" suggests that the water that was around when dinosaurs roamed the Earth has not disappeared or diminished significantly over time. This implies that the water on Earth is a closed system, meaning that it is constantly recycled through the water cycle. This process involves evaporation, condensation, and precipitation, which ensures that the same water molecules are continuously reused and redistributed on the planet. Therefore, the water we use today is essentially the same water that has been on Earth for millions of years.
7.
Once water makes it all the way through the water cycle, the water ________.
Correct Answer
B. Continues its cycle
Explanation
After completing the water cycle, water does not disappear or take a break, but rather it continues its cycle. The water evaporates from bodies of water, forms clouds through condensation, falls back to the Earth as precipitation, and then collects in bodies of water again. This continuous process of evaporation, condensation, and precipitation is known as the water cycle.
