Question 1

What is the water cycle?

Accepted Answer

The water cycle is the way water moves around the Earth. It goes from the ocean to the sky, then as rain or snow to the ground, and back to the ocean again.

Question 2

How does water get into the air?

Accepted Answer

Water gets into the air when it evaporates. This happens when the Sun heats up water in rivers, lakes, and oceans, turning it into a vapor or gas.

Question 3

What happens when water vapor cools down?

Accepted Answer

When water vapor cools down, it turns back into tiny drops of water. These tiny drops come together to form clouds.

Question 4

Why do clouds form in the sky?

Accepted Answer

Clouds form when water vapor in the sky cools down and turns into tiny water drops. These drops group together and make a cloud.

Question 5

What is rain?

Accepted Answer

Rain is water falling from clouds. When the tiny droplets in clouds get big and heavy, they fall to the ground as raindrops.

Question 6

How does snow form?

Accepted Answer

Snow forms when the water droplets in clouds freeze into tiny ice crystals. These crystals stick together to make snowflakes that fall to the ground.

Question 7

What is evaporation?

Accepted Answer

Evaporation is when the Sun heats up water and turns it into a gas called water vapor. This gas then rises into the sky.

Question 8

What is condensation?

Accepted Answer

Condensation is when water vapor cools down and turns back into liquid water. It’s like when your cold drink has water droplets on the outside because the air hits it.

Question 9

Where does rainwater go?

Accepted Answer

Rainwater can soak into the ground, quenching plants and filling underground reservoirs. Some of it flows into rivers and lakes, eventually making its way back to the ocean.

Question 10

How does water return to the ocean?

Accepted Answer

Water returns to the ocean through rivers and streams. After it rains, water flows over the ground and into rivers that lead back to the sea.

Question 11

Why is the water cycle important?

Accepted Answer

The water cycle is important because it provides fresh water for plants, animals, and people to drink. It also helps keep our planet cool.

Question 12

Can you see evaporation happening?

Accepted Answer

You can't see water vapor because it’s a gas. But you can see evaporation when you notice a puddle disappearing after a sunny day.

Question 13

Do plants play a role in the water cycle?

Accepted Answer

Yes, plants take in water through their roots and release water vapor into the air through their leaves. This process is called transpiration.

Question 14

What is transpiration?

Accepted Answer

Transpiration is when plants release water vapor into the air through small holes in their leaves. It's similar to how we sweat!

Question 15

Why does it sometimes hail instead of rain?

Accepted Answer

Hail forms when raindrops are carried high into a cloud and freeze. These frozen balls can grow bigger if more layers of ice form on them before falling to the ground.

Question 16

What is groundwater?

Accepted Answer

Groundwater is water that is stored under the Earth’s surface. It fills the spaces between rocks and soil, and is a source of water for wells and plants.

Question 17

How do humans affect the water cycle?

Accepted Answer

Humans affect the water cycle by using water for drinking, farming, and cleaning. Pollution and changes to rivers and lakes can also impact how water moves around the Earth.

Question 18

What might happen if the water cycle changes?

Accepted Answer

If the water cycle changes, it can lead to too much rain or not enough, causing floods or droughts. This can affect crops, animals, and people who need water.

Question 19

Can all the water in the water cycle be used by people?

Accepted Answer

Not all water in the cycle can be easily used by people. Some water is salty or frozen, or deep underground, making it hard for us to use.

Question 20

How can we take care of the water cycle?

Accepted Answer

We can care for the water cycle by saving water, keeping our rivers and lakes clean, and protecting the environment. This helps make sure there's enough water for everyone.
