Question 1

What is the water cycle?

Accepted Answer

The water cycle is the journey water takes as it moves from the sky to the ground and back again. This journey helps keep water fresh and clean for us to use.

Question 2

How does water get from the ground to the sky?

Accepted Answer

Water from rivers, lakes, and oceans heats up and turns into vapor, which goes into the air. This process is called evaporation.

Question 3

What is evaporation?

Accepted Answer

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

Question 4

What happens when water vapor goes into the air?

Accepted Answer

The water vapor cools down and forms tiny droplets, making clouds. This part of the cycle is called condensation.

Question 5

What is condensation?

Accepted Answer

Condensation is when water vapor turns back into little droplets of water. These droplets gather together to form clouds.

Question 6

How do clouds form?

Accepted Answer

Clouds are made up of tiny water droplets or ice crystals. They form when water vapor cools down and condenses in the sky.

Question 7

What makes rain fall from the clouds?

Accepted Answer

When cloud droplets join together and get heavy, they fall as raindrops. This is called precipitation.

Question 8

What is precipitation?

Accepted Answer

Precipitation is water that falls from the sky as rain, snow, sleet, or hail. It's how water returns to the Earth's surface.

Question 9

Why is the water cycle important?

Accepted Answer

The water cycle gives us the fresh water we need to drink, grow plants, and live. It also helps keep the Earth's temperature stable.

Question 10

Can plants affect the water cycle?

Accepted Answer

Yes! Plants release water vapor into the air through their leaves. This is called transpiration and it helps add water to the air.

Question 11

What is transpiration?

Accepted Answer

Transpiration is when plants release water vapor into the air from their leaves. It is an important part of the water cycle.

Question 12

Does all water in the water cycle start as rain?

Accepted Answer

Not all water starts as rain. Water can come as snow, hail, or sleet too, which are all types of precipitation.

Question 13

Where does the water in the oceans come from?

Accepted Answer

The water in the oceans mostly comes from rainfall and rivers. It also comes from melting ice.

Question 14

How does water from the ocean return to the sky?

Accepted Answer

Water from the oceans evaporates into the air when it's warmed by the sun. This is one way water vapor enters the atmosphere.

Question 15

Why don't oceans dry up from all the evaporation?

Accepted Answer

As water evaporates, precipitation like rain refills the oceans and keeps the cycle going. This balance prevents oceans from drying up.

Question 16

What is groundwater?

Accepted Answer

Groundwater is water that soaks into the soil and fills underground spaces. It is an important source of water for plants and people.

Question 17

How does groundwater return to the water cycle?

Accepted Answer

Groundwater can flow into rivers, lakes, and oceans. It can also be drawn up by plants and eventually evaporates back into the air.

Question 18

Does the water cycle ever stop?

Accepted Answer

No, the water cycle is always happening. It's a continuous process that keeps moving water around the Earth.

Question 19

Can we see all parts of the water cycle?

Accepted Answer

We can see parts like rain and clouds. But some parts, like evaporation and transpiration, are harder to see because they're happening as an invisible gas.

Question 20

How does snow fit into the water cycle?

Accepted Answer

Snow is a type of precipitation. When it melts, it turns into water and flows into rivers or soaks into the soil, continuing the cycle.
