Question 1

What is the hydrological cycle?

Accepted Answer

The hydrological cycle is the way water moves around our planet. It goes up into the sky, forms clouds, falls back down as rain or snow, and flows through rivers and oceans.

Question 2

How does water get into the sky?

Accepted Answer

Water gets into the sky when it evaporates, which means it turns into a gas called water vapor. This happens when the sun heats up water in rivers, lakes, and oceans.

Question 3

What happens to water vapor in the sky?

Accepted Answer

In the sky, water vapor cools down and turns back into tiny water droplets, forming clouds. This process is called condensation.

Question 4

Why do clouds look like they’re moving?

Accepted Answer

Clouds move because of the wind. The wind pushes clouds across the sky, sometimes over long distances.

Question 5

What makes rain fall from the clouds?

Accepted Answer

Rain falls from clouds when the tiny water droplets combine and become too heavy to stay up in the sky. Gravity pulls them down to Earth.

Question 6

What happens to rain after it falls?

Accepted Answer

After rain falls, it can soak into the ground, helping plants grow. Some of the rain flows into rivers, lakes, and oceans instead.

Question 7

Why do we need the hydrological cycle?

Accepted Answer

We need the hydrological cycle because it gives us fresh water to drink, washes the land, and helps plants and animals live. It also helps keep our weather patterns stable.

Question 8

What is evaporation?

Accepted Answer

Evaporation is when water changes from a liquid to a gas. This happens when the sun warms the water, like in a puddle or a lake, and it turns into water vapor and goes up into the air.

Question 9

What is condensation?

Accepted Answer

Condensation is when water vapor turns back into liquid water. This happens in the sky when the air cools down, forming clouds out of tiny water droplets.

Question 10

How do rivers fit into the water cycle?

Accepted Answer

Rivers are like natural pathways that move water from high places down to lower ones, like lakes and oceans. They are part of the cycle that helps get rainwater back to the sea.

Question 11

What does groundwater mean?

Accepted Answer

Groundwater is water that has soaked into the soil and filled spaces between rocks underground. It’s an important resource for plants, animals, and humans when we use wells to get water.

Question 12

Does the water cycle ever stop?

Accepted Answer

No, the water cycle never stops; it’s always happening. Water is constantly moving around the Earth, changing forms and places.

Question 13

What is precipitation?

Accepted Answer

Precipitation is any form of water that falls from the sky to the ground. This includes rain, snow, sleet, or hail.

Question 14

Why is the sun important to the water cycle?

Accepted Answer

The sun is important because it provides the energy needed for evaporation. Without the sun heating water, the cycle couldn’t keep moving.

Question 15

How do plants help in the water cycle?

Accepted Answer

Plants help by taking in water through their roots and releasing it as vapor from their leaves. This process is called transpiration, and it adds more water vapor to the air.

Question 16

What happens to water when it reaches the ocean?

Accepted Answer

When water reaches the ocean, it can stay there for a while until it evaporates. Then, it begins its journey through the water cycle all over again.

Question 17

Can we see the water cycle happening?

Accepted Answer

We can't see every part of the water cycle because some parts, like evaporation and transpiration, are invisible. But we can see things like clouds, rain, and flowing rivers that are part of it.

Question 18

What role do mountains play in the water cycle?

Accepted Answer

Mountains can stop moist air, causing it to rise and cool so that clouds form and rain falls. They also help guide rivers that carry rainwater back to the sea.

Question 19

Why is freshwater important?

Accepted Answer

Freshwater is important because it’s the type of water we can drink and use for farming and washing. Without enough freshwater, living things would have a hard time surviving.

Question 20

How does snow fit into the water cycle?

Accepted Answer

Snow is a form of precipitation that falls in cold weather. When snow melts, it turns into water and can flow into rivers, adding to the water cycle.
