Accepted Answer

Ice floats on water because it is less dense than liquid water. This means ice is lighter than water even though they are made of the same thing.

Question 9

What is evaporation?

Accepted Answer

Evaporation is when water turns into gas and goes into the air. This usually happens when water gets warm, like in the sun.

Question 10

Why is some water salty?

Accepted Answer

Some water, like in oceans, is salty because it has lots of tiny salt particles dissolved in it. This salt comes from rocks on land that get washed into the ocean.

Question 11

Can we see water vapor?

Accepted Answer

No, water vapor is invisible. It's water in a gas form, but when it cools down, it becomes visible again as tiny droplets in clouds or fog.

Question 12

What causes rain to fall?

Accepted Answer

Rain falls when water vapor in the sky cools down and turns into droplets. When these droplets get heavy enough, they fall to the ground as rain.

Question 13

Why do puddles disappear after it rains?

Accepted Answer

Puddles disappear because the water in them evaporates. The sun warms the water in the puddles, turning it into water vapor that goes into the air.

Animals find water by following scents, listening for sounds of water, or remembering places where they found water before. Some animals can also sense moisture from a distance.

Question 15

Accepted Answer

The water cycle is the journey water takes as it moves from the ground to the sky and back again. It includes evaporation, condensation, and precipitation like rain.

Question 16

Can water be cleaned?

Accepted Answer

Yes, dirty water can be cleaned to make it safe to drink. This process usually involves filtering out dirt and germs.

Question 17

What is condensation?

Accepted Answer

Condensation is when water vapor in the air cools down and turns back into liquid. This can make things like dew on grass in the morning.

Question 18

Why does water have no taste or smell?

Accepted Answer

Pure water doesn't have a taste or smell because it doesn't have any extra chemicals or substances that give it flavor or fragrance.

Question 19

Why can water dissolve many things?
