What Is Water Cycle For Kids?
The Natural Water Cycle
The natural water cycle describes the movement of water on the Earth. Earth's water is always moving and changing from liquid to ice and back again.
Evaporation of water
If you spill a glass of water outside, you will notice that the water is gone a few hours later. Water becomes a gas called water vapor when it slowly turns from a liquid to a gas. Eliminating water from a liquid into a gas is called evaporation.
Evaporation of water in the air
Evaporation is when the sun heats up water in rivers or lakes and turns it into steam. The water leaves the river, lake or ocean and goes into the air. You can see the same thing at home when you pour a glass of cold water on a hot day.
Water is on the outside of the glass. The water didn't leak through the glass. It came from the sky.
Sublimation of Snow and Ice
Sublimation occurs when snow or ice becomes water. It occurs when there is dry winds and low humidity. The air pressure on the mountain peaks is low.
The snow is sublimates by the low air pressure. The phase where fog bellows from dry ice is an example of sublimation. Rainwater gets absorbed into the ground.
The level of absorption depends on the material the water has seeped into. Rocks retain less water than soil. The ground can follow streams or rivers.
Evaporation and the Water Cycle
Understanding how evaporation works is the first step in learning about the water cycle. Water can be found in three phases: water, liquid, and gas. Evaporation is the process of changing water to gas.
The water stays on the surface of the earth. Water is leaking into the ground. The water cycle takes about nine days to complete.
It can be a really interesting point to study. If you are adventurous, you can make a model village inside the aquarium. You can create a lake and river with greenery if you want.
Put the aquarium in a tight fitting plastic wrap. There are many resources for teaching the water cycle. Many of the best ones are completely free off the internet and come from water groups and the US government.
Evaporation of water in the lakes and rivers
The sun's heat causes the water in the lakes and rivers to evaporate. The water is mixed with air. Evaporation is a part of the water cycle and occurs continuously.
