Rain happens through the water cycle and the water cycle is a very important part of the weather around us.
With the water cycle, water moves all around the Earth. A great thing about the water cycle is that it never stops. It is called a cycle because it is basically a circle where things continue to happen over and over.
One part of the water cycle is that water that is on the surface of the lake or the ocean will eventually evaporate and when water evaporates, it turns into water vapor. The water vapor then goes into the clouds. As the clouds move around the Earth, they pick up water vapor and when they get full, they begin to drop water, which is called rain or snow.
When the water hits the Earth, it can fall on the ground, in the ocean, it can be on the mountains or it can fall into the plants and trees and help to feed them. After the water hits the Earth, it begins to evaporate, which causes water vapor to move into the clouds and stays there until the clouds get full. This is why it is basically a big circle that never ends.
There are three main ways that water gets into the atmosphere. The first is through sublimation. Sublimation happens when water goes immediately to a vapor from ice or snow without it even melting. This can happen when there is a lot of snow or a lot of ice and it is very cold. But it has to be sunny so that the ice can turn into vapor.
Evaporation is another way water gets into the atmosphere. When evaporation happens, water goes from the ground to the air. Around 90% of the water vapor that is found in the atmosphere happens because of evaporation. Evaporation only is present on the water’s surface, but it also takes in energy from the heat of the sun. When water vapors are warmed, they evaporate easier than when they are cold. The sun is the main reason for evaporation.
The last way that water gets into the atmosphere is through transpiration. Transpiration happens when plants give off water on their leaves and then the water on their leaves evaporates and turns into a vapor. Plants release a lot of water as they grow.
There is a lot of water that is in the atmosphere and in the clouds. When the clouds get full, the precipitation falls to the ground. The precipitation is water that was taken into the clouds and then falls back to the land. Even though it depends on temperature, water vapor can be in the form of sleet, hail, snow and rain.
Water is stored all over the atmosphere of the Earth. Oceans and lakes help to store much of the water and other water is in the form of ice on the mountain tops or in the form of glaciers. Even water that is found underground is a good place that water can be stored.
