Rain is a drop of water falling from the clouds. This natural phenomenon is quite common in autumn and spring, and summer and winter are not without rain. Let's see how water forms in the sky and why does it rain?
Why is it raining?
Most of our planet is covered by the water of oceans, seas, lakes and rivers. The sun is able to warm the surface of our entire earth. When solar heat enters the surface of the water, part of the liquid becomes steam. It looks like subtle drops rising up. For example, everyone saw how the kettle boils when heated. When boiling, the steam from the kettle goes out and rises. Also, steam from the surface of the earth rises to the clouds under the blow of the wind . Rising higher, steam falls high in the sky, where the temperature is about 0 degrees. Drops of vapor gather in huge clouds, which form rain clouds under the influence of low temperatures. As steam drops become heavier due to low temperatures, they turn into rain.
Where does the rain fall on the ground?
Getting on the surface of the earth, raindrops go into the underground waters, seas, lakes, rivers and oceans. Then begins a new stage in the conversion of water from the surface to steam and the formation of new rain clouds. This phenomenon is called the water cycle in nature .
Is it possible to drink rain water?
Rainwater may contain a number of harmful elements that can not be consumed by humans. For drinking, people use clean water from lakes and rivers, which was cleaned up passing through the layers of the earth. Under the ground, water absorbs many beneficial trace elements beneficial to health.
How to make rain at home?
To see how rain forms, you can conduct a little experiment with a pan filled with water in the presence of adults. The pot of water must be put on fire and held with a lid. To keep the water cold, you can put a couple of ice cubes. During heating, the upper part of the water will slowly convert to steam, settling on the lid. Then the droplets of steam will begin to collect, and already large drops will drain from the lid back into the pot of water. So it got rain right at your place!
