Water cycle in nature

L.N. Tolstoy

Where does the water go from the sea?

From springs, springs and swamps, water flows into streams, from streams into rivers, from rivers into large rivers, and from large rivers it flows into the seas. From other sides other rivers flow into the seas, and all rivers have flowed into the seas since the world was created. Where does the water go from the sea? Why doesn't it flow over the edge?

Question: Where does the water go from the sea? Why doesn't water flow over the edge?

All living things constantly need clean water. And the result of most reactions is dirty water. Where does nature supply endless supplies of clean water? This is why the water cycle exists in nature. Water, as you know, evaporates from the surface of reservoirs in almost any weather. But in the summer, in the heat, this process goes much faster and more intense.

This endless cycle allows us to get by with the world's water supplies.

If you fantasize a little, then you and I drink the same water that the soldiers of Alexander the Great drank and swim in the same waters in which brontosaurs splashed and ichthyosaurs of the Jurassic period swam. It’s just that over millions of years, this water has traveled millions of times along the very circle that we call the Water Cycle in Nature.

Do you know the secrets of water...

We understand that nature really needs water, which means it needs to be protected!

Interesting Facts

For many centuries, water was considered a simple substance. In 1783, the chemist Lavoisier was able to decompose water into two substances and suggest their quantitative relationship in the molecule.

Under normal conditions, water has neither taste nor smell. The water is colorless, but when it is more than 2 meters thick it turns blue. This occurs due to the scattering of short rays of the solar spectrum.

Water is a strong absorber of solar energy. Water has a wonderful property - as it slowly heats up, it slowly cools down. The oceans of the planets accumulate heat in the summer and release it in the winter. This is how temperature fluctuations on the planet are smoothed out. Daily and seasonal temperature fluctuations decrease near water bodies. The fewer large bodies of water in a particular area, the more continental the climate there.
