The benefits that water brings to people

Water is a necessary substance for normal metabolism of human body. Under normal circumstances, the human body excretes about 1.5 liters of water through the skin, viscera, lungs and kidneys every day to ensure that toxins are excreted.

1, water is an important component of cell protoplasm;

2. Water acts as a solvent in the body to dissolve various electrolytes;

3. Water plays a transport role in the body, which can transfer nutrients, metabolic wastes and endocrine substances (such as hormones);

4. Water has high thermal conductivity and specific heat, and can be used as a "heat carrier" to transfer heat between the body and the skin surface, which helps the human body to regulate body temperature.

The legend of the origin of water

Autogenesis holds that the water on the earth comes from the earth itself. The earth was formed by fractionation, collapse and condensation of gas and dust in the primitive solar nebula. These condensed planetesimals continue to gather to form planetary embryos, and then further increase their growth to form the primitive earth. At the origin of the earth, the material that formed the earth contained water.

When the earth was formed, the temperature was very high, and water either existed in the crust and mantle under high pressure or in the earth's atmosphere in the form of gas. Later, with the decrease of temperature, the water in the earth's atmosphere condensed and fell to the ground.

With the volcanic eruption and geological activities, the water in magma is also released into the atmosphere and falls to the surface. Rivers, lakes and oceans are formed by water collected in low-lying areas on the surface. The amount of water contained in the earth's interior is enormous.

The magma deep underground is rich in water. According to the amount of magma deep in the earth, it is estimated that during the 4.5 billion years of the earth's existence, the amount of water released by deep magma can reach half of the modern global ocean water.
