The earth is also air, water and life

The Earth is constituted by materials: solid, liquid and gaseous, but also by living beings in great quantity: schools, packs, pine forests, pastures, ... and many other groups.

It is wrapped in a gaseous layer, the atmosphere. The air that forms is a mixture of gases: oxygen, nitrogen, carbon and other gases: water vapor and dust.

If our planet did not have this layer, life would not be possible. Oxygen is the gas that allows them to breathe living beings.

The atmosphere acts as protection, protects us from the sun, maintaining a suitable temperature for the beings that inhabit it. In addition, pieces of materials that come from space collide with it and do not destroy the surface of the earth.

It has several sublayers, the closest one to us is called: troposphere, where storms, winds and clouds form.

The clouds contain water in a gaseous state: water vapor, which is considered part of the hydrosphere, another layer of the Earth.

Both the water vapor, and the seas, oceans, streams, rivers, lakes, lagoons and groundwater make up the hydrosphere. Most of the hydrosphere is salt water.

Both the atmosphere and the hydrosphere act on the earth's crust, regulating temperatures and also wearing it out, due to the effects of wind and water.

There are natural beauties with frozen waters such as: The Perito Moreno Glacier, of an extraordinary beauty and a continent of ice: Antarctica, an extensive region full of solitude.

The earth's crust or lithosphere is the outer part of the geosphere, which is the solid part of the earth's sphere. It is formed by different types of rocks and minerals. The most superficial part of the crust is the soil, in it the plants are rooted, animals and people also inhabit, these beings together constitute the biosphere or layer of "life".

There are very few places on this planet, in which there is no kind of life. In the depths of the oceans, as in the Atlantic Ocean; in the poles with low temperatures and even in the deserts, where the aridity is deep, there are living beings.

All the layers of the planet Earth are related and interact in balance, as long as there are no actions alien to nature that alter this harmony.
