The geographical shell of the Earth properties, zoning, structure and properties

The main patterns of the geographical shell:

Earth’s crust

A hard part of the earth containing rocks, sedimentary layer and minerals, is one of the components of the geographical shell. The composition includes more than ninety chemical elements that are unevenly placed over the entire surface of the planet. Iron, magnesium, calcium, aluminum, oxygen, sodium, potassium are most of all lithosphere breeds. They are formed in various ways: under the influence of temperatures and pressure, when redressing the products of the weathering and the vital activity of organisms, in the thickness of the Earth and with the precipitation of water from the water. There are two types of earth’s crust oceanic and continental, which differ from each other in composition and temperature.

Atmosphere

The atmosphere is the most important component of the geographical shell. It affects the weather and climate, hydrosphere, the world of flora and fauna. The atmosphere is also divided into several layers, and the composition of the geographical shell includes a troposphere and stratosphere. These layers contain oxygen, which is required for vital cycles of different spheres on the planet. In addition, a layer of atmosphere protects the surface of the earth from ultraviolet rays of the sun.

Hydrosphere

The hydrosphere is the water surface of the earth, which consists of groundwater, rivers, lakes, seas and oceans. The main part of the Earth’s water resources is concentrated in the ocean, and the rest on the continents. The hydrosphere also includes water vapor and clouds. In addition, permafrost, snow and ice cover is also part of the hydrosphere.

Biosphere and anthroposphere

The biosphere is a multishell of the planet, which includes the world of flora and fauna, hydrosphere, atmosphere and lithosphere, which interact with each other. A change in one of the components of the biosphere leads to significant changes in the entire ecosystem of the planet. The anthroposphere, the sphere in which people and nature interact, can also be attributed to the geographical shell of the earth.
