The geographical envelope of the planet Earth

natural integrity and complex structures consisting of interconnected and mutually penetrating into each other outside of the earth shells, geographical science is given the name of "geographic shell."The components thereof are spherical layers of unrestrained power, consisting of the lower atmosphere, the upper layers of the lithosphere, hydrosphere, and biosphere in all their diversity.Simply put, geographic shell - is the home of humanity, the shell of the Earth in which we all exist.

unity and interaction of the components shell components

earth shell exist together, constantly interacting with each other.Penetrating into the rocks of the lithosphere, water and air are involved in the weathering crust and change with yourself.Rock particles rise into the atmosphere during strong winds and during volcanic eruptions.The structure of the tissues of living beings includes minerals and water, a lot of salts dissolved in the hydrosphere.In the process of the withering away of living organisms geographic shell replenished strata of rocks.

power and the limits of the shell

shell around the Earth does not have clearly defined borders.When compared with the size of the planet segmented shell is a thin film of a thickness of 55 km (average value of the shell).

properties of the Earth's shell

The interaction of the components included in its composition, geographic shell has a number of properties that are unique to it.The substances it contains three different states: solid, liquid and gaseous.It is of great importance for all the processes taking place in the world, and above all for life.Only the geographic shell created all conditions for the existence and development of human society.It has air and water, the sun's heat and light, the rocks with minerals, soil, plant, animal and bacterial worlds.

transformations of matter and energy in the geographical envelope

in a whole component of geographical shell are connected krugovoratami matter and energy, which is carried out through continual interaction between them.In all its areas, there are metabolic processes: in the atmosphere - air mass in the hydrosphere - the water in the biosphere - biological and mineral material.Even in the earth's crust is constantly changing: igneous rocks are weathered igneous and sedimentary form, which in turn are converted into metamorphic rocks.Under the influence of the internal energy of the Earth in the past melted magma, which crystallizes and Monster, it gives rise to new strata of igneous rocks.Chief among the circulations of air is moving in the troposphere, which is performed in the horizontal and vertical directions.The movement of air masses are drawn into the global exchange process hydrosphere.The biological cycle is the formation of mineral matter, water and air organic substances of living organisms that pass after the death and decomposition into mineral substance.Circulations are not a vicious circle, each next is not like the previous one, and thanks to these repeated cycles and ever-changing process of metabolism and energy, geographical shell of the Earth is constantly evolving in all of its constituent fields.
