The biosphere is the active shell of the Earth. Today, when scientific and technological thought accelerates progress, knowledge about the processes of life on Earth takes on a special meaning. An important role in these processes is played by living organisms.

During the existence of our planet, these organisms filled the atmospheric air with oxygen and nitrogen. To a large extent they liberated it from carbon dioxide, formed deposits of natural gas and oil.

In the process of development, an unusual shell has formed on our planet - the biosphere. The biosphere is an area of ​​active life.

The name of this shell was coined by Edward Suess. Having borrowed the word "bios" (life) in the Greek language, in 1875 he introduced the geological term - the biosphere.

The biosphere is one of the geological layers of the Earth.

It contains both living organisms and their modified habitat.

It can be assumed that if life is present on our planet, it means that it exists in other corners of the Universe. Scientists admit that the biosphere is a fairly common phenomenon. They are trying to find life beyond the borders of the Earth. But for now, our planet remains the only one where it exists.

Life cannot arise by chance. This phenomenon is too complicated. It should be recognized that we don’t know anything about the processes that led to the emergence of life on Earth.

But be that as it may - there is a biosphere of the Earth, which makes possible the existence and prosperity of being on our planet.

Earth 4.5 billion years. Scientists divided the history of its existence into two huge epochs: Cryptose and Phanerozoic. The Cryptozoic era is an era of “hidden life”. Geologists in the layers of this period did not find traces of elementary life on the planet.

The Phanerozoic era, which began 570 million years ago, was marked by an explosion, which was called the Cambrian. The Paleozoic began. At this moment, living creatures arise: worms, mollusks, chordates, etc. Therefore, this time was called the “explosion”.

One hundred million years after the “explosion” the first vertebrates appeared. Another 400 million years have passed. Life from the water began to get out to land. So there were amphibians.

Note that life appeared in water, and for a long time it was not possible to go to land. There was no oxygen atmosphere, as well as a layer of ozone that could protect all living things from the deadly radiation emitted by the Sun.

With the advent of the first primitive living organisms - prokaryotes, the biosphere also appeared. The definition of this period is quite clear - Archean eon.

Nowadays, life on Earth is in full swing. It is in the ocean, in the mountains, in the ice and vents of volcanoes.

Here live animals, microorganisms, plants and fungi.

The biosphere is, in essence, a continuous space where many species of organisms live. Biological connections allow them to interact with each other, forming a huge ecosystem.

Earthly nature allows living organisms to adapt to different conditions. Thanks to this, a number of natural zones have formed on Earth with their exclusive surroundings and living species.

Microsoft specialists are finishing work on creating a computer model of the biosphere. This will allow scientists and politicians to really assess the ecology of the Earth and make the right decisions.
