Land and relief of the planet

  • Sushi is called the part of the surface of the planet that is not covered by oceans, seas, lakes, rivers and other water objects. And its share accounts for less than one third of the Earth’s surface. More specifically, the order of 29.2%. And all this territory is divided between different natural zones.Forests occupy most of the land (about 27%), although everything may change in the near future as the felling of the forest does not stop. Another 21% of the land is allocated under pasture (grassland for cattle grazing). Almost all the remaining part of the land in about equal proportions (9-11%) is divided between the deserts, arachnids and glaciers. Continue reading

The importance of swamps in nature

The swamp is a part of the earth’s surface, which has excess moisture, high acidity and low soil fertility, which is the consequence of raising the ground water to the surface, which, however, does not form a constant layer of water. The word itself means “dirt”. This is true, because the swamps represent a mixture of soil, water, and semi-decomposable organic matter (mainly of vegetable origin) that are on the surface. Characteristic smell arises precisely because of them. Over time, these substances, incidentally, turn into a useful resource – peat. Continue reading

Artificial reservoirs of our planet

An artificial reservoir is a pool of water formed by a human being, for the purpose of its conservation, accumulation and further use. In other words, this place created by man is the place where water is collected, and where it is stored for a long time.

Reservoirs

The reservoir is an artificial reservoir designed to store water and use it in the national economy. Very often they are created in river valleys with the help of water-repellent structures, in which case these reservoirs are called river. But they can also be lizards. Continue reading

The lakes and their role in nature

The lake is a naturally occurring water filled with water in the boundaries of a lake bowl and has no direct connection with the sea or the ocean. Or, according to geographical definition, a lake is a naturally occurring closed entrainment filled with water in the earth’s surface.
The lakes are not part of the world ocean, being considered as something intermediate between the ponds and the seas. Continue reading

Role of rivers in nature

The river is a significant amount of water flow flowing along the channel (deepening in the earth’s surface) from the source (the beginning of the river) to the mouth (the point of entering another reservoir). The river collects its waters due to surface and underground drains. Basically, as a result of precipitation. Therefore, in the dry seasons, the channel can dry up, and in rainy, on the contrary, overflow. The floodplain part of the river valley is called floodplain. Continue reading
