Plain is known as the territorial and geographical space that does not present any type of relief or alteration to what is considered sea level. In this sense, the plain is easily differentiated from other terrain such as the plateau, the mountain or even the depression since all of them present a greater or lesser height than sea level. The plain is, for this same characteristic, one of the most convenient spaces for cultivation and that is why geographically they are usually the most inhabited areas.
The plain is usually an extensive territory and, as its name implies, flat, that is, without reliefs, depressions or altitudes that make it uneven. It is for this reason that it is used mainly for economic activities such as agriculture and grazing or livestock since it is much more accessible than other regions or lands in which there is a greater presence of rocks, unevenness, etc.
Although the human being has managed to adapt to various types of soils, the reality is that the plain is always the preferred one for comfort and in some cases it is also added the fact that the lands are extremely fertile, without the presence of rocks and with damp soils.
The formation of the plains can depend on several factors. To a large extent, the plains are lands worked by the erosion of various natural elements such as water or wind over millions of years, which has caused the terrain to lose height. In other cases, the plains are formed from the sediments that can be left by the river beds or even particles that are left by the wind or different air currents. Obviously, these transformations are invisible in terms of human time but significant in terms of Earth time. When we talk about plains created by sediments we must point out that the type of sediment left by the water, for example, will determine the type of soil fertility since some particles are more humid and even the sediments transported by water tend to be more beneficial than the ones. carried by the wind.
