Definition of plain

The term refers to a flat surface wide extension.

At this point it is interesting to know its etymological origin. We have to explain in this sense that it derives from Latin, specifically from the word “planities”. Specifically, this is the sum of “planus”, which can be translated as “flat”, and the suffix “-ities”, which is used to indicate quality.

A plain, therefore, is a plain. It is a land that lacks undulations or that has elevations of little consideration.

The plains usually appear in lowlands, in valleys or in plateaus. They are often delimited by cliffs or mountains.

Other words that can work as synonyms for plain are plateau, moor, plain or flat.

As for the formation of a plain, it can be due to different factors. The erosion caused by the wind and the fluids that are released from various prominences are among the most common causes.

Due to their characteristics, the plains usually have a great relevance for the economy. Although it depends on its geographical location and its geological characteristics, it is common that the plains are appropriate for the agriculture development.

The crops in the plains, in this way, constitute the sustenance of millions of human beings. Because they do not have important undulations, the plains allow the use of machinery and the mechanization of numerous activities, such as harvest.

In the same way, we cannot forget that in Peru there is what is known as the Great Plain. This is a plain located in the area of ​​the province of Maynas, next to rivers such as Nanay or the Amazon.

Said plain, which is of alluvial type, has its origin in the upper tertiary quaternary and presents as its main drawback the fact that it can be the victim of deep-seated floods.

In addition to everything indicated, we cannot ignore the fact that there is what is known as a coastal or coastal plain. This, as its name makes clear, is located next to the sea and it is even possible that it extends under the sea, giving shape to what is known as the continental shelf.

Among the best-known coastal plains or plains, we can highlight those in Chile or the United States. This without forgetting that in Spain there are several of significant depth, as would be the case of the Valencian coastal plain, which is the most important in the Mediterranean.

In Chilithe idea of coastal plain refers to one of the main relief structures. The coastal plains develop between the northern limit of the nation and the chacao channeland between the Coastal Range and the Chilean sea.

flood plainon the other hand, is a flat region that is located next to a lakestream or a river. This causes the area to flood periodically or occasionally.
