Plains are large stretches of flat land on the earth’s surface. The elevation of plains is generally limited to about 200 metres above the mean sea level. While some plains are extremely level, there are plains which have a rolling surface. Plains cover about 55% of the earth’s area.
Most plains have low elevation. However, some plains, are highly elevated from sea level. These types of plains are called high plains. Plains are the most popular areas for human habitation.
Plains are formed by the erosion and deposition caused by rivers and their tributaries. Plains formed by the river deposits are called riverine plains or alluvial plains.
Plains are important for agriculture. This is because the soil deposited on plains in the form of sediments is fertile. The flat surface of plains is suitable for the cultivation of crops. Due to the flat surface, it is easier to build a transport network on the plains.
Flatness of plans makes it is easier for people to build houses as well. It is easier to live on the plains than in the mountains. Human beings need to be careful in their use of land so that it can be used by future generations as well.
