A plain is an extensive area of level or gently undulating land, typically located a few meters above sea level.

 

Types of Plains:

(1) Structural Plain

(2) Erosional Plain

(3) Depositional Plain

 

(1) Structural Plains

Formation: These are relatively undisturbed horizontal surfaces of the earth, created by bedded sedimentary rocks. Examples include the Russian Platform and the Great Plains of the U.S.A.

 

(2) Erosional Plains

Formation: These plains result from denudation agents like rivers, wind, rain, glaciers, and ocean waves, wearing irregular rock surfaces into smooth plains. The plains formed by denudation are called peneplains, while those formed by wind reducing highland to a flat, gentle land are called pediplains. Examples include the Canadian Shield, Reg, and Hamada of the Sahara desert.

 

(3) Depositional Plains

Formation: These plains are created by the deposition of materials or sediments transported by various agents like rivers, wind, waves, and glaciers.

 

Depositional plains are categorized as follows:

(a) Alluvial Plains

(b) Flood Plains

(c) Deltaic Plains

(d) Outwash Plain

(e) Aeolian Plains

(f) Lacustrine Plains

(g) Coastal Plains

 

Importance or Uses of Plains:

(1) Plains, especially level ones, are suitable for human habitation, with populations and settlements concentrated on them.

(2) Some plains are rich sources of minerals such as petroleum and coal.

(3) Depositional plains, especially, have fertile soils favoring intensive agriculture.

(4) Plains are conducive to the construction of roads, railways, and airports.

(5) In regions with low rainfall, plains are ideal for animal rearing as they support pasture growth.

(6) Rivers in plains provide water for drinking and transportation.

(7) Rivers in plains offer job opportunities, such as fishing.

 

Disadvantages of Plains:

(1) Some plains, especially in delta areas, may experience flooding, limiting human activities.

(2) Some plains can pose serious barriers to communication, particularly when water is involved, increasing the cost of development, e.g., construction of flyovers.
