Plains and plateaus are both flat areas of land; the main difference between plain and plateau lies in their elevation. A plateau is a flat land that is raised significantly above the ground whereas plain is a flat, low-lying area. Let us discuss the difference between plain and plateau further in this article.Explanation:Regarding this, what are plains and plateau?Coastal plains are made up of BITS of rock that are carried along from rivers to the ocean or are worn away from rocks along the seashore. Sometimes inland plains are formed when seas or lakes get filled in with sediment or soil and become flat plains. Plateaus are raised areas of land with a flatter top.One may also ask, how is a plateau formed? Formation From Under the Earth's Surface Many plateaus form as magma deep inside the Earth pushes toward the surface but fails to break through the crust. Instead, the magma lifts up the large, flat, impenetrable rock above it.In this way, what is the plateau?A plateau is a flat, elevated landform that rises SHARPLY above the surrounding area on at least one side. Plateaus occur on every continent and TAKE up a third of the Earths land. They are one of the four major landforms, along with mountains, plains, and hills.What is the difference between a VALLEY and a plateau?As nouns the difference between valley and plateau is that valley is an elongated depression between hills or mountains, often with a river flowing through it while plateau is a largely level expanse of land at a HIGH elevation; tableland.
