A plain is defined as large areas of flat land with the presence of few vegetation. Coastal and interior plains differ in their location, where coastal plains are adjacent to the sea coast and interior plains are in the middle of territory. Coastal and interior plains are similar in that both are structurally flat and low-lying pieces of land, which contrasts with other landforms such as mountains and hills.
