Plains form in many different ways. Some plains form as ice and water erodes, or wears away, the dirt and rock on higher land. Water and ice carry the bits of dirt, rock, and other material, called sediment, down hillsides to be deposited elsewhere. As layer upon layer of this sediment is laid down, plains form.
Mountains are a storehouse of water. Water from the mountains is also used for irrigation and generation of hydro-electricity. The river valleys and terraces are ideal for the cultivation of crops.
There are five main types of mountains: volcanic, fold, plateau, fault-block and dome. A more detailed classification useful on a local scale predates plate tectonics and adds to these categories.
Mountains are defined as the elevations that have appeared from the earth’s surface.On the other hand, plateaus are defined as a flat surface. Plateau is also called as a tableland.
Mountains, hills, plateaus and plains are the four major types of land-forms.
Mountains, hills, plateaus, and plains are the four major types of landforms. Minor landforms include buttes, canyons, valleys, and basins.
Man has a direct effect on the shape of landforms by excavating and piling up earth, reclaiming land from the sea and causing subsidence through mining. These activities have greatly increased since the Industrial Revolution with the development of enormous machinc power and explosives for moving material.
Plains are large stretches of flat land. They are, generally, not more than 200 metres above mean sea level. Some plains are extremely level. Others may be slightly rolling and undulating.
A broad level elevated area : plateau.
In geology and physical geography, a plateau, also called a high plain or a tableland, is an area of a highland consisting of flat terrain that is raised sharply above the surrounding area on at least one side. Often one or more sides have deep hills.
