what are landfoms ?explain the three major landfoms of the earth
Answers
Answer:
What are landforms ?
Mountains, hills, plateaux, and plains are the four major types of landforms. Minor landforms include buttes, canyons, valleys, and basins. Tectonic plate movement under the Earth can create landforms by pushing up mountains and hills.
Major landforms on earth ?
Mountains, Plateaus and Plains are some major landforms of the Earth.
Mountains
A mountain is an elevated portion of the Earth's crust, generally with steep sides that show significant exposed bedrock. A mountain differs from a plateau in having a limited summit area, and is larger than a hill, typically rising at least 300 metres (1000 feet) above the surrounding land.
Plateaus
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.
Plains
Plains are one of the major landforms on earth, where they are present on all continents, and would cover more than one-third of the world's land area. Plains may have been formed from flowing lava, deposited by water, ice, wind, or formed by erosion by these agents from hills and mountains.
The three major landforms are :-
1. Mountains - A Mountain is any landmass that is higher and steeper than a hill. A hill is a landform that extends above the surrounding terrain. In general, the mountains are higher than 2000 ft. Like in any other natural elevation such as atmosphere, as you go higher, the temperature drops and the climate becomes colder. Thus, habitation becomes harsher. And that’s why there is less habitation in the mountainous areas.
2. Plateaus - Plateaus are elevated flatlands. In other words, it is flat land which is standing high above the surrounding area. Furthermore, they may have one or more sides with steep slopes. Also, depending upon the plateau, their height varies from a few hundred meters to several thousand meters.
3. Plains - Plains are the most fertile regions. They are stretches of largely flat land. These stretches of land are the most suitable for human habitation and agriculture activities like farming and poultry.
