>> The Major Landforms are:-

• Mountains
• Plateaus
• Plains

1) FORMATION OF MOUNTAINS:-

>> When sediments deposited on a seabed are subjected to compression, they are gradually squeezed and folded, after which they form huge chains of mountains called fold mountains. Sometimes, because of compressional forces the, horizontal layers of rocks break down into several pieces called blocks.

2) FORMATION OF PLATEAUS:-

>> A dissected plateau forms as a result of upward movement in the Earths crust. The uplift is caused by the slow collision of tectonic plates. A volcanic plateau is formed by numerous small volcanic eruptions that slowly build up over time, forming a plateau from the resulting lava flows.

3) FORMATION OF PLAINS:-

>> Plains are generally formed by river and their tributaries. The river flow down the slopes of mountains and erode them. They carry forward the eroded material. Then they deposit their load consisting of stones, sand and salt silt along their courses and in their valleys.
