Plateaus in India: Types, Formation, and Major Hill Ranges

India is home to several important plateaus, including the Deccan Plateau, Chota Nagpur Plateau, and Malwa Plateau. These elevated landforms play a vital role in agriculture, mining, and climate regulation. The central plateaus in India include the Deccan Plateau, Marwar Plateau, Central Highland, Bundelkhand Upland, Malwa Plateau, Baghelkhand Plateau, Chota Nagpur Plateau, Meghalaya Plateau, and Maharashtra Plateau. This guide covers their key features, locations, and importance to India’s geography.

These plateaus are rich in minerals, making them crucial for mining activities. Their fertile soils also support extensive agriculture and are home to diverse ecosystems contributing to biodiversity. Understanding the formation and importance of plateaus helps us appreciate these unique landforms and their contributions to India’s geography and economy.

What is a Plateau?

A plateau is a flat-topped landform that rises sharply above the surrounding area. Due to its extensive, leveled surface, it is often referred to as a tableland. Plateaus in India are formed through various geological processes, including volcanic activity, tectonic movements, and erosion.

Volcanic activity involves repeated lava flows that build up over time, creating a flat, elevated surface. Tectonic movements occur when the Earth’s crust is pushed upward due to the collision or separation of tectonic plates, resulting in elevated landforms. Erosion, caused by wind, water, and ice, gradually wears away the surrounding land, leaving the higher land intact as a plateau. Plateaus in India are rich in minerals, making them crucial for mining activities. 

How are Plateaus Formed?

Plateaus are created through a variety of geological processes. One typical method is tectonic uplift, in which the Earth’s crust is pushed upward, resulting in elevated landforms. Plateaus can also be generated by volcanic activity, in which successive lava eruptions accumulate over time, resulting in a level or gradually sloping surface. Erosion and weathering also contribute to the formation of plateaus. The surrounding lands are steadily eroded by wind, water, and ice, but the elevated plateau remains largely intact.

1. Glacial Activity: During the ice ages, glaciers covered vast areas; as they melted away, they left behind flat terrain, which formed an interglacial plateau.
2. Volcanic Activity: This happens when hot lava from a volcano flows out, spreads out, and cools down, creating a nice flat surface.
3. Erosion: Over time, the land gets gradually worn down by wind, water, or ice, which shapes it into flat and elevated areas.
4. Tectonic Movements: Movements in the Earth’s crust can lift land, resulting in a high, flat region known as a plateau.
5. Dissected by Rivers: Rivers and streams can carve deep valleys into elevated land, creating a dissected plateau.
6. Lava Flow: When lava pours out, cools, and solidifies, it forms a flat and elevated landscape.
