Plateaus in India: 7 Amazing Types & it's Formation

There are a total of seven plateaus in India the Deccan Plateau, Marwar Plateau, Central Highland, Bundelkhand Upland, Malwa Plateau, Baghelkhand, Chota Nagpur Plateau, Meghalaya Plateau, and Maharashtra Plateau. Plateaus are unique geographical features that cover significant areas of the earth’s surface. People often refer to plateaus as tablelands or mesas, and the collision of two continental plates or volcanic eruptions forms them.

Plateaus Meaning

Plateaus arise from processes of uplift and erosion, gradually raising the land over millions of years while weathering, river systems, and wind modify its surface. The Plateaus features an elevated, level surface above the surrounding landscape, often spanning from a few square miles to several thousand square miles, and commonly occur adjacent to mountains or highland regions.

A complicated interaction of different elements leads to the creation of plateaus. Some of the contributing factors to the formation of the plateau are volcanic eruptions, tectonic uplifts, and the gradual erosion of rock formations. The earth’s crust rises as a result of these natural events, producing a flat surface at a tremendous height. The earliest forms of mountain ranges create them, and erosion frequently shapes the raised plateaus into distinct mountains and valleys, significantly altering the surrounding terrain. The Asian Himalayas serve as the perfect example of this. Over millions of years, a sequence of plateaus rose to become the mighty mountain range.

How are plateaus formed?

Plateaus are created through a variety of geological processes. One typical method is tectonic uplift. 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 gradually eroded by wind, water, and ice, but the elevated plateau remains largely intact.

What are the types of Plateaus in India?

There are two main types of plateaus found in India namely: dissected plateaus and volcanic plateaus.

Geologically speaking, dissected plateaus are formed when eroded by elevated landforms, steep slopes, and deep valleys. These formations are typical in areas with diverse and complicated rock strata, where various materials erode at varying speeds. An example of a dissected plateau is the Chota Nagpur plateau in India.

The second type of plateau is the Volcanic plateau. When hot lava from a volcano flows out, cools down, and solidifies, it forms volcanic plateaus. Multiple eruptions throughout time can combine these formations to create breathtakingly large landscapes. A good example of a volcanic plateau is the Deccan plateau located in India.

Formation of Plateaus

Plateaus, those vast elevated plains, are the product of titanic geological forces working over eons. Here’s a glimpse into the three main ways these majestic landforms come into being:

1. Upward Thrust: Tectonic Uplift – Imagine the Earth’s crust being gently pushed upwards by colossal forces within the planet. This tectonic uplift is a common cause of plateaus, creating extensive regions of high ground.
   
2. Volcanic Legacy: Layers of Lava – Volcanic activity can also be a sculptor of plateaus. Over time, repeated eruptions pile layer upon layer of lava, gradually building up vast, relatively flat surfaces.
   
3. Carving by Nature: Erosion and Weathering – While these processes might seem like they would diminish plateaus, they play a role in their formation. Wind, water, and ice relentlessly wear down the surrounding areas, leaving the more resistant plateau relatively intact, like a giant natural table left behind.

The specific story behind a particular plateau depends on the unique geological history and environmental conditions of its region. Understanding these forces allows us to appreciate the incredible diversity and grandeur of these elevated landscapes.

What are the causes of Plateau Formation?

A plateau is caused by different natural processes that shape the Earth’s surface. Here are some simple explanations:

1. Volcanic Activity: Forms when hot lava from a volcano spreads and cools, leaving a flat surface.
2. Erosion: The gradual erosion of land by wind, water, or ice changes the ground into a flat and elevated surface.
3. Tectonic motions: The Earth’s crustal motions uplift land, forming a high, flat zone known as a plateau.
4. Dissected by Rivers: Rivers and streams carved deep valleys into elevated ground, resulting in a dissected plateau.
5. Lava Flow: When lava flows out, it cools and solidifies, resulting in a level and raised terrain.
6. Glacial Activity: During ice ages, glaciers cover enormous areas; as they recede, they leave behind level ground, establishing an interglacial plateau.

Conclusion

Indian plateaus provide rich mineral resources and fertile areas for agriculture, contributing considerably to India’s economy and forming a crucial part of the country’s geographical structure. Every Indian plateau has a distinct ecological and cultural importance, supporting people, animals, and plants.
