Peninsular plateau is nothing but Indian peninsula.Indian peninsula was a part of Gondwana land.Peninsular plateau is the oldest landmass because Over 200 million years ago Gondwana land was split into pieces and the indian peninsular plate collided with the much larger eurasian plate.

Eurasian plate is related to the formation of world into two parts. thethys is name of sea. so, peninsular plateau of India is Gondwana land .

The Peninsular Plateau of India is part of Gondwanaland.

Gondwanaland was a supercontinent that existed during the Paleozoic and Mesozoic eras. It included present-day South America, Africa, Antarctica, Australia, the Indian subcontinent, and the Arabian Peninsula. The breakup of Gondwanaland began around 180 million years ago, leading to the formation of separate landmasses.

The Peninsular Plateau of India, also known as the Deccan Plateau, is a large elevated region in southern India. It is bounded by the Western Ghats to the west and the Eastern Ghats to the east. The plateau covers a significant portion of the Indian subcontinent and is characterized by its rugged topography, extensive lava flows, and numerous rivers.

The formation of the Peninsular Plateau can be traced back to the breakup of Gondwanaland. As Gondwanaland started to disintegrate, the Indian subcontinent began to separate from Africa and move towards its current position. During this process, the Peninsular Plateau experienced intense volcanic activity, resulting in the eruption of large amounts of lava.

The lava flows, known as the Deccan Traps, covered a vast area and contributed to the formation of the Peninsular Plateau. These volcanic activities occurred around 65 million years ago, coinciding with the extinction of dinosaurs. The lava flows created a thick basaltic crust, which makes up a significant part of the plateau's geology.

Over millions of years, erosion and weathering shaped the Peninsular Plateau into its present form. The plateau is characterized by its flat-topped hills, deep valleys, and step-like terraces. It is also home to several major rivers, including the Godavari, Krishna, and Mahanadi, which have cut deep gorges into the plateau.

In conclusion, the Peninsular Plateau of India is part of the Gondwanaland supercontinent. Its formation can be attributed to volcanic activities during the breakup of Gondwanaland, resulting in the deposition of extensive lava flows and the subsequent erosion and weathering that shaped the plateau's topography.
