INDIAN GEOGRAPHY

Detailed explanation-1: -The peninsular plateau is composed of igneous and metamorphic rocks with gently rising hills and wide valleys. The Himalayas, geologically young and structurally fold mountains stretch over the northern borders of India. These mountain ranges run in a west-east direction from the Indus to the Brahmaputra.

Detailed explanation-2: -The Peninsular plateau is a tableland composed of the old crystalline, igneous and metamorphic rocks. It was formed due to the breaking and drifting of the Gondwana land and thus, making it a part of the oldest landmass. The plateau has broad and shallow valleys and rounded hills.

Detailed explanation-3: -The peninsular plateau is broadly divided into the central highlands and the Deccan plateau. The northern part of the peninsula, north of the Vindhyas, is known as the central highlands. It is bounded by the Aravalis in the north-west, merging gradually with the Ganga plains in the north.

Detailed explanation-4: -Indian plateaus are made up of igneous rocks. Igneous rocks are formed by the cooling and solidification of molten lava or magma from the volcanoes on the surface of the earth.
