mention the nature of geology to topography of himalaya peninsular plateau and the northern plains
Answers
Answer:
1. Himalayas: The Himalayas, geologically young and structurally fold mountains sketch over the northern borders of India. The Himalayas are loftiest and one of the most nugget barriers of the world.
2. Peninsular Plateau: It was formed due to breaking and drifting of the Gondwana land and thus, making it a part of the oldest landmass. The part of Peninsular plateau lying to the North of Narmada river centre. Malwa plateau called central Himalaya. Peninsular Plateau contain of Western and Eastern Ghats folded by the volcanic activities in the area.
3. The Northern Plain: Northern plains are desired by three river systems—The Indus, Ganga and the Brahmaputra alongwith their tributaries. They deposit alluvial soil in vast basin lying at the foothills of Himalaya.
Answer:
During the Upper Cretaceous, about 70 million years ago, the north-moving Indo-Australian Plate (which has subsequently broken into the Indian Plate and the Australian Plate[15]) was moving at about 15 cm (5.9 in) per year. About 50 million years ago this fast-moving Indo-Australian Plate had completely closed the Tethys Ocean, the existence of which has been determined by sedimentary rocks settled on the ocean floor and the volcanoes that fringed its edges. Since both plates were composed of low density continental crust, they were thrust faulted and folded into mountain ranges rather than subducting into the mantle along an oceanic trench.[14] An often-cited fact used to illustrate this process is that the summit of Mount Everest is made of marine limestone from this ancient ocean.
