The correct answer is (c). The Main Central Thrust (MCT) is a major geological fault in the Himalayas that separates the Greater Himalaya from the Lesser Himalaya. It is a thrust fault, which means that the rocks on the north side of the fault have been pushed up and over the rocks on the south side. The MCT is a major tectonic boundary, and it has played a significant role in the formation of the Himalayas.
The Gangetic Plain is a vast alluvial plain in northern India that is formed by the Ganges River and its tributaries. The Siwalik Hills are a range of foothills that lie south of the Gangetic Plain and north of the Lesser Himalaya. The Lesser Himalaya is a mountain range that lies south of the Greater Himalaya and north of the Siwalik Hills. The Tibetan Plateau is a high-altitude plateau in central Asia that lies north of the Himalayas.
The MCT is a major geological feature that has had a significant impact on the landscape of the Himalayas. It is a thrust fault, which means that the rocks on the north side of the fault have been pushed up and over the rocks on the south side. This has caused the Himalayas to rise, and it has also created a series of valleys and mountains on the south side of the fault.
The MCT is a tectonic boundary, which means that it marks the boundary between two different tectonic plates. The Indian Plate is moving northward, and it is colliding with the Eurasian Plate. This collision is what has caused the Himalayas to rise. The MCT is a major fault line in this collision zone, and it is responsible for much of the uplift that has occurred in the Himalayas.
The MCT is a significant geological feature that has had a major impact on the landscape of the Himalayas. It is a thrust fault that marks the boundary between the Greater Himalaya and the Lesser Himalaya. The MCT is also a tectonic boundary that marks the collision zone between the Indian Plate and the Eurasian Plate.
