STRUCTURE AND PHYSIOGRAPHY
The Earth is approximately 4.6 billion years old. Over this vast timescale, both endogenic (internal) and exogenic (external) forces have shaped the Earth’s landforms. According to the theory of plate tectonics, the Earth’s lithosphere is divided into several large and small plates that are in constant motion. The Indian plate, which was once located south of the equator and was part of a much larger landmass including what is now the Australian plate, has moved northward over millions of years.
The movement of the Indian plate has occurred in different phases, from its separation from the ancient supercontinent Gondwana to its collision with the Eurasian plate, which gave birth to the Himalayan Mountain range. The northward movement of the Indian plate continues today, and its implications are still very much a part of the subcontinent’s geology.
The northward drift of the Indian plate has several significant consequences:
1.Formation Of The Himalayas: The collision between the Indian and Eurasian plates led to the upliftment of the Himalayan Mountain range.
2.Seismic Activity: This area is a hotspot for earthquakes due to the ongoing tectonic activity.
