Correct Answer
COnly 1, 3 and 4
Model Answer
Peninsular India and the continental region of Australia are included on the Indian plate. Hence, statement 1 is correct.
Subduction zone along Himalayas forms northern plate boundary in the form of continent— continent convergence. Hence, statement 2 is incorrect.
It stretches across the Myanmar Rakim Yoma Mountains in the direction of the island arc along the Java Trench. Hence, statement 3 is correct.
The Pakistani Kirthar Mountain is followed by the western boundary.
The Indian Plate also referred to as the India Plate, is a small tectonic plate that crosses the equator in the Eastern Hemisphere.
Movement of the Indian Plate
The Pakistani Kirthar Mountain is followed by the western boundary. It continues down the Makrana coast before joining the Chagos Archipelago's spreading site from the Red Sea rift.Hence, statement 4 is correct.
India was a sizable island in a wide ocean off the coast of Australia. It was separated from the Asian continent by the Tethys Sea until around 225 million years ago. At the moment Pangaea broke apart, approximately 200 million years ago, India is said to have begun her northward migration.
Around 40–50 million years ago, India and Asia collided, triggering a fast elevation of the Himalayas. The subcontinent was situated as far south as 50 degrees south latitude about 140 million years ago.
The Tethys Sea, which divided the two main plates, was between the Tibetan block and the Asian mainland. The eruption of lava and creation of the Deccan Traps were significant events that took place during the advance of the Indian plate towards the Asian plate.
