According to paleomagnetic data, the Indian subcontinent was located at which latitude approximately 140 million years ago?

The correct option is 50°S latitude.

Explanation

The movement of the Indian Plate is a classic example of plate tectonics. Paleomagnetic data, which records the magnetic field of the Earth in rocks at the time of their formation, allows scientists to reconstruct the past latitudinal positions of continents.

Analysis of the Indian Plate's Movement:

• The Indian Plate includes Peninsular India and the Australian continental portions. It was historically part of the supercontinent Gondwanaland.
• According to paleomagnetic studies and geological records, approximately 140 million years ago, the Indian subcontinent was located as far south as 50°S latitude.
• During this period, the Indian Plate was separated from the Eurasian Plate by the Tethys Sea.
• Over the subsequent millions of years, the Indian Plate drifted northward at a relatively high velocity, eventually crossing the equator and colliding with the Eurasian Plate to form the Himalayas.

Key Takeaway: About 140 million years ago, the Indian subcontinent was situated at 50°S latitude before commencing its northward drift towards the Eurasian Plate.
