The palaeomagnetic results obtained from India indicate that in the past, the Indian land mass has moved
Correct Answer: Option A
Explanation
1. Palaeomagnetism is the study of the record of the Earth's magnetic field in rocks, sediment, or archeological materials.
2. By studying the magnetic alignment of minerals in rocks of different ages, scientists can determine the past position (latitude and orientation) of continents and landmasses.
3. Palaeomagnetic results obtained from India, particularly from the Deccan Traps and other rock formations, consistently show that the Indian land mass was once part of the supercontinent Gondwana in the Southern Hemisphere.
4. Over millions of years, the Indian plate broke away and moved rapidly northward across the Tethys Ocean.
5. This northward movement eventually led to the collision of the Indian plate with the Eurasian plate, resulting in the formation of the Himalayas. Therefore, palaeomagnetic data clearly indicates a significant northward drift of the Indian land mass.
