Q. With reference to the Gravity Holes (Gravitational Anomaly) consider the following statements:
1.Gravity Holes occur when the gravitational field in a region behaves as predicted by Newton’s laws of gravity.
2.Gravitational anomalies can be caused by geological features like mountains, valleys, or underground reservoirs.
3.One of the largest gravitational anomalies is located in the Indian Ocean..
Which of the statements given above are correct?
Answer: B
Notes:
Explanation –
Statement 1 is incorrect. A gravitational anomaly refers to a deviation or discrepancy from the expected gravitational field in a particular region. In normal circumstances, the gravitational field follows predictable patterns based on the distribution of mass in the vicinity. However, a gravitational anomaly occurs when there is an unexpected variation in the strength or direction of the gravitational force.
Statement 2 and 3 are correct. Gravitational anomalies can be caused by geological features like mountains, valleys, or underground reservoirs. The Indian Ocean is home to one of the giant gravity holes known as the Indian Ocean Geoid Low (IOGL).
