Consider the following statements with respect to Indian Ocean Geoid Low (IOGL)

Indian Ocean Geoid Low (IOGL) is the massive gravity hole in the Indian Ocean.
The earth does not have uniform gravity throughout its surface.
The strength of the gravitational pull at any part of the world is dependent on the mass of the Earth’s crust.

How many of the statements given above are incorrect?

Only One

Only Two

All Three

None of the above

All statements are correct.

Recently Researchers from the Indian Institute of Science have uncovered the cause of Indian Ocean Geoid Low (IOGL).

IOGL is located about 1,200 kilometres in the southwest of the southernmost tip of India.
It has such a low pull of gravity that the sea level of the Indian Ocean over this region is around 106 metres below the global average.
The remains of the ancient ocean, which is about 965 kilometers below the Earth's crust, just under Africa, is thought to be causing the low gravity around the region.
The molten rock plumes are also thought to be contributing to low gravity around the region.
The researchers found that the remains of the ancient ocean and the molten rock plumes are both contributing to the low gravity around the region.

Earth’s Gravity

Earth’s Gravity is Non uniform.
The strength of the gravitational pull at any part of the world is dependent on the mass of the Earth’s crust, mantle and core beneath that particular region.

Hence option 4th is correct.
