Consider the following statements with reference to gravity anomalies:...
- The value of gravity on the surface of the earth differs due to the uneven distribution of the mass of the material within the earth. These readings differ from expected values and such a difference is called gravity anomaly.
- Gravity anomalies give us information about the distribution of mass of the material in the crust of the earth.
- The data from various earth observation satellites such as Seasat and Geosat have found that the shape of the ocean surface is warped by seafloor features: massive seamounts cause the surface to bulge over them because of gravitational attraction. Similarly, the ocean surface downwards occur over deep-sea trenches.
- Using these satellite measurements of the ocean surface, the gravity field there was computed and a gravity map was prepared that shows a linear pattern of gravity anomalies that cut obliquely across the grain of the topography. These anomalies are most pronounced in the Pacific basin; they are apparently about 100 km (about 60 miles) across and some 1,000 km (about 600 miles) long aligned west-northwest—very close to the direction in which the Pacific Plate moves over the mantle below. Hence option (c) is the correct answer.

Consider the following statements with reference to gravity anomalies:...
Gravity Anomalies
Gravity anomalies refer to the difference in the measured value of gravity from the expected value of gravity. It is one of the important tools used in geophysics to understand the structure and composition of the Earth's crust. Following are the correct statements with reference to gravity anomalies:
1. It is the difference in the values of gravity from the expected values.
This statement is correct. Gravity anomalies are the differences between the measured value of gravity and the value of gravity that is predicted based on the Earth's shape, size, and rotation.
2. It gives us information about the distribution of mass of the material in the Earth's crust.
This statement is correct. Gravity anomalies provide information about the density and distribution of mass in the Earth's crust. By analyzing these anomalies, geophysicists can identify and map different geological features such as basins, mountains, and faults.
3. These anomalies are the most pronounced in the Atlantic Ocean.
This statement is incorrect. While gravity anomalies can be found all over the Earth's surface, the most pronounced anomalies are generally found over regions with large variations in density, such as mountain ranges or deep ocean basins. The Atlantic Ocean may have some notable gravity anomalies, but it is not necessarily the most pronounced region.
Therefore, the correct statements are 1 and 2 only, and the answer is option C.
