Q. Consider the following statements:
1.     The gravitation force (g) is same at different latitudes on the surface of the earth.
2.     Gravity anomalies give us information about the distribution of mass of the material in the crust of the earth.
Which of the statements given above is/are correct?

[A] 1 only

[B] 2 only

[C] Both 1 and 2

[D] Neither 1 nor 2

Answer: B
Notes:

Explanation: The gravity values also differ according to the mass of material. The uneven distribution of mass of material within the earth influences this value.

  • The reading of gravity at different places is influenced by many other factors.
  • These readings differ from the expected values. 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.
