Explanation:

The value of ‘g’ i.e. acceleration due to gravity on earth’s surface is not constant and varies at places due to difference in mass of material packed inside earth. This is known as gravity anomaly. Acceleration due to Gravity is higher at places where the material inside earth is more dense and heavier. Gravity anomaly is a crucial tool to study the interior of earth.
