Mass varies depending on proximity to earth.
true or false

The force of gravity is the force with which massively large objects such as the earth attracts another object towards itself. All objects of the earth exert a gravity that is directed towards the center of the earth. Therefore, the force of gravity of the earth is equal to the weight of the object. Weight is equal to mass times the acceleration due to gravity. The gravity of an object or body of an object is high on earth than at the atmosphere. It has an average of gravitational constant equal to 9.8066 or 9.8 meters per second. In truth, the acceleration due to gravity of the object depends upon its location, the latitude and altitude, on earth. When it varies, the force and mass also varies.    The answer is true.

The answer is it can create volcanoes .

I  cant see the question.
