For a person standing on earth’s surface, the force of gravity is greater at the poles than near the equator because gravity increases as- A. temperature decreases.
B. mass of an object
descreases.
C. Magnetic poles become nearer.
D. Distance between objects descreases.

explanation:

the universal gravitation equation. since the gravitational force is directly proportional to the mass of both interacting objects, more massive objects will attract each other with a greater gravitational force. if the mass of one of the objects is doubled, then the force of gravity between them is doubled.

igneous rocks which formed by the crystallization of magma at the surface of the earth called extrusive rocks. they are characterized by fine-grained textures because the rapid cooling at or near the surface did not provide enough time for large crystals to grow.
