Question

Please tell me where is the base of earth gravity ?

Answer 1

The CAUSE of earth's gravity is the earth's MASS.

Gravitational attraction is a natural property of gravitational mass.

Generally the center of mass of a spheroid like the earth is the exact center of the sphere and is where the gravitational attraction is postulated to originate from, but it is all the tiny bits and pieces of matter that add up to create it.

In truth, as we understand it today, the basis of gravitation is the warpage of space-time caused by a gravitational mass, like the earth.

Answer 2

The base of earth gravity is in the center of the earth. It is same with the other planets and astronomic objects.

Answer 3

If you mean where is the originating location of the gravity of the Earth, the answer is the center of the inner core or the center of the Earth.
