If Oil keeps getting dug from the Earth, what will keep our Core and our Gravity alive?

Answer 1

The empty space created by the extraction of oil is replaced by water. Comparing the extraction quantity of oil to the available source of sea water is much more higher.

Answer 2

Oil does not come from the core -- oil deposits are not that deep. Oil lies in the crust.

Burning oil does not change the mass of the Earth, since burning oil does not actually destroy it - matter cannot be created nor destroyed - it simply becomes smoke. The smoke from the burning oil is still in the Earth's atmosphere. Since the mass of the Earth is the same, then the gravity stays the same.

Answer 3

By "keep our Core... alive" I'm assuming you mean maintaining the heat at the center of the Earth. Removing oil from the crust doesn't change the heat of Earth's mantle/core. As far as gravity, Earth will always have its gravity no matter what we do (well, perhaps short of blowing up the whole planet).

Answer 4

a) Neither the core nor the gravity is "alive". -2 points.
b) The core is made of iron, which is not in useful oil. (we can't dig that deep anyway)
c) Oil doesn't contribute that much to our gravity, and the mass doesn't actually leave earth, so pumping out oil shouldn't reduce earth's gravitational attraction at all.
