Yes. There's gravity everywhere - it's an intrinsic property of all matter that has non-zero mass. If you were at the centre of the Earth it would feel like you were weightless. This is because all of the forces on you that result from the Earth's gravity are balanced. Mass attracts mass. There is the same amount of earthly mass in every direction. So you would be pulled equally in each direction and the net force on your body would be zero. This does not mean that there is no gravity at the Earth's centre. There's an awful lot of gravity there!

because it has no surface area

revengerdon: Then what is the relation between surface area and gravity

revengerdon: Correct answer is : Acceleration due to the earth's gravity is zero at the centre of the Earth because at that point the mass of the earth is equally distributed in all directions, so pulling equally in all directions for a net zero pull.

As the distance from the centre decreases, the acceleration due to gravity also decreases.
At the centre the distance is zero, hence gravity is zero.
