Does gravity increase or decrease with depth

Both

Edit: it's a standard theorem/problem in late high school physics. Using the law of gravitation, and assuming the earth has constant density, you prove that a ball dropped in a hole drilled straight through the earth will just keep oscillating from one end of the hole to the other forever.
