This question is related to Weak Equivalence Principle. Is the earth actually expanding at a rate 9.8 ms-2, which is exactly countered by gravitational space expansion (g_rr term in Schwartzchild Metric)? Or it just acts as though it is expading, meaning it just expands space and slows down time (curves spacetime to be precise) so that the geodesic of a falling apple goes downwards?
