(PhysOrg.com) -- Although it may seem like gravity is the same everywhere on the Earth, it actually varies a small amount from place to place. Factors such as mountains, ocean trenches, and interior density variations can all cause gravity differences. By measuring the gravity field of Earth or another planet, scientists can gain insight into that planet's otherwise hidden geological features.
