It has an approximate value of 9. Weightlessness and zero gravity are two different things. At the pole, there is no centrifugal force because there is no distance from the center of rotation. It is the center of rotation. Nothing is subtracted, so it is greater. Second, bodies on the Earth experience more centrifugal force at the equator than elsewhere.

Mountain ranges, such as the Himalayas, have a high concentration of mass, and therefore have a strong gravity field. Ocean trenches, such as the Mariana Trench, have a low concentration of mass, and therefore have a weak gravity field.
Undersea mountains that line this section of the Mid-Atlantic Ridge contribute to the strong gravity field observed in this region. Recent Popular Related. Want to lose weight fast? No need to adjust your diet — just move to higher ground. Gravity is often assumed to be the same everywhere on Earth, but it varies because the planet is not perfectly spherical or uniformly dense.
Accurately constructing tunnels, dams and even tall buildings requires knowledge of the local gravity to guide GPS measurements of height, so higher resolution maps are important for civil engineering. The map consists of more than 3 billion points, with a resolution of about metres.
