The planet Earth has a rather slight equatorial bulge; its equatorial diameter is about 43 km (27 mi) greater than its polar diameter, with a difference of about 1⁄298 of the equatorial diameter. If Earth were scaled down to a globe with an equatorial diameter of 1 metre (3.3 ft), that difference would be only 3 mm … See more An equatorial bulge is a difference between the equatorial and polar diameters of a planet, due to the centrifugal force exerted by the rotation about the body's axis. A rotating body tends to form an oblate spheroid rather … See more The fact that the Earth's gravitational field slightly deviates from being spherically symmetrical also affects the orbits of satellites through secular orbital precessions. They … See more • Astronomical object § Shape • Clairaut's theorem (gravity) • Earth's gravity • Planetary flattening See more Gravity tends to contract a celestial body into a sphere, the shape for which all the mass is as close to the center of gravity as possible. Rotation causes a distortion from this spherical shape; a common measure of the distortion is the flattening (sometimes called ellipticity or … See more Because of a planet's rotation around its own axis, the gravitational acceleration is less at the equator than at the poles. In the 17th century, following the invention of the pendulum clock, … See more WebThe Bulging Earth . According to Newtonian mechanics the spinning of a planet on its axis should cause it to bulge at the equator. This is the content of Proposition 18 of Book III of the Principia, and in Proposition 19 …

WebApr 21, 2024 · No, it isn’t. The earth is in fact like a rubber ball which has been gently squashed at the top and bottom, so that it is widest at the equator. It also has four bulges which form rough corners. These are in Ireland, and near the countries of Peru, South Africa and New Guinea. Scientists call the earth’s shape an ‘oblate spheroid’. Weba. Neap tides result from destructive interference between the solar and lunar tidal bulges. b. Spring tides result from constructive interference between the solar and lunar tidal bulges. c. Tides are greatest when the Moon is at perigee and Earth is at perihelion. d. Tides are greatest when the Moon is at apogee and Earth is at aphelion. e.
