Does the earth bulge at the poles

WebOct 12, 2024 · Clouds, ocean currents, and long-range missiles all would behave differently if Earth were perfectly spherical. This bulge exists because of a force created by Earth's rotation. As a result, a person on the equator is over 13 miles farther from Earth's center than a person on the North Pole is. WebMar 13, 2024 · In addition to bulging in the middle, Earth’s poles are slightly flattened. The geoid describes the model shape of Earth, and is used to calculate precise surface locations.

Axial precession - Wikipedia

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 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.

WebAug 6, 2024 · Earth does not always spin on an axis running through its poles. Instead, it wobbles irregularly over time, drifting toward North America throughout most of the 20th Century (green arrow). That direction has changed drastically due to changes in water mass on Earth. Credits: NASA/JPL-Caltech WebLots of places state that the Earth's gravity is stronger at the poles than the equator for two reasons: The centrifugal force cancels out the gravity minimally, more so at the equator than at the poles. The poles are closer to the center due to the equatorial bulge, and thus have a stronger gravitational field.

WebAs the Moon’s gravity tugs at Earth, it shifts Earth’s mass, distorting its shape ever so slightly into that of a football ― elongated at the equator and shortened at the poles. This effect on the solid Earth can be detected by scientific instruments, but we can watch the same changes to Earth’s oceans just by visiting the beach. ⚠️
