What causes polar flattening of the Earth?
The spinning motion of the Earth causes it to flatten slightly at the poles and bulge at the equator. This flattening, known as oblateness, is a result of the centrifugal force counteracting the gravitational force at the equator. The shape of the Earth is an oblate spheroid due to this flattening.
Which planet has the greatest polar flattening?
Saturn has the greatest polar flattening of any planet in our solar system. Its oblateness, or polar flattening, is due to its rapid rotation, causing it to bulge at the equator and flatten at the poles.
What causes slight flattening of the earth at two poles?
used by spinning motion of the earth around its axis passing through the poles...the force being max at the equator...since at tym of formation, earth was in fluid state, the force of cohesion was small & could not balance the centrifugal force...hence it bulged out at the equator
What does Jupiter's degree of flattening tell us about its interior?
Jupiter's degree of flattening indicates that it is not a perfect sphere, suggesting that the planet rotates rapidly. This spin causes the equator to bulge out and the poles to flatten, giving a clue about its internal structure and composition.
What causes earth flattening of the earth at two poles?

What is polar flattening?
Polar flattening, also known as oblateness, refers to the deviation of a planet's shape from a perfect sphere, resulting in a slightly flattened appearance at the poles compared to the equator. This occurs due to centrifugal forces caused by the planet's rotation. For example, Earth is an oblate spheroid with a polar flattening of about 0.00335.
In what two ways does Jupiter's rapid rotation affect the planet?
Jupiter's rapid rotation causes its oblate shape, flattening the poles and bulging at the equator. This rotation also generates a powerful magnetic field, which interacts with its moons and contributes to intense auroras.
What causes the flattening of the philtrum?
The flattening of the philtrum can be caused by genetics, developmental disorders, or conditions like fetal alcohol syndrome. The philtrum is formed during fetal development and its shape can be influenced by a variety of factors.
What is rotational flattening?
Rotational flattening refers to the phenomenon where a celestial body, such as a planet or moon, becomes slightly flattened at the poles and bulges at the equator due to its rotation. This effect occurs because the centrifugal force generated by the body's rotation counteracts gravitational forces, causing it to assume an oblate spheroid shape rather than a perfect sphere. The degree of flattening is influenced by the body's rotation speed, density, and structural composition. For example, Earth is not a perfect sphere but is slightly flattened at the poles and bulging at the equator due to this effect.
What does the earth bulge slightly around?
The earth rotates at approximately 15 degrees per hour (24hrs x 15 degrees=360 deg). centrifugal force from this rotation causes the panet to bulge at the equator and consequently causes some flattening at the poles. given the earth rotates so slowly, this is not apparent in visual images taken by sattelite or space vehicle.
Why does saturn bulge out at the equator and flatten at the poles?
Saturn's day is about 10 and one half hours. This rapid rotation makes the largest polar flattening among the planets.
What is one way that Jupiters rapid rotation affects the planet?
Jupiter's rapid rotation causes its flattening at the poles and bulging at the equator, giving it an oblate spheroid shape. This fast rotation also generates a strong magnetic field, which interacts with the solar wind to create powerful auroras near its poles.
