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 is polar flattening and why is the polar flattening of Saturn unique?
Polar flattening refers to the phenomenon where a planet's shape is not a perfect sphere but is instead slightly compressed at the poles and bulging at the equator due to its rotation. Saturn exhibits significant polar flattening because it has a fast rotation rate and a low density, leading to a pronounced equatorial bulge. This flattening is unique among planets in the solar system, as Saturn's equatorial diameter is markedly larger than its polar diameter, making it one of the most oblate planets. The degree of this flattening contributes to Saturn's distinctive appearance and is a key factor in its atmospheric dynamics.
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 is the average day time for Saturn?
A day on Saturn, or its rotation period, is approximately 10.7 hours. This rapid rotation causes the planet to have a noticeable flattening at the poles and a bulging equator. Despite its massive size, Saturn's fast spin contributes to its unique atmospheric dynamics and weather patterns.
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.
