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
The slight flattening of the Earth at the poles is due to the centrifugal force caused by the Earth's rotation. As the Earth spins on its axis, the centrifugal force causes the equator to bulge out slightly and the poles to flatten. This shape is known as an oblate spheroid.

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.
How the gravitational acceleration will change when you move from equator to north or south pole on the surface of earth?
The gravitational acceleration will decrease slightly as you move from the equator to the poles due to the Earth's shape (oblate spheroid). This is because the centrifugal force is greater at the equator compared to the poles, which causes a slight decrease in the net gravitational force experienced at the equator.
What causes the global convention current between the equation and the poles?
Temperature differences Earth's tilt
What causes the poles to be slightly off the true North and South poles?
The Earth's magnetic poles do not align perfectly with the geographic North and South poles due to the planet's molten iron core generating a magnetic field that is not perfectly symmetrical. This causes the magnetic poles to shift and be slightly off from the true geographic poles.
Why is there warm water near Earth's poles?
Warm water near Earth's poles can be attributed to ocean currents that transport heat from the equator towards the poles. Additionally, the Earth's tilt on its axis causes sunlight to hit the poles at a more direct angle during certain times of the year, leading to warming of surface waters.
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.
What causes the flattening of poles?
The rotation of the planet.

The earth is slightly bulged at the poles?
This slight bulging is due to the Earth's rotation. The centrifugal force generated as the Earth spins causes the equator to bulge out slightly, making it wider than the poles. This shape is known as an oblate spheroid.
Why the Earth is shaped as it is?
The earth is not perfectly round, but very slightly flattened at the poles, and with a very slight bulge at the equator - the shape is called "oblate". It is caused by the earths rotation on it's axis. Jupiter, which rotates much faster than the earth has even more pronounced bulging at the equator and flattening at the poles. It is not really obvious to the eye, but can easily be measured with scientific instruments.
Why is the earth circle?
The Earth is not a perfect circle; it is an oblate spheroid due to its rotation causing a slight flattening at the poles and bulging at the equator. This shape helps to balance the forces of gravity and rotation, creating a more stable planet.
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 the earth is pear shaped?
The shape of the Earth is not exactly pear-shaped, but slightly flattened at the poles and bulging at the equator due to its rotation. This is known as an oblate spheroid. The centrifugal force generated by the rotation of the Earth causes this slight distortion in its shape.
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.
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.
How the gravitational acceleration will change when you move from equator to north or south pole on the surface of earth?
The gravitational acceleration will decrease slightly as you move from the equator to the poles due to the Earth's shape (oblate spheroid). This is because the centrifugal force is greater at the equator compared to the poles, which causes a slight decrease in the net gravitational force experienced 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.
