Why equatorial distance is greater than polar distance of earth?
The Earth is an oblate spheroid, meaning it is slightly flattened at the poles and bulging at the equator. This bulging at the equator results in a greater equatorial distance compared to the polar distance. This is due to the centrifugal force generated by the Earth's rotation, which causes the equatorial regions to bulge outwards.
Is centrifugal force is more at equator than poles?
No, centrifugal force is greater at the poles than at the equator because the Earth's rotation causes a bulging effect at the equator that counteracts the centrifugal force. This is why objects weigh slightly less at the equator compared to the poles.
Is the earth slightly bulged at the poles?
Yes, the Earth is slightly bulged at the poles and flattened at the equator due to its rotation. This shape is known as an oblate spheroid. The polar diameter is shorter than the equatorial diameter by about 43 kilometers.
Why is distance around the equator measured at 24783mi when the distance around the earth is measured at 24901 mi?
The Earth is not a perfect sphere, but an oblate spheroid, which means it is slightly flattened at the poles and bulging at the equator. This difference in shape causes the equatorial circumference to be longer than the polar circumference. The measurements you provided reflect this difference in distance due to Earth's shape.
Why is gravity stronger at the poles than the equator?
Gravity is stronger at the poles than the equator because of the Earth's shape. The Earth is an oblate spheroid, meaning it is slightly flattened at the poles and bulges at the equator due to its rotation. This bulging at the equator causes objects to be farther away from the center of the Earth, resulting in weaker gravitational pull compared to the poles.
Effect of axial motion- bulging of the earth?
Axial motion, such as the Earth's rotation and precession, can cause bulging at the equator due to the centrifugal force generated by the spinning of the planet. This bulging is known as the equatorial bulge and results in the Earth being slightly flattened at the poles and slightly bulging at the equator.
Why equatorial distance is greater than polar distance of earth?
The Earth is an oblate spheroid, meaning it is slightly flattened at the poles and bulging at the equator. This bulging at the equator results in a greater equatorial distance compared to the polar distance. This is due to the centrifugal force generated by the Earth's rotation, which causes the equatorial regions to bulge outwards.
What is another adjective for equator?
Equatorial is the adjective related to the word equator. For instance: The equatorial climate is much warmer than that of the poles.
Does Jupiter have a larger equatorial diameter or polar diameter?
Jupiter spins so much faster than Earth, for instance, that its gassy state results in bulging out at the equator. The equatorial diameter is larger than the polar diameter.
Why is the equatorial region more stable than the axial region?
The equatorial region is more stable than the axial region because it receives more consistent sunlight and heat throughout the year, leading to a more balanced climate and fewer extreme temperature fluctuations.
Is centrifugal force is more at equator than poles?
No, centrifugal force is greater at the poles than at the equator because the Earth's rotation causes a bulging effect at the equator that counteracts the centrifugal force. This is why objects weigh slightly less at the equator compared to the poles.
Is the Earth's equatorial circumference the same as the polar circumference?
No. The polar circumference of the Earth is smaller than the equatorial circumference by about 41 miles or about 67 km. The Earth is a slightly "oblate spheroid" meaning it is slightly flattened (0.336%) at the poles, and bulging at the equator, due to its spin. The equatorial circumference of the Earth is about 40,075 kilometers (24,901 miles). The polar circumference of the Earth is about 40,008 kilometers (24,860 miles). See related questions and links for additional details.
Which part of the sun spins the fastest?
The equator of the sun spins faster than its poles. This is known as differential rotation, where the sun's rotation speed varies with latitude. At the equator, the sun completes a full rotation about once every 24 days, while at the poles it takes around 35 days.
Why Antarctica receives max radiation more than equatorial region in summer?
That's not true at all.
Why is surface salinity of an ocean higher in the subtropics than in the equatorial regions?
Surface salinity is higher in the subtropics than in the equatorial regions because of the combination of high evaporation rates and low precipitation levels in the subtropics. This leads to a concentration of salt in the surface waters as water evaporates, while the equatorial regions receive more rainfall that dilutes the salinity.
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.
The earth's polar diameter is shorter than the equatorial diameter by how many miles?
Oh honey, the Earth's polar diameter is about 7,900 miles, while the equatorial diameter is roughly 7,926 miles. So, grab a calculator and do the math, because that's a difference of about 26 miles. Just remember, size isn't everything, darling.
