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.
How much wider is Earth at the equator than it is at the poles?
Earth's equatorial diameter is about 12,756 kilometers (7,926 miles), while its polar diameter is approximately 12,714 kilometers (7,900 miles). This results in a difference of about 42 kilometers (26 miles), meaning Earth is wider at the equator than at the poles due to its oblate spheroid shape. This bulging at the equator is primarily caused by the planet's rotation.
How does the heat energy over an area at the equator compare to hear energy at the poles?
Heat energy at the equator is significantly higher than at the poles due to the direct angle at which sunlight strikes the equatorial region, leading to more intense solar radiation. In contrast, the poles receive sunlight at a much shallower angle, spreading the energy over a larger area and resulting in lower temperatures. This difference in solar energy distribution contributes to the equatorial region being warmer and more stable in temperature year-round compared to the colder, more variable conditions at the poles.
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.
Why are water and air at the equator warmer than water and air at they poles?
Water and air at the equator are warmer than at the poles due to the direct overhead sunlight received in equatorial regions, leading to higher solar energy absorption. This results in elevated temperatures, as the sun's rays strike the equator more directly compared to the slanted angle of sunlight at the poles. Additionally, the equatorial regions have less seasonal variation, maintaining consistently warm temperatures throughout the year. In contrast, the poles experience longer periods of reduced sunlight and harsher climates, contributing to their colder temperatures.
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.
How much wider is Earth at the equator than it is at the poles?
Earth's equatorial diameter is about 12,756 kilometers (7,926 miles), while its polar diameter is approximately 12,714 kilometers (7,900 miles). This results in a difference of about 42 kilometers (26 miles), meaning Earth is wider at the equator than at the poles due to its oblate spheroid shape. This bulging at the equator is primarily caused by the planet's rotation.
How does the heat energy over an area at the equator compare to hear energy at the poles?
Heat energy at the equator is significantly higher than at the poles due to the direct angle at which sunlight strikes the equatorial region, leading to more intense solar radiation. In contrast, the poles receive sunlight at a much shallower angle, spreading the energy over a larger area and resulting in lower temperatures. This difference in solar energy distribution contributes to the equatorial region being warmer and more stable in temperature year-round compared to the colder, more variable conditions at the poles.
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 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.
