Why is the troposphere thinner at the poles?
As air gets colder it contracts. While the total amount of air is about the same in any column of the troposphere, at the cold poles that column takes up less space, resulting in a shorter distance to the top of the troposphere.
Air near the equator average higher temperatures than air near the poles?
Yes, air near the equator is typically warmer than air near the poles due to the angle at which sunlight strikes the earth. Near the equator, sunlight is more concentrated, resulting in higher temperatures. In contrast, near the poles, sunlight is spread out over a larger area, leading to cooler temperatures.
Why is the circumference around the equator larger than that around the poles?
The Earth is not a perfect sphere but an oblate spheroid, meaning it is slightly flattened at the poles and bulging at the equator due to its rotation. This oblate shape causes the circumference around the equator to be larger than around the poles.
Caused by the uneven heating of earth and its atmosphere?
Pole. (The north and south poles. They get less heat than the equator because the sun's rays hit the equator more directly where they hit the poles at an angle and have to be spread over a larger area.)
Why are water and air at the equator warmer than water and air at the poles?
The equator receives more direct sunlight throughout the year, leading to higher temperatures. This causes the air and water at the equator to absorb and retain more heat compared to the poles, which receive sunlight at a lower angle and for shorter durations, resulting in cooler temperatures.
Which one is hotter the Equator or the Poles?
On our Earth, the Equator is comparatively warmer than either of 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 do poles receive less solar energy then the equator does?
The poles receive less solar energy then the equator does because the radiation from the sun has to pass through much more atmosphere to reach the poles than to reach the equator. During that transit, more of the energy is scattered on the path to the poles, and less reaches the ground there.
Why are averages temperatures higher at the equator than near the poles?
The energy that reaches the equator is more intense than the energy that strikes poles
Is the altitude of the tropopause greater at the equator than at the poles or at the poles than at the equator?
It is greater at the Equator. The boundary between the troposphere and the stratosphere varying in altitude from approximately 8 kilometers (5 miles) at the poles to approximately 18 kilometers (11 miles) at the equator.
Is the circumference of the earth measured around the surface or the atmosphere?
It is measured around the surface of the earth. The atmosphere has its own measurement excluded from that of the Earth. The Equator is bulged, and the Poles slightly flattened. The figure given is for sea level, and ignores any mountains. The Poles are about 21.4 km closer to the centre of the Earth than the Equator is.
Why are the regions away from the equator cool?
At the equator, the sun's rays strike the earth vertically - making their path through the atmosphere shorter than at the poles - thus more of the sun's energy reaches the earth's surface. Towards the poles, the angel of the sun's rays is flatter - meaning they pass through more of the earth's atmosphere.
Why is the troposphere thinner at the poles?
As air gets colder it contracts. While the total amount of air is about the same in any column of the troposphere, at the cold poles that column takes up less space, resulting in a shorter distance to the top of the troposphere.
Are the Poles of Uranus are hotter than its equator?
Yess
Why do the poles equator heat differently?
The poles receive less direct sunlight because of the tilt of the Earth's axis, leading to colder temperatures. At the equator, the sun's rays strike more directly, generating warmer temperatures. This temperature difference creates atmospheric circulation patterns that further contribute to the variation in heat between the poles and the equator.
Is the martian atmosphere much thinner than earth's atmosphere?
yes
Why is ocean water near the equator warmer than ocean water at the poles?
The ocean receives most of its heat along the equator, where incoming solar radiation is about double that received at the poles. Hence, sea surfaces are much warmer along the equator than at the poles.
