Answer:sunlight strikes the poles at an oblique angle.
From the polar regions, the sun is low in the sky, so that the sunlight hits the earth at a low angle, as it does for us in the morning and evening. This low angle means that the sunlight is more spread out, and thus warms the surface less.
The polar regions of earth are not cooler because they are farther away from the equator, and they are not cooler because they are farther from the sun. The poles are only about 3000 km farther from the sun than is the equator at noon. This is about 0.002% of the earth-sun distance -- hardly significant.
What else can I help you with?
How do the total number of hours of sun light in a year compare for a tropical regions and polar regions of the earth Why are polar regions so much cooler?
Tropical regions receive more sunlight hours throughout the year, as they are closer to the equator and experience more direct sunlight. In contrast, polar regions receive less sunlight due to their high latitude and tilt of the Earth's axis, resulting in cooler temperatures. The angle at which sunlight strikes the Earth's surface in polar regions is also much lower, leading to less heat absorption.
Does a tropical air mass tend to be warmer than polar air masses?
Yes, tropical air masses tend to be warmer than polar air masses because they originate in regions closer to the equator where temperatures are higher. Polar air masses, on the other hand, come from regions closer to the poles where temperatures are colder.
Describe the temperature of the currents that flow away from the equator and explain why they are this way?
Heating by the sun near the equator makes the water there warm. In the polar regions, the water is cold. Cold water weighs more than warm and as a result, the warm waters of the equator drift toward the poles. The cold wear from the poles then flows toward the equator to replace the warm water that is leaving.
Why is weathering faster than in polar regions?
Weathering is faster in non-polar regions than in polar regions because of the presence of liquid water in the form of rain, which can speed up chemical weathering processes. In polar regions, where temperatures are generally colder, water is typically frozen and therefore not as readily available to participate in weathering processes. Additionally, the freeze-thaw cycle in non-polar regions can also contribute to mechanical weathering, further accelerating the breakdown of rocks.
Does it rain in the polar regions?
Yes, it can rain in the polar regions during the summer months when temperatures rise above freezing. However, in general, the polar regions are more likely to experience snowfall rather than rain due to the cold temperatures.
What region usually has temperatures cooler than temperatures near the equator?
Regions closer to the poles, such as the Arctic or Antarctic regions, typically have cooler temperatures compared to regions near the equator. This is due to the angle at which sunlight reaches the Earth at different latitudes, resulting in less direct sunlight and cooler temperatures in polar regions.
Why are polar regions cooler than equatorial regions?
The polar regions get the least amount of warming rays from the Sun.
What regions usually has temperatures cooler than temperatures near the equator?
Temperate Zones are usually cooler than the temperatures near the equator.
What contributes to warmer temperatures as you travel from the polar regions toward the equator?
The equator faces the sun more directly than the polar regions do, and therefore gets more sunlight and more resulting heat.
If the arctic is under the equator like Australia how is it so cold?
The arctic is NOT "under the equator." It is at the north polar region. The Antarctic is at the south polar region; the average temp in the polar regions are much colder than at the equator.
Is the water hot in the equator?
It is warmer than in temperate and polar regions. It is not hot, though.
Polar air masses are cooler than tropical air masses because the place where they start I what?
Polar air masses are cooler than tropical air masses because they originate from high-latitude regions closer to the poles, where temperatures are generally colder. Conversely, tropical air masses originate from low-latitude regions near the equator, where temperatures are generally warmer. This temperature difference between the two regions accounts for the inherent temperature contrast between polar and tropical air masses.
How much more direct sunlight does the polar region receive than the equator?
The polar regions never receive any direct sunlight.
How do the total number of hours of sun light in a year compare for a tropical regions and polar regions of the earth Why are polar regions so much cooler?
Tropical regions receive more sunlight hours throughout the year, as they are closer to the equator and experience more direct sunlight. In contrast, polar regions receive less sunlight due to their high latitude and tilt of the Earth's axis, resulting in cooler temperatures. The angle at which sunlight strikes the Earth's surface in polar regions is also much lower, leading to less heat absorption.
Why are earth's polar regions never very warm?
Earth's polar regions are the areas of the globe surrounding the poles also known..part of what little sunlight the Polar regions receive, contributing to the cold.
Why do air masses tend to travel from polar regions toward the equator?
Air masses tend to travel from polar regions toward the equator due to the Earth's rotation and differences in temperature and pressure. The uneven heating of the Earth's surface causes warmer air to rise at the equator, creating low pressure, while cooler air in polar regions leads to high pressure. This pressure difference drives the movement of air masses in a process known as atmospheric circulation. Additionally, the Coriolis effect influences their paths, causing them to curve rather than move in a straight line.
Is the thickness of earth atmosphere the same in polar regions as equatorial regions?
Yes, the thickness varies from te equatoral to the polar regions due to the Earth's rotation. The atmosphere is thicker at the equator than the poles. this is due to the earths rotation and centripital force.
