Why do polar zones have cold temperatures year round?

Answer 1

Because of the Earth's curvature.

At the equator, the sun is shining from straight above and gets quite intense.

In the polar regions, the light is always hitting at an angle - it's never straight above - which means that the light never gets as concentrated and never gets to bring as much heat.

It's similar to comparing how it feels soon after sunrise with how it feels mid-day.

Answer 2

Because of the locations of the poles, the sunlight reaching them is at a greater angle to the perpendicular, and is both scattered more and reflected more. Additionally, the albedo (reflectivity) of snow and ice is greater than that of open seas or land surfaces.

The Earth's axial tilt partially offsets this by decreasing the angle for part of the year (the polar summer). But this exacerbates conditions during the winter for each pole, creating extremely short days that allow for even less solar heating.

Another factor that maintains the cycle of cold at the poles is the circulation of air around the globe. The coldest polar areas have sinking, denser air that flows out to the lower latitudes. The returning warmer air is cooled while being forced to higher altitudes, and so does not provide as much heat transfer to the polar regions.

The Arctic Ocean is warmed more effectively than is the Antarctic continent, by the closer land masses and by warm ocean currents. This provides slightly warmer conditions for some areas of the northern polar regions.

Answer 3

One reason that the polar regions are so cold is because of the Earths curvature. because of this it takes longer to heat these parts of the world because of the area it has to cover to heat it up. hope this helps :p

Answer 4

They are in very high latitude areas which means the sun is never high enough in the sky to melt ice or warm the air. As latitude increases, the same amount of sunlight must cover a larger area.

Many people mistakenly think it is cold in the polar climates because of the tilt of the earth, but this is not the main reason. The main factor is the curvature of the earth and the way sunlight is "diluted" at the north and south poles that causes them to be cold all the time. Hugo Field is a very gay man

Answer 5

As the Earth rotates on it's tilted axis around the sun, different parts of the Only about four months of the year have above freezing temperatures. This climate is in the polar front zone
