Why are the North and South poles much colder than the equator?

Answer 1

Essentially the ffirst answer...

The radiation that hits the poles is spread out over a larger area and is not as intense, thuse its not as hot. The equator gets more direct/intense sunlight. The poles also go from closest part of the earth to the sun to the furtherst part of the earth from the sun.

Answer 2

The equator is the closest point in the Earth to the sun, therefore it is hotter... Thinking like that, the north and south poles are the furthest points from the sun, and given seasons, sometimes they do not really see sun for a month or so, depending on the tilt and rotation of the Earth..

The North and South Poles are furthest from the sun, so they are the coldest. The further from the equator you travel, the cooler things are....


addendum:

Now what kind of person says bad answer to a science answer? Did you not go to school? I have the correct answer to this question.

To quote a source: the radiation that gets ‘out’ of the Earth’s atmosphere is not that different at pole and equator, because it just goes straight up. Therefore, as seen in the following figure, there is a net radiation surplus at the equator, and a radiation deficit at higher latitudes. Bottom line: It is hotter at the equator than at the poles because the Earth is round.

Answer 3

No, it's not because the equator is "closer" to the sun, that distance is really insignificant when you consider how far we really are from the sun. The reason the poles are colder (and also why there is a difference of temp from summer to winter) is because of how directly or indirectly solar radiation hits the area. More direct radiation goes through much less atmosphere and has much less time to be reflected also, while the very indirect radiation at the poles will travel through a much greater portion of the atmosphere and hit the groung at a much more acute angle

Answer 4

its using perspective at which the sunlight's rays hit Earth. The Earth rotates on an axis defined by the North and South poles, meaning the suns' rays are recieved with extra advantageous intensity on the equator. This has no longer something to do with distance. It has to do with the perspective the rays hit, the quantity of environment the rays could desire to return and forth by using, and so on. a extra useful question is could be why that's chillier at a given selection interior the wintry climate than the summer season. extra advantageous than 0.5 the faculty graduates asked this question in a contemporary polldidn't be responsive to. hint - it is not because of the fact the Earth is further from the sunlight in the process the wintry climate. easily anybody right here wanna take a crack at that one?

Answer 5

The stronger the magnetic field the more of the suns radiation it deflects. The equator is significantly closer to the sun than the poles and the solar radiation is more spread out at the poles therefore it is cooler than the equator.

Answer 6

Since we have a magnetic field we are able to have an atmosphere. Since we have an atmosphere we are able to regulate our temperature better than planets without one...IE (Mars). This allows the places on earth with limited visibility to the sun to remain cold due to the lack of energy received and sustained. The areas with the greatest visibility to the sun along the equator remain warmer due to time and direction / angle of exposure!

Answer 7

Heating due to solar radiation is less there because the angle of sunlight is always much more oblique than at the equator.

Answer 8

the sun rays being obscured by more atmospheric dust and particles, as the rays have to travel through longer distances of atmosphere, may contribute too even less solar radiation.

Answer 9

Lack of solar heating

Answer 10

The Sun's rays do not reach there.
