Explain how Earth's revolution affects the amount of sunlight and darkness at the North and South Poles?

Answer 1

it's not the revolution, it's the tilt. the axis is tilted in such a way that the south pole sees the sun better in winter and the north pole in summer.

Answer 2

The earth revolution affects north and south pole the same way it affects the equator, only the effect of sunlight on these areas varies. On the equitorial areas the effect is more intense and direct while on the north and south pole has a glancing effect.

What really affecting the amount of sunlight and darkness on north and south is the degree of "tilt" the earth make every year. The earth make a 21 degree tilt from its original axis once a year. On winter the north pole axis tilt away from the sun that will shortened the amount of daylight and lengthened the amount of darkness while in the south pole its axis tilt closer to the sun that will lengthened the sunlight and shortened the darkness. On summertime its the reverse. Which mean too that when winter in the north it's summer in the south. Without this 21 degrees tilt we don't experienced four seasons.

I hope I satified your question.

Answer 3

Eath's revolution does not affect the AMOUNT of sunlight and darkness at the poles, but it affects the amount of TIME which you can see sun light.
The AMOUNT of sunlight at the poles is determined by its distance from the sun and the curved surface of the earth. The further it is from the sun, the less sunlight will be able to reach as the light energy becomes lesser as it travels the extra distance. The curved surface of the earth also disperse the amount of sunlight, as opposed to the concentrated sunlight at the equator. try drawing a globe and a thick ray of light shining at the pole, and there will be a difference in the length of the 2 lines repersenting the ray, and that shows that sunlight id dispersed. try this again with the ray at the euator, and youll find that the 2 lines are more or less equal.
As for the amount of TIME you see sunlight, i would have to agree with egan...

Answer 4

Has to do with the angle of the sun with respect to the poles during the different seasons. The equator has more direct sunlight, hence no extended periods of dark or light during the different seasons. Read the following, and go down to "day and night"...

Answer 5

the north and south poles arnt @ the top and bottom is kinda tilted so..

*well ya*

Answer 6

it does not affect it, if u r talking about the melting ice caps it is just the green house gases letting more of the suns rays down to the earth
