Why north pole and south pole was cold?

Because the Earth is tilted on an axis, the equator is always closest to the sun. The North and South poles are the parts of the Earth furthest away from the sun at all times WRONG! Because the earth is tilted on its axis the equator is closest to sun for only a moment twice a year!

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
