Cause the equator goes round the differ ways to the hemisphere so the north hemisphere goes right and the south hemisphere goes left then the equator is the thing which moves it! The earth leans from one angle to the next. The north axes is always facing the northern star and as the earth rotates the sun, that's when the angle comes in.
Ones part of the earth is closer than the other. Thus, opposite seasons. Both of the angles stop at ether the tropic lines (Cancer and Capricorn).
When it's fall and spring, there is no angle. At that time, the line that it "stops" at is the equator Hope that helps.
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.
