The more acute the angle at which the sunlight strikes, the more atmosphere that sunlight must pass through. Passing through more atmosphere will weaken and dim the light beams As the angle at which sunlight hits the earth changes, the same amount of sunlight is spread over different areas, so that near the poles each area of surface receives less intense radiation than an equivalent area near the poles.
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.
