Why would there be no seasons if the earth wasn't tilted on its axis?

A season is the result of how direct sunlight is received over a part of the earth. Because of the earth's axial tilt (it does not spin perpendicularly to its orbit around the sun), the hemisphere receiving the most direct sunlight alternates between the northern and southern hemispheres If the earth had zero axial tilt, the directness of sunlight would not vary throughout the year aside from orbital perihelion/aphelion (which has a much smaller effect than the axial tilt).

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.
