Earth seasons are caused because of earths tilt on its axis and it position to the sun. When the earth is at a certain point in its orbit its tilted a certain way. That certain tilt makes it so more or less direct sunlight hits the earth. When more direct sunlight hits the earths northern hemisphere it is summer in the northern hemisphere. When more direct sunlight hits the southern hemisphere the southern hemisphere gets summer. That is the reason for earths seasons!
