The difference between the seasons are one of the hemisphere's is preparing for the winter and the other hemisphere is preparing for summer.

3.The difference between Indirect light and direct light is that direct light has strong powerful and concentrated rays while Indirect light has weak and spread out rays.
4. The motion that causes the seasons is the Earth's Revolution around the sun.
5. The tilt affects the seasons by causing indirect light and direct light. If the Earth was not tilted both hemispheres would receive equal light and there would be no seasons.
