Gizmo Summary

Based on my observations the two factors that cause seasons are the tilt of Earth's axis and revolution. The revolution of the Earth causes seasons because as it revolves around the sun the axis points in different directions. So one hemisphere is getting more direct sunlight than the other therefore it is warmer or cooler in one hemisphere then seasons are caused. The seasons in the two hemispheres of the Earth are always opposite. The tilt of Earth's axis causes seasons because the tilt makes one hemisphere receive more direct sunlight. In conclusion the tilt of Earth's axis and revolution of Earth around the sun cause seasons.
