Gizmo Seasons

The main factor that causes seasons is Earth's tilt. When the Earth is tilted away from the sun, the Southern Hemisphere receives the most direct sunlight, and is in summer. When the Earth is tilted towards the sun, the Northern Hemisphere receives the most sunlight, and is in summer. Another factor that causes seasons is earth's revolution. When the earth revolves, the hemispheres are facing the sun in different ways. For example, when its summer in Colorado, the Northern Hemishere is recieving the most direct sunlight, because at that point, the north is tilted toward the sun.
