List two reasons for the change in seasons...
1. The tilt of the Earths rotational axis - The Hemisphere tilted toward the sun gets more daylight (longer days) and more total sunlight (warmer in summer).*The earths tilt cause radiation to strike the hemispheres at different angles
2. The Earths motion around the Sun. Since the Earths orbit is an ellipse, distance btwn S & E changes throughout the yr.
