What force is most responsible for Earth's orbit around the sun?
Gravitational Force
What is the difference between revolution and rotation? How long does each take?
Revolution is the movement of the Earth around the Sun and it takes 365 and 1/4 days. Rotation is something spinning on an axis and it takes Earth 24 hours.
What two factors are responsible for the creation of the seasons?
The tilt of the Earth's axis and the revolution of the Earth around the Sun.
