Why do seasons change?
On the earth, the availability of sunlight is different. The changes in the sunlight availability in a particular region on land affect the temperature of that region; this is why the season changes. The earths tilt and revolution affects how much sunlight a hemisphere will receive.

What does the strength of gravity's pull depend on?
The distance between the objects. The further away an object is, the weaker the gravity between the object is.
