The S side of Earth for example is face to the sun which is summer
The N side of Earth of pointed away which is winter.

Explanation:
Law of conservation of momentum states that in an isolated system when two objects collide with each other then total momentum before and after the collision is equal.
Thus, we can conclude that the law of conservation of momentum states that the total momentum of interacting objects does not change. This means the total momentum before a collision or explosion is equal to the to momentum after a collision or explosion.
Electromagnetic Waves: This type of wave requires no medium (substance) to travel through.
