Give an example of how the apparent motion of an object depends on the observer's motion.

So let's have 2 situations. Situation 1, you are in a car moving right at 20MPH, and you pass a car that isn't moving at all. And situation 2, you are in a car moving right at 20MPH and a car is coming towards you at 10MPH. In situation 1, the apparent motion of the second car is, say, 1, because only you are moving to close the distance between yourself and it. In situation 2, the apparent motion of the second car is .5, because the distance is decreasing faster since ture moving toward each other. Fun fact: Light is funky however. If you go half the speed of light, and light passes you and goes at 300,000mph, light will still look like it is going 300,000mph to you, despite you covering half the ground it does in any time frame.

Depending on how the continental plates move it can cause a continental scale shift.
