As a rocket moves farther and farther upward from the launch pad, what happens to the strength of earth's gravitational field around the rocket?
a. it gets weaker.
b. it grows stronger.
c. it remains constant.

force tends to be low and long diustance masses are high

as we know our atmosphere or air have different levels. every level has other gasses, and every gas has another permeability. when the light comes from lower permeability to higher permeability, it changes its direction. so that means that when the light comes from the moon to the earth, it changes it's direction many more times. it basically means that the shape of the light part of the moon is changed on the earth.
