With all his gear, Neil Armstrong weighed 360 pounds on Earth. When he landed on the Moon, he weighed 60 pounds. Why? A. His mass changed while traveling to the Moon. B. The gravity on the Moon is six times the gravity on Earth. C. The gravity on the Moon is less than the gravity on Earth. D. He experienced the effects of a gravity slingshot.

C)  The gravity on the Moon is less than the gravity on Earth.

Explanation:

Since Moon is smaller than Earth, any mass on Moon will experience less gravitational force and so that mass will weigh less on Moon.

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.
