The amount of heat needed to increase the temperature of a 1-kilogram substance by 1°c is known as the

Specific heat.

"Different substances gain heat energy at different rates. A 1-kilogram substance's specific heat is a measure of how much heat must be added to it in order for its temperature to increase by 1°C."

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.
