A tank of water is separated into two sections. Hot green water is placed on one side of the tank and clear cold water is placed on the other side. What would you predict will happen when the partition separating the tank is removed? Why?

A) The water will cool without mixing as heat is transferred by conduction.
B) You will see the green colored water move and mix with the cold water due to radiation.
C) The clear water will move into the green water making it a lighter green by convection.
D) You will see the green colored water move and mix with the cold water due to convection.

B) You will see the green colored water move and mix with the cold water due to radiation.

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.
