2) why is snow white when water is clear?
So, since snow is frozen water, and we all know that frozen water is clear, why does snow have a distinctive color? To understand this, we need to back up and look at an individual piece of ice. Ice is not transparent; it's actually translucent. This means that the light photons don't pass right through the material in a direct path -- the material's particles change the light's direction. This happens because the distances between some atoms in the ice's molecular structure are close to the height of light wavelengths, which means the light photons will interact with the structures. The result is that the light photon's path is altered and it exits the ice in a different direction than it entered the ice.
3) how much wood would a woodchuck chuck if a woodchuck could chuck wood?
This is difficult to question answer. The amount of wood that woodchucks would chuck on a given day varies greatly with the individual woodchuck. According to a Wall Street Journal article, New York State wildlife expert Richard Thomas found that a woodchuck could chuck around 35 cubic feet of dirt in the course of digging a burrow. Thomas reasoned that if a woodchuck could chuck wood, he would chuck an amount equal to 700 pounds.
