My Oceanography teacher from time to time gives us information to look-up that he doesn't know for extra credit. So, I turn to you all to assist me in formulating some answers. 1) Why don't Violet wavelengths penetrate deeper than blue or green? If they did, then you could say that the shorter the wavelength, the longer the penetration of light. 2) Why do clouds have different shapes? I'd guess because it's all relative to how the water vapors condense at the Dew Point and take shape, but I'm not positive. 3) Finally, what's the difference between a calorie and Calorie? calorie is the amount of heat required to raise/lower the temperature of water. Calorie on the otherhand, I'm not sure of how to explain it. Something to do with food Those are the questions. Anyone?
