...solar radiation passes through the atmosphere and warms up the more massive and dense land masses and oceans below. These absorb and retain heat energy which is then re-radiated at infrared wavelengths that do not pass so easily through the air as the incoming radiation. This is not a uniform process, however. The oceans have a temperature variation which is less (i.e....

...energy source in the future. On the way, you've also learned how to make and record observations in a systematic way, how to plot graphs, and how to interpret your data. Now, both of the experiments revealed some important facts about water. And this week, you're going to do another simple experiment that will reveal something astonishing. You're going to freeze some...
