I’m studying for my Environmental Science class and need an explanation.

The questions on this individual assignment (see attached document above) require you to analyze materials covered in lectures 5, 6 and 7. The answers for these questions can be found in lectures, readings, handouts and/or by some searching on the Internet. Provide as much detail as appropriate. This is not a group project – these should be your own answers.
