Answer to Question 1

Divergence aloft represents the outflow of air molecules that have been carried up from the surface by the rising air associated with low pressure. When the outflow of molecules at the top is greater than the inflow of molecules at the surface, more molecules will be exiting the low pressure system than are entering. This results in a deepening of the low pressure.

Answer to Question 2

carbon dioxide, methane, CFCs, water vapor, nitrous oxide
