c.air masses with high or low temperatures
d.stationary air masses

Answer 1

6. Decreases by absorbing heat energy from the atmosphere.
7. I'm guessing more from the ocean. Reflectivity higher, but its a guess.
8. Atmospheric density decreases with altitude.
9. Sub-polar lows are not winds.
10a and 11b best guesses.
