Hi,

They form over water with cool, moist air

Explanation:

Maritime polar air masses originate are formed over cold ocean currents.This air mass has less moisture content compared to maritime tropical air masses which are warm and moist.Maritime polar air masses can bring rain and snow to cover a very large area. This air mass can produce fog and a cloudy weather.The Pacific North west experiences this air mass regularly.

d is the logical answer but im not a 100% sure

for e2020. the answer would be some directions from the mountain range so we can find mt. whitney. to locate which direction is north, you should use a   compass. this would not only find mt. whitney, but also becuase of this long paragraph you would get points because it's not like anyone actually reads your work becuase once they read the first sentence it sounds dumb enough to not read becuase i'm not good at answering this but the answer is compass for your benefit.

for e2020 ; -;
