    1: increases increases#2: cloud types#3: heat up, vapor#4: kill birds#5: water moves#6: I wasn’t there.#7: fell slightly#8: T decreases#9: I wasn’t there.#10: poleward of 60 degrees N or S.Cold air sinks at the poles, and the high pressure forces it equatorward;the Coriolis acceleration sends it westward,because its eastward momentum is insufficient to”keep up” with the wider latitude circles it is approaching.
