Question

11) Which of the following describes Pressure Gradient Force? a. b. c. d. it causes deflection of winds from a straight path it decreases with height above the surface it drives air flow from areas of low pressure to areas of high pressure it drives air from areas of high pressure to areas of low pressure 12) The elevation at which the bottoms of clouds begin to form represents the elevation at which: a. b. C. d. Dew point occurs Relative humidity reaches 100% Relative humidity reaches 0% Both A and B 13) Which of the following is NOT correctly matched? a. b. c. d. High altitude clouds - stratus Thunderstorm clouds-cumulonimbus Thin, wispy clouds- cirrus Puffy clouds-cumulus 14) Where on Lake Erie is a lake-effect snowfall LEAST likely to occur? a. The far eastern shore (Buffalo) b. The southeastern shore (Cleveland) C. The far western shore (Toledo) d. Lake effect snow doesn't occur on the shores of Lake Erie 15) A mT air mass is likely to be than a cP air mass because the mT air mass a. b. c. d. Wetter; forms over the ocean Drier; forms over the ocean Wetter; forms over land Drier; is a cold air mass

Explanation / Answer

Ans 11) option D: it drives air from area of high pressure to area of low pressure.

Pressure gradient is force per unit area across a surface.Pressure gradient force is the force which result when there is difference in pressure across a surface. It travels from zone of high pressure to zone of low pressure.
