A rising parcel of air that does not exchange heat with its surroundings and is solely a function of pressure changes is an example of a. frontal lifting b. convect?? c. forced lifting. d. adiabatic process 15. Blanket-like, layered clouds that cover large areas are called a. cumulonimbus couds b. cirrus clouds c. cumulus clouds d. stratus clouds 16. Which statement favors cloud formation? air temperature is cooled to reduce its moisture holding capacity warming of a parcel of air relative humidity is 0% condensation nuclei have been removed from the air a. b. c, d. 17. Thin, high wispy clouds composed almost entirely of ice crystals are called a. altostratus b. stratus c. cumulus d. cirrus 18 of the air layer at the ground level falls below the dew point develops at night when the temperature a. frozen fog b. advection fog c. radiation fog d. sea fog 19 moves over a cold surface forms when relatively warm, moist air a. advection fog b. steam fog c. radiation fog d. hailExplanation / Answer
13) b
air parcels expand when it move upwards in the troposphere and the temperature decreases.
14)d
in an adiabatic process there is no transfer of heat and matter between a thermodynamic system and its surrounding.
15)d
stratus clouds are low level clouds formed below 2000 meters, in a horizontally layered manner,
16)b
when the warm air formed they start to rise and as it ascend through the atmosphere its temperature falls down and hence form clouds.
17)d
its a high level cloud which form 5km to 14 km above sea level.they usually appears in white or light grey in color.
18)c
its a common fog during the fall and winter, and it form in the night when the air close to the ground cools.
19)a
its a common phenomenon where warm front passes over an area covered with snow pack,
