Written Response
21. At a warm front, cirrus clouds form as a warm
air mass gently rises over a cold air mass and cools.
At a cold front, a cold air mass pushes underneath a
warm air mass. Differences in pressure cause gusty
winds and rain.
22. Evaporation of perspiration on the skin cools the
body. High humidity slows the rate of evaporation,
so perspiration does not evaporate and cool the skin
as effectively when the humidity is high.
