When a (Blank 1) air mass moves toward a warmer air mass, it causes a cold front. The (Blank 2) air rises, leaving (Blank 3) tem
peratures in the region. On a weather map, a blue line with (Blank 4) represents the front. Blank 1: cold, warm
Blank 2: cold, warm
Blank 3: colder, warmer
Blank 4: semicircles, triangles
when a cold air mass moves toward a warmer air mass, it causes a cold front. the warm air rises, leaving colder temperatures in the region. on a weather map,a blue line with semicircles represents the front.
this process of movement of a cold air mass towards a warmer air mass is called a A cold weather front.
semicircles are used to represent weather fronts in a weather map.the only difference between the semicircle of a cold weather front and a hot weather front is the color associated with the semicircles. instead of triangles.
