Answer:
Blank 1 : cold
Blank 2: warm
Blank 3: colder
Blank 4: semicircles
Explanation:
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.
