The Key, or Legend, or a map gives a list of the symbols used on the map and what they represent. There is a fairly standard set of symbols used for different types of map so that anyone looking at the map can understand what it is being shown. For example, on a weather map a cold front is shown as a black line with semi-circular bumps (in blue if coloured), a warm front is shown as a black line with triangles (in red if coloured) and an occluded front is shown as a black line with alternate semi-circular bumps and triangles.

That depends on what type of map you are referring to. On a weather map it's usually part of a warm front. On a road map they could be any type of road the cartographer specifies. On a topographical map they could be elevation lines. On the Washington Transit Map it's the red line train. Check the legend and it will more than likely tell you.
A warm front on a weather map is always a red line with red half circles on it.
