Contour lines represent elevation changes. The closer contour lines are together, the steeper the slope. Blue lines represent water features such as rivers and lakes.
Look at a map. The ones that arent landlocked have blue squiggly lines near them.
Contour lines are used on a topographic map to show elevation. Each contour line represents a specific elevation above sea level, allowing users to visualize the topography of the land. The closer together the contour lines, the steeper the terrain.
mostly rivers, but it could also be streams
Typically, climate graphs use blue bars to represent precipitation, red bars to represent temperature, and black lines to represent average temperature.

Blue is often used to represent low elevation on topographic maps. This color is commonly associated with bodies of water or areas close to sea level.

mostly rivers, but it could also be streams
The topographic maps have colors that define features. Blue represents bodies of water, green the vegatation, red the main avenues, black the manmade objects such as builduings and brown wich represent the land contour lines. The valleys are mostly flat with most of the time a stream running trough it or near it. Anyways to illustrate the valleys the brown land contour lines are used.
Typically, climate graphs use blue bars to represent precipitation, red bars to represent temperature, and black lines to represent average temperature.
Contour lines of equal elevation on a topographic map are commonly coloured brown. On a marine chart, the lines of equal depth are often coloured blue. The isobar lines of equal pressure are mostly coloured black, but that may be a choice forced by available technology.
13, to represent the original 13 colonies
The stripes, which alternate red and blue, represent the 13 original colonies that founded the country.
