Red. Classifies cultural features, such as populated areas, main roads, and boundaries, on older maps. Brown. Identifies all relief features and elevation, such as contours on older edition maps, and cultivated land on red-light readable maps. Green.
What is the colour of hills?
Explanation: If you mean colours on maps to represent the height of hills and mountains, you could use the shades of any colour as a representation. Dark green usually represents low lying land, with lighter shades of green for higher elevations. Physical maps often use a palette of light to dark brown.
How many colors are on a map?

What are the four main uses of topographic maps?
Uses – Topographic maps have multiple uses in the present day: any type of geographic planning or large-scale architecture; earth sciences and many other geographic disciplines; mining and other earth-based endeavours (such as planning and constructing ponds); and recreational uses such as hiking or, in particular, ...
What are the 3 types of contour lines?
There are 3 kinds of contour lines you'll see on a map: intermediate, index, and supplementary. Index lines are the thickest contour lines and are usually labeled with a number at one point along the line. This tells you the elevation above sea level.
What is the purpose of the color on topo maps?

What color are contour lines?
On USGS maps, contour lines are colored brown and connect points of equal elevation, which means that if you trace a single contour line across a map you will be following the same elevation for the duration of the line. Contour lines on maps are evenly spaced by intervals that vary from map to map.
Why are contour lines important?
Contour Lines. Contour lines are perhaps the most important feature on any topo map because they, more than any other symbol, give us “the lay of the land.”. They do so by showing us the elevation and shape of the terrain.
Why is it important to understand symbols on a map?
Understanding the symbols on a map will greatly aid you in identifying features in real life and performing other tasks such as triangulating your position.
How many pages are there in the USGS topographic map?
The United States Geological Survey’s (USGS) guide to Topographic Map Symbols runs a total of four pages long and includes dozens of hiking symbols. While it would be perhaps superfluous to go through all of these symbols on this page, this list can be found in PDF format here.

Political maps will use more colors such as blue for water, red or black for cities,railways and road. While physical maps use color to show changes in elevation.
