Topographic map
A two-dimensional model of the earths surface
Contour lines
Connects points of equal elevation
Contour interval
The difference in elevation between each line. The difference must be the same between ALL lines
Index contour
Usually every 5th line is printed darker and has an elevation printed on it
Weathering
Processes that work to break down rock.
Bench mark
A location whose exact elevation is known and is noted on a brass or aluminum plate. Benchmarks are shown on maps by an x with the letters BM written next to them
Map scale
Indicates the distance on the map compared to distance in the real world
