MEANDER
bend In a river
OXBOW LAKE

topographic map
two dimensional model of earths surface
contour line
connects points of equal elevation
relief
difference between high and low elevations
contour interval
difference between each line
index Contour
usually every fifth one is printed darker and has elevation printed on it
rules for contours
contour lines never cross
contours from close loops even if not shown on the map
contours bend upstream when crossing a Stream
steeper slope
contour lines are closer together
Gradual slops
Contor lines are farther apart
benchmark
shown on maps by and asked with the letters BM written next to them
map scale
indicates the distance on the map and compared distance in the real world
