Name two ways that you can determine which way a river flows on a topographic map. contour lines point upstream rivers flow downhill
What are the steps to draw a topographic profile place a piece of paper between the points mark where every contour line touches the edge of the paper determine the elevation of each mark paper on the graph and mark the place the elevation of each contour line
Using the map and chart below, construct a topographic map profile.
Please match the contour map on the left with the profile on the right.
Depressions are shown by small marks (Hachur lines)pointing inward off the contour line
