U2L2 Topographic Maps

A map that shows natural and human-made features and the shape of Earth’s surface by using lines to represent different elevations

This type of map is the best tool for determining the shape and size of a landform (like a hill, valley, or erosional feature) if you cannot visit the location

This term refers to the difference between the highest and lowest elevations on a map

A line on a topographic map that connects all points of equal elevation

The difference in elevation between adjacent contour lines. This value is constant across the entire map.

• Take two adjacent index contour lines • Subtract the smaller from the greater. • Count how many contour lines are between • Divide the distance between the two index contour lines by the amount of contour lines between.

Through a circle/circles at the top.

By adding little marks onto the line. These are known as hatch marks.

Through broadly spaced contour lines.

Through close contour lines.

A river flows from higher points to lower points—track where elevation lowers.

When crossing a river, contour lines naturally form a V-shape that points upstream. Therefore, the river flows the opposite direction.
