What is topography?
Topography is the shape or configuration of the land, represented on a map by contour lines, hypsometric tints, and relief shading.
What does a topographic map tell you, that other maps can't?
.Topographic maps are used to show the terrain of the earth or land. They show mountains, valleys, and islands and the 'lay of the land' so to speak. They also show man-made parts of the terrain.
Who might use a topographic map ( and why)?
.pilot; firefighter.
Define the following:
Elevation: The hight of a place relative to a reference height.
Contour Lines: a line connecting point that have the same elevation.
Contour Interval: The difference in elevation between two adjacent contour lines.
Depression Contour: Contour lines indicating a downward slope ( drawn with hatch marks).

Practice Questions:
1) Which of the topographic maps shows two peaks? C
Which side has higher elevation? Left side
2) Which topographic map shows the steepest cliff? C
Where is it ? On the left between 500 & 600
3) Can you ell the elevation of the topographic feature in plot B exactly ? If so, what is the elevation, if not, why and what would be your closest guess?
- Not, because impossible to guess the height on the top we don't know actually the height, and the hieght not greater than 700
4) Which topographic map has a contour interval of 50 feet? A
5) Which of the topographic maps depicts a canyon, or depression? B
Which side has higher elevation? Left side
