1. Topography

2. Definition Study of Earth’s surface features.
Focuses on the crust layer.
Shows elevation: height of a surface feature.
452 Feet Above Sea Level

3. Topographic Maps
A drawing of the Earth’s surface (3D) on a flat piece of paper.
Shows elevation by using contour lines
Contour lines: connect all points at the same elevation.

4. SAME THING!

5. Contour Interval
Difference in elevation between adjacent (next to) contour lines.
If intervals are close together  means a steep hill/cliff.
If far apart  gentle rise

6. Rules Contour lines never cross.
The closer contour lines  steeper the slope.

7. Rules
Every 5th contour line is marked darker on a map, and elevation is marked with numbers.
