What are the differences between a topographic map and a road map?

2. Warm Up
What activity or assignment have you enjoyed the most so far in science and why?

3. Warm Up
What types of activities can you plan using a topographic map?

4. How do we map topography?

5. Topography Topography – the shape of the land
Topography is determined by:
Elevation – the height above sea level of a point on Earth’s surface
Relief – the difference in elevation between the highest and lowest points of an area
Landforms – a feature formed by the processes that shape the Earth

6. Types of Landforms Plain – low elevation and low relief
Mountain – high elevation and high relief
Plateau – high elevation with a mostly level surface

7. Topographic Maps
Shows the features (both natural and human made) of an area as if you were looking down on them from the air
Provide highly accurate information on the elevation, relief, and slope of the ground surface
Large scale – most are very detailed at 1:24,000 0r 1cm=.24 km

8. Topographic Maps
Symbols – there are many symbols that give information about the topography
Contour lines – connect areas of equal elevation
Contour interval – the change in elevation from contour line to contour line
Depression – a closed loop with lines pointing inward
