Week of Sept. 15
What you are looking at is a 3-D image of Glacier National Park with a topographic overlay.  A what?

Questions to consider:

1.  What are the differences between geological maps, topographic maps, aerial photographs, satellite images, and physical maps?
2.  What is topography?
3.  What does a topographic map show?
4.  What is the difference between relief and slope of the land?
5.  How do you use contour lines to find the contour interval?
6.  How can a topographic map help you identify landforms?

Types of maps:

Geological Map - show rock types and ages



Physical Map - shows land features


Topographic Map - shows the shape of the Earth's surface with lines that represent elevation

Satellite Images and aerial photography

Mississippi River Delta
O
Satellite Image - taken from orbiting satellite in space

Color Interpretation:  dark blue/black = ocean water, light blue - sediment and shallow waters, red (false-color) = vegetation

Aerial Photography - taken from somewhere in the atmosphere

Topo Activity 1


Directions:  Match the landform letters to its topo map numbers!



Topo Activity 1

Directions:  What is the contour interval of this topo map section? (Units will be in feet)
