WUP:
TOC = “Objective – Day 3”
I will be able to interpret topographic maps to identify land and erosional features by taking notes and completing worksheets.
TOC = “Topo Notes”
Landforms – Feature of the Earth's surface, e.g. a valley, mountain, plain, volcano, sink hole, canyon, or river
Elevation – height above sea level
Contour Line – shows points of equal elevation
Topographic Map Shows shape (landforms) and elevation (height) of land by using contour lines
Topographic Map Name/locate features
Mountains
River or Canyon
Facts:-Topographical maps are looking down (like helicopter view)- 0 is sea level
Example Topographic Map:
Example Topographic profile:
view illustrating a cross-section.
Gradual slope – lines farther apart
Gradu
al
Steep
Steep slope – lines close together
Tick marks: indicate a depression (volcano or sink hole)
Water flows DOWN HillSouth is NOT Down
Some rivers flow north, some south some east and some west, but all flow towards the ocean and away from mountains
Determining River Flows:
1. The "V" shape contour lines points UPHILL
2. Water flows from higher elevation to lower elevation.
Path of water
What is the elevation for point:
A? B? C? D? E?
Which is higher, hill A or hill B?
Which is steeper, hill A or hill B?
How many feet of elevation are there between contour lines?
Which Topographic map best matches this cross-section profile?
Mountain - on left side - left steep (close lines)
Mountain - on right
Mountain - in middle
Mountain - in middle
What is the interval for Bonham Peak?
What is the highest point of elevation on the map?
What landform is located on the northeast corner of the map?
What side of the mountain would be easier to climb?

TOC = “Topo Map Drawing”
Draw this in your journal and then draw your interpretation of what it would look like from a side view.
On new page complete this drawing.
Draw this in your journal and then draw your interpretation of what it would look like from a side view.
Where is the cabin? Why there?
Which way would be easiest to climb hill?
What is the contour interval?
Which way is water flowing? Why?
Reflection:Tell how you might use a topographic map if you were selecting:
A route for a hike?
The best location for an airport?
A route for a new road?
