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?
