Standard6.2 Topography is
reshaped by the weathering of rock and soil and by the transportation and deposition of sediment.

Mapping (Input) Mapmakers use contour lines to represent
elevation, relief, and slope on topographical maps
Contour line- connects points of equal elevation
Contour interval- the change in elevation from contour line to contour line
Look at page 29 Index contours- labeled with the elevation in
round units. How any meters above sea level

Topographic Maps (Input)
Used to identify landforms To read a topographic map, may must
familiarize yourself with the map’s scale and symbols and interpret the map’s contour lines

Scales, Symbols, Interpreting Contour
Lines Scales- use large scale maps
Close up view of Earth’s surface Symbols used to show houses and other small features
Symbols What symbols would you use to represent a forest,
campground, swamp, or school? Interpreting Contour lines
Find the elevation of a feature, begin at the index contour (heavier line), then count the number of contour lines up or down to the feature.

Interpreting Contour Lines
Closely spaced lines- steep slopes Widely spaced lines- gentle slopes/flatter
areas It also helps to show ridges and valleys. (V
shaped) If they point downhill it is showing a ridge If they point uphill it is showing a valley A stream will flow towards to the opening
at the end of the V.
