Exploring Earth’s Surface Chapter 1 Section 4
Standard • 6.2 Topography is reshaped by the weathering of rock and soil and by the transportation and deposition of sediment.
Anticipatory Set • Color the Contour map that was given to you according to the directions on the bottom.
Language of the Discipline • Topographical Maps • Contour Line • Contour interval • Index contour
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.
