What they show… Changes in elevation of Earth’s surfaceNatural features (mountains, lakes, etc.) Man made features (cities, roads, etc.)
Topo Terms… Contour lines – lines on a map that connect points of equal elevation Elevation – height above sea level
Topo Terms (cont’d.)… Contour interval – difference in elevation between 2 adjacent (side-by-side) contour lines Index contours – contour lines that are labeled to help you find the contour interval
Topo Terms (cont’d.)… Map scale – compares distances on the map with distances on the Earth Legend – explains symbols used on the map Benchmark – point of known elevation
Rules to Remember… Contour lines NEVER touch or crossContour lines make closed circles around hills and depressions for example…
Rules to Remember… Hachure lines are used to show depressionsfor example….
Rules to Remember… Contour lines form V’s that point to lower elevations when they cross a ridge Contour lines form V’s that point to higher elevations when they cross a stream for example…
Reading a Topo… Determine the contour interval Determine the map scaleIdentify any hills or depressions Use the legend to identify man made features
Topo Profile… A cross section picture of the land surfaceDetermined by graphing contour lines Shows changes in elevation across a certain portion of the map
Topographic Maps Mr. King.
Topographic Maps Obj- 7. Describe how contour lines and contour intervals are used to show elevation on topographic maps 8. List the 5 rules of topographic.

Modern technology has changed the way we view and map Earth.

By Megan and Slade. A topographic map is a map that shoes the surface features, or topography, of the Earth. Topographic maps show both natural features,
Topographic Maps TOPOGRAPHIC MAPS.
Topographic Maps specialized maps which show the highs and lows (relief) of the Earth’s surface.
Topographic Maps A Topographic map, or contour map is used to show the shape of the Earth’s surface. Elevation is the height above or below sea level.
