TOPO MAPS Shows elevation, change in elevation, rivers, towns, points of interest, sometimes roads. Useful when hiking. Elevation is given in feet above sea level
KEY TERMS CONTOUR LINE – lines that show equal elevation
KEY TERMS INDEX CONTOUR – darker line that gives elevation above sea level
KEY TERMS RELIEF – the difference in elevation between the highest and lowest points in an area.
KEY TERMS CONTOUR INTERVAL– the difference in elevation between contour lines
GOLDEN RULES RULE 1 – points on a contour line represent the same elevation
GOLDEN RULES RULE 2 – CLOSE contour lines = STEEP FAR APART contour lines = GENTLE
GOLDEN RULES RULE 3 – contour lines that cross a stream are V shaped. –The V points to upstream to higher elevation
GOLDEN RULES RULE 4 – = The tops of hills, mountains, peaks = depressions, where lines point to bottom of depression

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.
Topographic Maps. What they show… Changes in elevation of Earth’s surface Natural features (mountains, lakes, etc.) Man made features (cities, roads,
Chapter 3 Topographic Maps Topography Means: “Shape of the land”
Introduction to Topographic Maps. Topographic Maps Two dimensional model of the Earths surface (represents 3-D world) Topographic maps are also known.
A representation of the physical features of an area Reference Point – a fixed place on Earths surface from which direction and location can be described.

Topographic Maps. What is a Topographic Map? In contrast to most maps, a topographic map shows the shape of the Earths surface by using contour lines.
Maps Chapter 6, Section 3. Map Projections How is a map made? How is a map made? Points on a globe (3D) are transferred to paper (2D). May distort shapes.
Goals: 1. Differentiate between latitude and longitude. 2. Understand that a topographic map is a 2-D model that displays 3D information 3. Describe map.
Topography: Mapping the Surface of the Earth. Facts: The Earth’s surface is constantly changing. Forces responsible for these changes: –Plate Motion (caused.
