Study Notes
Understanding Topographic Maps
- Contour lines on a topographic map represent the same height or altitude
- These lines are like circles on a whipped cream or on a rock, connecting and forming circles when viewed from above
- Most topographic maps show these lines in a light brown color
- Index contours on the map display the exact elevation of specific lines, while other lines represent different elevations
- Contour lines have specific rules: they cannot cross and form circles around hills or depressions
- The contour interval is the distance between any two side-by-side lines, representing the elevation change
- The closer the contour lines, the steeper the hill; a sheer cliff would have tightly packed lines, while a gentle slope would have more spread out lines
- Contour lines form concentric circles around hills and mountains as elevation increases
- Hachures on a map indicate depressions or holes, such as volcano craters or dips in a landscape
- Geologic maps contain similar features to topographic maps
- Topographic maps use index contours to label specific elevations and avoid clutter
- Hachures are used to represent depressions, such as volcanoes or dips in the landscape
