Topographic Maps
• Topographic maps show the surface features of a location.• They include rivers, hills, roads, and
more.• A topographic map also shows
elevation = height above sea level.

Topographic Maps The lines show the contours and elevation of the island.

Elevation on Topographic Maps
• Contour Lines are used to show elevation.• Contour Lines are the wavy lines and each line
represents a new elevation (height from sea level).
• The difference in elevation between one contour line and the next is called the contour interval.
• Relief is the difference in elevation between the highest and lowest points of the area being mapped.

Landforms on Topographic Maps
• Contour lines spaced widely apart indicate a gradual change in elevation, whereas lines close together indicate and rapid change in elevation or a steep slope.• A ‘V’ shape indicates a valley, the
point is the highest end.

Geologic Maps• Geologic maps show types of rocks and the
locations of faults, folds, and other structures.
• Geologic Units are a volume (section) of rock from the same age range and rock type and are shown in the same color.
• Letters are also used to label the types and ages of the rock on the map.
• Used by engineers, geologists, developers

Geologic Maps
• Contact Lines—places at which 2 geologic units meet.
• The place at which 2 geological units meet is called a “Contact”. – 2 main types of Contacts are: faults and
depositional contacts (one layer of rock formed on top of another)
