Question

topographic map decoding independent practice

1. a student is tasked with determining the best path for a new trail that minimizes steep climbs while avoiding areas with highly fractured bedrock.

which combination of information is most critical to interpret?
mark only one oval.
only the magnetic declination and map projection details.
the color key from the topographic map and the legend from the geologic map.
the contour line spacing on the topographic map and the fault and fracture symbols on the geologic map.
the latitude and longitude lines from both maps.

• 1 point

1. which of the following can be seen on a geologic map *

mark only one oval.
contour lines
strike and dip measurements
gradient of a slope
airport landing strips
1 point

Explanation:

For question 10: Contour line spacing on a topographic map directly indicates slope steepness (closer lines = steeper slope, which needs to be minimized for the trail). Fault and fracture symbols on a geologic map mark areas with highly fractured bedrock, which must be avoided.
For question 11: Strike and Dip measurements are standard symbols on geologic maps to show the orientation of rock layers. Contour lines and slope gradients are features of topographic maps, while airport landing strips are not a standard geologic map feature.

Answer:

1. The contour line spacing on the topographic map and the fault and fracture symbols on the geologic map.
2. Strike and Dip measurements
