(1 point) You are hiking the Inca Trail on the way to Machu Picchu. When you arrive at the highest point on the trail, which of the following are possibilities? In alphabetical order without punctuation or spacing, list the letters which indicate possibilities. (A) The path passes through the center of a set of concentric contour lines. (B) The path is tangent to a contour line. (C) The path follows a contour line. (D) The path crosses a contour line. Possibilities: AD

Explanation / Answer

The contour lines represent the difference in elevation of the point.

a) The highest point is at the center of the contour map and if one reaches to the top and then descends, the path of the journey will be traced through the center of contour.

b) The path is as well can be tangential to a certain contour line as at some point, one must travel along the circular path of the same elevation

c) It is possible that the path follows a contour line at a certain distance.

d) Since eventually one must travel to the top, there will be difference in between the elevation of one’s position. Therefore, the path will cross contour lines.

Hence, the possibilities are: ABCD
