If a topographic map included a 6,000 ft. mountain next to an area of low hills, which would best describe the contour lines on the map?
a.
the contour lines would be dark blue.
b.
the contour lines around the mountain would be very close together.
c.
the contour lines would cross near the top of the mountain.
d.
the contour lines around the rolling hills would be very close together.

The correct answer is - b. The contour lines around the mountain would be very close together.

If we have an area with low hills, and than a mountain next to them that suddenly lifts up to 6,000 ft, the contour lines will be very close to one another on the mountain.

The reason for that will that the contour lines on the low hills will be not sloe to one another, as their elevation is small, but than the mountain lifts up significantly next to them, so it means that it is a steep mountain, which will change the construction of the contour lines. Because the mountain will appear much steeper and much higher than its surroundings, the contour lines will appear much closer to one another compared with the others too. The steeper a mountain is, the closer the contour lines would be, and vice versa.
