Question

1. base your answer on the topographic maps and block diagrams of two landscape regions shown below. the block diagrams show a three - dimensional view of the topographic maps directly above them. elevations are measured in feet. points a, b, c, and d are locations on earths surface. which contour interval is used on both topographic maps? 20 ft 10 ft 40 ft 30 ft

Explanation:

Step1: Analyze Landscape 1

In Landscape 1, the contour lines are labeled with values like \( 100\), \( 120\), \( 140\), etc. The difference between consecutive contour lines is \( 20\) feet.

Step2: Analyze Landscape 2

In Landscape 2, the contour lines are labeled with values like \( 200\), \( 220\), \( 240\), etc. The difference between consecutive contour lines is \( 20\) feet.

Answer:

A. \( 20\) ft
