Question

1. steep areas have contour lines that are (far apart or close together) ______.
2. flat areas have contour lines that are (far apart or close together) ______.

Explanation:

Question 27:

In geography (a subfield of Natural Science), contour lines represent elevation. Steep slopes mean a rapid change in elevation over a short horizontal distance, so contour lines are close together.

Question 28:

Flat areas have little change in elevation over a horizontal distance, so contour lines are far apart as the elevation changes slowly.

Answer:

1. close together
2. far apart
