What kind of topography is indicated by contour lines that are very close together? by contour lines that are very far apart?

If contours are close together it indicates a steep slope and if they are apart it means a relatively gentle or flat slope.

Explanation:

Topographic maps were created to depict the relief features and type of terrain on the map. The use of contour lines drawn on a map is done to show the lines of equal height of elevation. These lines tend to remain constant. Also, there are three types of contour lines on a map i.e the supplementary, Index and Intermediate. The dark brown color is used to show lines of high altitude and light brown lines represent low altitude. The more close the line is the steeper is the wall and the far the lines are less is the compactness and more is the gap.
