Question

How do contour lines show different slopes of land?

Answer 1

1. Elevation of land: The height of a contour is indicated by figures inserted in a break in the line.
2. Steepness of its slope: Contours that are fairly close together suggest steep slopes. Slopes steadily increase when they are farther apart. The absence of contour lines implies that the ground is flat or low.
3. Shape of land at various heights: The contour lines represent the shape of the land. Lakes are represented by roughly circular contours with decreasing values inside.
