Answer:
The contour lines cross one another in a cliff because they indicate the change in elevation of the landmass. Contour lines are the lines that connect points of equal elevation on a topographic map. They are used to visualize the 3-dimensional surface of the Earth in 2 dimensions by depicting the height of the land above sea level. Contour lines cross one another in a cliff as the elevation changes rapidly along the cliff face. The closer the contour lines are to one another, the steeper the slope of the cliff is. When contour lines cross one another, it indicates a vertical cliff or overhang where the elevation changes abruptly.
