which phrase describes a contour interval?\nplace where roads intersect a slope\nthick heavy lines on a topography map\nnumerical values of an areas elevation\nthe difference in elevation between two lines

Answer

Brief Explanations:

A contour interval is defined as the vertical distance or difference in elevation between successive contour lines on a topographic map. The first option is about road - slope intersections, the second is about contour lines themselves in terms of appearance, and the third is about elevation values of an area, not the difference between contour lines.

Answer:

the difference in elevation between two lines
