Question

The contour interval is:a) the heavier contour lines with elevations printed on them b) the difference in elevation between two adjacent contours c) the rate at which the land elevation changes a coordinate system with perpendicular lines of uniform spacing

Answer 1

b) the difference in elevation between two adjacent contours

Step-by-step explanation:

Each contour line corresponds to a particular elevation above some reference, usually sea level. The difference in elevations represented by adjacent contour lines is called the contour interval.
