Which contour option allows you to adjust the frequency of contour lines?

In contour mapping, the frequency of contour lines is determined by the contour interval—the vertical difference in elevation between adjacent lines. A smaller interval creates more lines and finer detail because elevation changes are represented more often; a larger interval reduces the number of lines and smooths the map. The other options affect different aspects: index contour frequency changes how often a bold, labeled line appears but not the total count of lines; index contour line weight only alters the thickness of those bold lines; coloring contours by elevation changes how the lines are displayed colorwise, not how many lines there are.
