Question

which items are used to show elevation, relief, and slope on a topographic map? check all that apply. topographic lines contour lines index contours topographic symbols contour interval topographic interval index topography

Explanation:

• Contour lines (sometimes called topographic lines) connect points of equal elevation, directly showing elevation, relief, and slope via their spacing.
• Index contours are a subset of contour lines, labeled with elevation values to make reading elevation easier.
• The contour interval is the fixed elevation difference between adjacent contour lines, which is critical for calculating slope and relief.
• Topographic symbols typically represent man-made or natural features, not elevation/relief/slope. "Topographic interval" and "index topography" are not standard terms for this purpose.

Answer:

• topographic lines
• contour lines
• index contours
• contour interval
