'Contour lines' on a topographic map cannot:
Choose the correct answer
Represent uniform slope on a hillside
Two contours of different elevation values can never merge or cross (except at a vertical cliff shown by special treatment)
Show valleys as V-shapes pointing uphill
Be closely spaced for steep terrain
Correct Answer
B. Two contours of different elevation values can never merge or cross (except at a vertical cliff shown by special treatment)
AI Detailed Explanation & IS Code Reference
Unlock the reasoning, formula path and code-linked notes inside your student dashboard.
Contour properties: (1) Each contour represents constant elevation; (2) Contours never cross each other (except overhanging cliff — shown dashed); (3) Closely spaced = steep slope; (4) Widely spaced = gentle slope; (5) V-shape pointing uphill = valley; V pointing downhill = ridge/spur. Contours CROSS at overhangs. Two different contours with different elevations NEVER merge on flat ground (would imply same elevation at two adjacent contour values).
