Contour lines are lines connecting equal points of elevation on a site plan or map.

Contour lines are lines connecting equal points of elevation on a site plan or map.

• A. TRUE
• B. FALSE
• C. They connect points of equal latitude
• D. They indicate soil type

Answer: (A)

Contour lines show points that share the same elevation, revealing the shape of the terrain on a map or site plan. Each line represents a constant elevation, and the spacing between lines indicates slope: closely spaced lines mean steep terrain, while widely spaced lines indicate gentler slopes. They cannot cross each other and they are not related to latitude lines or soil types. This helps in planning for fire and emergency services by understanding access, drainage, and water supply needs based on the terrain.
