What type of line connects points of equal elevation on a map?

• A. Grid line
• B. Contour line
• C. Base line
• D. Reference line

Answer: (B)

The correct choice is the type of line that connects points of equal elevation on a map, known as a contour line. Contour lines are essential in topographic mapping as they provide critical information about the terrain's elevation changes. Each contour line represents a specific elevation level, and the spacing between lines indicates the steepness of the terrain; closely spaced lines suggest steep slopes, while wider spaced lines indicate gentler slopes. Understanding contour lines is vital for navigation, land use planning, and outdoor activities like hiking, as they give a clear representation of the landscape's three-dimensional features on a two-dimensional map.
