What are imaginary lines that connect points of equal elevation on a map called?

• A. Elevation markers
• B. Contour lines
• C. Topographic lines
• D. Gradient lines

Answer: (B)

The correct answer is based on the definition and purpose of contour lines in cartography. Contour lines are used on maps to represent locations that share the same elevation above a specific reference point, usually sea level. By connecting these points, contour lines create a visual representation of the terrain's shape and steepness. In addition to indicating elevation, contour lines can also help users understand various landforms, such as hills, valleys, and slopes. The spacing of the contour lines provides information about the steepness of the terrain; closely spaced lines indicate a steep slope, while widely spaced lines signify a gentler slope. The other terms mentioned have different uses in geographic contexts: elevation markers refer to specific points indicating height but do not form a continuous line; topographic lines and gradient lines are not standard terms used in mapping as broadly recognized categories focused specifically on elevation like contour lines. Thus, contour lines is the precise term for imaginary lines connecting points of equal elevation on a map.
