What term is used for the imaginary lines that connect points of equal elevation on a map?

The term for the imaginary lines that connect points of equal elevation on a map is "Contour Lines." These lines are essential in topographic maps as they illustrate the shape and elevation of the terrain. Each contour line represents a specific elevation level, allowing map users to visualize the steepness of slopes, the height of hills, and the depth of valleys.

When the lines are close together, it indicates a steep elevation change, while wider spacing suggests a gradual slope. This tool is invaluable for hikers, geologists, and urban planners, as it helps in understanding the physical features of the landscape. Other terms like Meridian Lines, Prime Lines, and Latitude Lines refer to different geographical concepts. Meridian Lines relate to the longitudinal lines that run from the North Pole to the South Pole, Prime Lines is not a recognized term in geographic terms, and Latitude Lines are horizontal lines that measure distance north or south of the equator.
