contour lines

Contour lines are lines drawn on a map that connect points of equal elevation above sea level. They help to illustrate the shape and steepness of the terrain; for example, closely spaced lines indicate a steep slope, while wider spaced lines suggest a gentler incline. Each line represents a specific height, allowing users to visualize the landscape and understand its features, such as hills, valleys, and plateaus. Contour lines are essential for activities like hiking, planning construction, and analyzing land for agriculture or conservation, providing a clear understanding of the area's topography.
