Contours

Contours are lines on a map that connect points of equal elevation above sea level. They help visualize the shape and steepness of the terrain, such as hills and valleys. When contours are close together, it indicates a steep area, while wider spacing means a gentler slope. Contour maps are useful in various fields, including geography, architecture, and outdoor activities like hiking, as they provide insights into the landscape and help users understand elevation changes in any given area.
