Contours refer to the outlines or shapes of an object, often used in art and design to define its form. When an artist draws a contour, they focus on the edges and details that make the object recognizable. This technique helps to create depth and dimension, allowing viewers to understand the object's structure more clearly. In geography, contours are lines on a map that connect points of equal elevation. These lines help to illustrate the shape of the land, showing hills, valleys, and slopes. By studying contour lines, hikers and explorers can better navigate terrains, making it easier to plan routes in areas like the Appalachian Mountains or the Rocky Mountains.
