Contour

In general knowledge, "contour" refers to the shape, outline, or surface form of an object or landscape. It describes how the surface varies in elevation or depth, highlighting features like hills, valleys, or human-made structures. In fields like geography or art, contours help depict and understand the three-dimensional qualities of a subject. Cartographers use contour lines on maps to represent elevation changes, allowing viewers to visualize the terrain. Overall, contours play a crucial role in our understanding of both natural and artificial environments, conveying essential information about shape and structure.
