What type of drawing shows the contour of land?

The correct answer is that a site plan shows the contour of land. A site plan is specifically designed to depict the arrangement and features of the land on which a structure is to be built or exists, including natural topography, structures, pathways, and other significant site elements. The contour lines on a site plan indicate changes in elevation and help in understanding the lay of the land, which is critical for grading, drainage, and landscape design.

Other types of drawings, such as elevation drawings, are focused more on the vertical aspects of a structure and do not show the land's contour. Similarly, floor plans depict the layout of rooms and spaces within a building, while detail drawings provide intricate information about particular components or connections in construction but do not contain information about land contours. Therefore, a site plan is the most suitable drawing type for demonstrating the contour of the land.
