GEOLOGY

Detailed explanation-1: -Topographic maps show the elevation of different landforms above sea level.

Detailed explanation-2: -The distinctive characteristic of a topographic map is the use of elevation contour lines to show the shape of the Earth’s surface. Elevation contours are imaginary lines connecting points having the same elevation on the surface of the land above or below a reference surface, which is usually mean sea level.

Detailed explanation-3: -Topographical maps, also known as general purpose maps, are drawn at relatively large scales. These maps show important natural and cultural features such as relief, vegetation, water bodies, cultivated land, settlements, and transportation networks, etc.

Detailed explanation-4: -Topographic maps are also called toposheets.

Detailed explanation-5: -Typical example of a land surface represented by a topographic map. The contour interval is 5 feet, and the highest point (elevation 760+ feet) is located near the center of the map.
