Detailed explanation-1: -Contours make it possible to show the height and shape of mountains, the depths of the ocean bottom, and the steepness of slopes. USGS topographic maps also show many other kinds of geographic features including roads, railroads, rivers, streams, lakes, boundaries, place or feature names, mountains, and much more.

Detailed explanation-2: -Topography is defined as the arrangement of features on the surface of the Earth. These features include land masses, oceans, islands, lakes, rivers, streams, mountains, hills, valleys, canyons, planes, plateaus, and volcanoes.

Detailed explanation-3: -Topographic maps conventionally show topography, or land contours, by means of contour lines. Contour lines are curves that connect contiguous points of the same altitude (isohypse). In other words, every point on the marked line of 100 m elevation is 100 m above mean sea level.

Detailed explanation-4: -The topography is the arrangement of the natural and artificial physical features of an area. For example, topography features the distribution of natural formations such as mountains, rivers, lakes, valleys, forests, glaciers, etc., and human-made features such as roads, dams, and cities.

Detailed explanation-5: -A river’s longitudinal profile, which is displayed in terms of elevation vs downstream distance, can be used to describe the topography of the river.

Detailed explanation-6: -Glaciers form ‘U’ shaped valley by erosion. As the ice melts hollows formed in mountains get filled up with water and form lakes (farn). The material carried by the glacier such as small and big rocks, sand and silt get deposited as a result hill like landform is formed which is called drumlin.
