The method of showing relief features through contour is very useful and versatile. In this hands-on activity, students will build mountains with clay and map them first with profile views, then hachures, and finally with contour lines. or It is a drawing which represents physical features. These maps depict in detail ground relief (landforms and terrain), drainage (lakes and rivers), forest cover, administrative areas, populated areas, transportation routes and facilities (including roads and railways), and other man-made features. the height above sea level of a point on Earth's surface. Elevation and Contour Lines: Elevation, typically measured relative to sea level whose elevation is arbitrarily said to be zero, is represented by contour lines on topographic maps. By reading contour interval it is easy to determine the different elevation of the landscape. All of the above landforms will not occur on all topographic maps, but many of them will occur on such maps. Reading Topographic Maps.

The symbols that represent map features are found in the legend. Learning to identify common contour line formations will help you read topo maps quickly, and recognize the various terrain features they represent on a map. Slopes and landforms. Topographic elevations and bathymetric depths are often shown on maps with contour lines. They can also be use for navigation by comparing the map to the landscape. . A line that represents such an outline. The contours form patterns that show you how steep the slopes are: the closer the contour lines are together, the steeper the slope will be.
