what importance do the contours hold in topographic map
Answers
Answer:
contours are important
The topography of land can dictate where you place certain parts of your building, help you understand how the area will drain, and help you get a sense of how difficult it will be to build. But, that isn’t their
Elevations on a topo map are marked with contour lines, which connect points of equal elevation. Imagine walking around a mountain in a circle, never going uphill and never going downhill but staying at the same altitude. If you traced the path you walked, you would have a contour line on a map. Contour lines are typically separated by 40 vertical feet, though you should check the map you're using to be sure, and every fifth contour line is usually marked with an actual elevation.
Earth's surface has many different kinds of landforms that vary widely in height and elevation. Contour maps show the elevations of these surface features, which allows you to look at a two-dimensional map to visualize the Earth in three dimensions
The purpose of contour lines is to represent the tridimensional shape of the terrestrial surface on a bidimensional map. Contour lines are the intersection of an horizontal plane parallel to the reference level and the topographical surface to describe. Consequently: Contour lines are always closed curves
Contour lines on your map are used to display elevation. Every point that is at that height creates a circle around the elevation on the map
