Topographic map showing the Afar Triangle which correlates to the shaded area in the location map shown above The Afar Triangle also called the Afar Depression is a geological depression caused by the Afar Triple Junction which is part of the Great Rift Valley in East Africa.

Contour lines on a map depict a spur with the U or V pointing away from high ground. You find the contour interval for your map in its legend. On some maps cartographers use teeth marks or hachures for depressions at craters or volcanoes because it marks the elevation goes up or down.

What is a depression on a map. Depressions Contour lines that show a depression crater or sinkhole on a map are represented by dashed lines hachure marks on the inside of a contour line. Closed contours with hatchures short lines pointing toward the center of the closure represent closed depressions.

Irregular circles are used to represent hills mountain summits knolls horns etc. So look what weve done - weve made up a new type of contour called a DEPRESSION CONTOUR. A topographic map is a type of map characterized by large-scale detail and quantitative representation of relief usually using contour lines in modern mapping but historically using a variety of methods.

Each number represents a different elevation the higher the number the higher the elevation duh and vice versa. 10022014 The volcanos topo map Click 34. Just the opposite of ordinary unhachured contours.

26012015 The closer together the inclines the steeper the hill. It could be described as an area of low ground surrounded by higher ground in all directions or simply a hole in the ground. You should also see elevations decreasing as you get near the depression.

30092013 Topographic maps show. If there is a HILL or DEPRESSION. Closed contours appearing on the map as ellipses or circles represent hills.

Its marked with little teeth called HACHURES. Usually only depressions that are equal to or greater than the contour interval will be shown. The elevation of the first depression contour is the same as the nearest regular contour line.

A contour line is a line drawn on a topographic map to indicate ground elevation or depression. A depression is a low point in the ground which is surrounded by higher ground in all directions. So if we look at the top of.

Another way to tell elevation is the numbers on the map. Sabkha of El Qattara Depression topographic map elevation relief. Contours make it possible to.

On the other hand the farther apart lines tend to indicate a depression in the landscape. And this isnt just any depression. Examples of depressions include volcanic craters sinkholes pit craters and impact craters.

Contours are imag-inary lines that join points of equal elevation on the surface of the land above or below a reference surface such as mean sea level.
