Topo Map: Contour Lines

Topographic maps display the elevations and also slopes of hills, valleys, and various other naturalattributes by the use of contour lines.



*

Drawing Contour Lines

Draw a collection of contour lines on the map listed below using the elevations presented as a guide.The sea level elevation line is gave and you need to draw contour lines at intervals of20 meters.



Complete the Topography Map

Topographical maps are choose continuous maps in that they offer the geographical positions,but they additionally give elevations of both manmade and organic functions. Using the contourlines and contour intervals, provide a range for the elevations of the functions on thismap.


Features of Rivers

Rivers erode their networks and also as they carry out so they go through various steras ofadvance and also develop different features.


Flow of Rivers

Rivers frequently begin as a melting glacier or a collection of small streams high up in acollection of hills. As the river waters flow downhill they reshape the land also by eroding featuresand also carrying materials such as stones, sand, and clay. At some point the river ends in alake or the sea. The term river mechanism is provided to describe the river itself and also all thewater that flows into it.


Glacier Anatomy

Glaciers are large structures made of ice that progressively move dvery own the sides of ahill. As they carry out so, they carry tons of trapped rock and also scrape and grind thehill wall surfaces. The massive and sustained force reforms the mountain sides andslopes in its path and also leaves behind deposits of rock brought from various other locations.


Describing Latitude and Longitude

The lines of latitude and longitude are used to situate points of the surface of the Planet.The lines of latitude run from East to West and the lines of Longitude run from North toSouth.


Map Design

Maps are exceptionally practical tools, but using them appropriately needs discovering a number of aspectsof the way maps are made. Most maps have actually a number of attributes that are important for usingthem to their full potential, yet they are advantageous only if you recognize to usage their manyfeatures.
