elevation above mean sea level
a TOPOGRAPHICAL MAP shows the contour of the lines
A contour chart is a map that shows contour lines. A good example of this is a topographic map.

topographic maps
Closely spaced contour line on a topographic map shows that the land is steep.
When contour lines are close together the land is steep
Contour lines represent connecting points of equal elevation on a topographic map.
Topographical Map
A Topographic Map includes contour lines drawn to represent changes in elevation.The most important thing to remember is that CLOSE contour lines mean STEEP terrain and OPEN contour lines mean FLAT terrain.
A physical map shows mountains, hills, and plains through shading or contour lines. This type of map uses color gradients or elevation contour lines to depict the topography of an area.
Contour lines are lines that connect points of equal elevation. A topographical map is a map that uses contour lines to represent the elevation of land surfaces.
