Conventional signs and symbols II - SS2 Geography Lesson Note

Escarpment: An escarpment is a steep slope or long cliff that separates two relatively level areas. On maps, it's depicted as a line with one side showing a sudden change in elevation, usually marked by contour lines that are close together on one side and farther apart on the other, indicating a dramatic change in terrain.

 

Plateau: A plateau is a flat, elevated area that is often surrounded by steep slopes. On maps, plateaus are represented by contour lines that form a series of roughly parallel lines at a consistent elevation, indicating the flat, high terrain.

 

Dissected Plateau: A dissected plateau is a plateau that has been eroded or cut into by rivers or other natural forces, creating a network of valleys and ridges. On maps, this is shown by contour lines that are closely spaced and irregular, indicating the varied terrain.

 

Ridge: A ridge is a long, narrow elevation or raised area along the top of a hill or mountain. On maps, ridges are depicted as lines with contour lines on either side, representing the high ground with slopes descending on each side.

 

Cliff: A cliff is a vertical or near-vertical rock face that drops abruptly from higher ground to lower ground. On maps, cliffs are typically represented as short, parallel lines perpendicular to contour lines, indicating a sudden change in elevation.
