Topographic Map Features and Concepts

The video tutorial explains how contour lines on topographic maps represent landforms by joining points of equal altitude. It covers the interpretation of contour intervals and numbering, and how these lines indicate the height, shape, and steepness of landscape features. The tutorial also describes how to identify various landforms such as ridges, valleys, and slopes by analyzing the patterns of contour lines. Additionally, it discusses special landforms like cliffs, mesas, and passes, and how their contours are represented on maps.

What do contour lines on a topographic map represent?

• Weather patterns

• Temperature variations

• Altitude levels

• Population density

If contour lines on a map are increasing in number, what does it indicate?

• A downhill slope

• A valley

• A flat area

• An uphill slope

What does it mean when contour lines are close together?

• A steep slope

• A valley

• A flat area

• A gentle slope

How are valleys represented on a topographic map?

• V-shaped contour lines pointing downhill

• Round contour lines

• Elongated contour lines

• V-shaped contour lines pointing uphill

What type of slope has contour lines that are close together at lower heights and further apart as you move upslope?

• Concave slope

• Flat slope

• Convex slope

• Stepped slope

What is indicated by superimposed contour lines on a map?

• A gentle slope

• A cliff

• A valley

• A ridge

What feature is formed when a river flows over a cliff?

• A valley

• A waterfall

• A gorge

• A mesa

What is the difference between a mesa and a butte?

• A mesa has a larger flat top than a butte

• A butte has a larger flat top than a mesa

• A butte is wider than a mesa

• A mesa is taller than a butte

What is a saddle in topographic terms?

• A gentle dip between two high points

• A flat area

• A narrow ridge

• A steep slope

How is a pass different from a saddle?

• A pass is a steep slope

• A pass is a flat area

• A pass is a dip low enough for an easy route

• A pass is a narrow ridge
