Review: Reading a topographic map

What is a topographic map?

A map that represents terrain relief using contour lines to show elevation.

Define contour line.

A line on a map connecting points of equal elevation.

What does a close contour line indicate?

Steep terrain, as the elevation changes rapidly.

True or false: Topographic maps only show elevation.

False, because they also display land features like rivers and roads.

Difference between a hill and a mountain on a map.

Hills are lower in elevation than mountains and usually have gentler slopes.

What is elevation?

Fill in the blank: A _____ shows the steepness of terrain.

slope

What is a benchmark?

A point of known elevation used for reference on a map.

Define relief.

The difference in elevation between the highest and lowest points in an area.

What do index contours provide?

Elevation values at specific intervals, helping to read the map more easily.

True or false: Contour lines can cross each other.

False, because crossing lines would indicate an impossible elevation.

What is a depression contour?

A contour line with hachures that indicates a lower area or hollow.

What is a scale in map reading?

A ratio that shows the relationship between map distance and actual distance.

Difference between a physical and political map.

Physical maps display terrain features; political maps show boundaries and locations.

What is a slope?

The steepness or angle of a landform measured from a horizontal plane.

What do contour intervals indicate?

The vertical distance between consecutive contour lines.

What is a map key or legend?

A section that explains the symbols and colors used on the map.

True or false: Topographic maps can help in planning hiking routes.

True, because they display elevation changes and terrain features.
