Topographic Maps Review

Front

What is a topographic map?

Back

A topographic map is a detailed and accurate graphic representation of the features that appear on the Earth's surface, including elevation, terrain, and landforms.

Front

What do contour lines represent on a topographic map?

Back

Contour lines represent elevation and the shape of the terrain. Each line connects points of equal elevation.

Front

What does a close spacing of contour lines indicate?

Back

Close spacing of contour lines indicates a steep slope.

Front

What does a wide spacing of contour lines indicate?

Back

Wide spacing of contour lines indicates a gentle slope.

Front

What is the purpose of contour intervals?

Back

Contour intervals indicate the vertical distance between adjacent contour lines, helping to understand the elevation change.

Front

How can you determine the highest elevation on a topographic map?

Back

The highest elevation can be determined by identifying the highest contour line or point marked on the map.

Front

What do the V shapes on a topographic map indicate?

Back

The V shapes indicate the presence of a river or stream, with the point of the V pointing upstream.

Front

How do you find the elevation of a specific point on a topographic map?

Back

To find the elevation of a specific point, locate the nearest contour line and read the elevation value.

Front

What is the significance of index contours?

Back

Index contours are thicker contour lines that are labeled with their elevation, making it easier to read the map.

Front

What is a benchmark on a topographic map?

Back

A benchmark is a point of known elevation marked on the map, often indicated with a symbol and a specific elevation value.
