Topographic Maps (Contour Interval)

Front

What is a contour interval?

Back

The contour interval is the vertical distance or difference in elevation between contour lines on a topographic map.

Front

What do contour lines represent on a topographic map?

Back

Contour lines represent points of equal elevation on a topographic map.

Front

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

Back

To determine the elevation, find the nearest contour line and use the contour interval to calculate the elevation.

Front

What is the purpose of a topographic map?

Back

Topographic maps are used to represent the three-dimensional features of the terrain in two dimensions, showing elevation, landforms, and other physical features.

Front

If the contour interval is 20 feet, what does that mean?

Back

It means that each contour line represents a change in elevation of 20 feet.

Front

What is the highest elevation if the highest contour line is 100 feet and the contour interval is 20 feet?

Back

The highest elevation is 100 feet.

Front

What are the different types of maps that show elevation?

Back

Topographic maps, physical maps, and relief maps show elevation.

Front

What does it mean if contour lines are close together?

Back

If contour lines are close together, it indicates a steep slope.

Front

What does it mean if contour lines are far apart?

Back

If contour lines are far apart, it indicates a gentle slope.

Front

What is the significance of sea level in topographic maps?

Back

Sea level is often used as a reference point for measuring elevation on topographic maps.
