Topographic Maps

Front

What is a topographic map?

Back

A topographic map is a detailed and accurate graphic representation of the features of a specific area, showing elevation, terrain, and landforms using contour lines.

Front

What do contour lines represent on a topographic map?

Back

Contour lines represent areas of equal elevation on a topographic map, indicating the height of the land above sea level.

Front

What is a contour interval?

Back

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

Front

If the contour interval is 10 feet, what is the highest possible elevation of a mountain with a peak at 69 ft?

Back

69 ft is the highest elevation, as it is the peak height indicated by the contour lines.

Front

What does it indicate when contour lines are close together?

Back

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

Front

What does it indicate when contour lines are far apart?

Back

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

Front

What is a topographic profile?

Back

A topographic profile is a cross-sectional view of the terrain, showing the elevation changes along a specific line drawn on a topographic map.

Front

How do you represent a hilltop in a topographic profile?

Back

In a topographic profile, you should curve your line above the points at the top of the hill.

Front

What is the formula to calculate gradient?

Back

Gradient = (Change in elevation) / (Distance traveled).

Front

If you hike 3.3 miles and your elevation increases from 2500 ft to 3100 ft, what is the gradient?

Back

The gradient is 181.8 ft/mi.
