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 are contour lines?

Back

Contour lines are curved lines on a topographic map that connect points of equal elevation, indicating the shape and steepness of the terrain.

Front

What does it mean when contour lines are close together?

Back

When contour lines are close together, it indicates a steep slope or a steep change in elevation.

Front

What does it mean when contour lines are spaced far apart?

Back

When contour lines are spaced far apart, it indicates a gentle slope or a gradual change in elevation.

Front

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

Back

The elevation of a point on a topographic map can be determined by looking at the nearest contour line and its labeled elevation.

Front

What is the purpose of contour intervals on a topographic map?

Back

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

Front

What is the significance of the highest contour line on a topographic map?

Back

The highest contour line indicates the maximum elevation of the area before it drops off, often representing the peak of a hill or mountain.

Front

How can you identify the steepest slope on a topographic map?

Back

The steepest slope can be identified by the area where contour lines are closest together.

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 on the map.

Front

What does it mean if two locations on a topographic map are on the same contour line?

Back

If two locations are on the same contour line, it means they are at the same elevation.
