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

Front

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

Back

You can determine the elevation of a point by looking at the nearest contour line and its labeled elevation.

Front

What does a closely spaced contour line indicate?

Back

Closely spaced contour lines indicate a steep slope or a sharp change in elevation.

Front

What does a widely spaced contour line indicate?

Back

Widely spaced contour lines indicate a gentle slope or a gradual change in elevation.

Front

What is the significance of the index contour on a topographic map?

Back

Index contours are the darker, thicker lines that are labeled with their elevation, helping to easily identify elevation changes.

Front

How can you identify a peak on a topographic map?

Back

A peak is identified by a closed contour line with no other lines inside it, indicating the highest point in that area.

Front

What is the purpose of a scale on a topographic map?

Back

The scale shows the relationship between distances on the map and actual distances on the ground, allowing for accurate measurement.

Front

What is gradient in the context of topographic maps?

Back

Gradient refers to the slope or steepness of the terrain, calculated as the change in elevation over the distance.

Front

How do you find the easiest walking path on a topographic map?

Back

The easiest walking path is typically along the path with the gentlest slope, which can be determined by analyzing the spacing of contour lines.
