Topographic Maps Review

Front

What are topographic maps?

Back

Topographic maps are detailed representations of terrain that show elevation, landforms, and features such as rivers, roads, and buildings.

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 is the significance of closely spaced contour lines?

Back

Closely spaced contour lines indicate steep terrain, while widely spaced lines indicate gentle slopes.

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 read the elevation value marked on it.

Front

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

Back

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

Front

What does the term 'benchmark' mean in topography?

Back

A benchmark is a point of known elevation used as a reference for measuring other elevations.

Front

How can you identify a peak on a topographic map?

Back

A peak is identified by a closed contour line with the highest elevation value in the area.

Front

What is the difference between a hill and a mountain on a topographic map?

Back

A hill is a raised area with a rounded top, while a mountain is typically higher and more rugged.

Front

What does the term 'slope' refer to in topography?

Back

Slope refers to the steepness or degree of incline of the terrain, often measured in degrees.

Front

How can you find the direction of a river on a topographic map?

Back

Rivers flow downhill, so they typically flow from higher elevation to lower elevation, indicated by the contour lines.
