Mapping Earth Review

Front

What is a topographic map?

Back

A topographic map is a detailed and accurate graphic representation of features that appear on the Earth's surface, including elevation, terrain, and landforms.

Front

What do contour lines represent on a map?

Back

Contour lines represent areas of equal elevation on a topographic map, showing the shape and elevation of the terrain.

Front

What is the purpose of index contours?

Back

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

Front

How can you determine the steepness of a slope on a topographic map?

Back

The steepness of a slope can be determined by the closeness of contour lines; closer lines indicate a steeper slope.

Front

What does it mean if contour lines form a 'V' shape pointing upstream?

Back

If contour lines form a 'V' shape pointing upstream, it indicates the direction of water flow in a stream or river.

Front

What is elevation?

Back

Elevation is the height of a point on the Earth's surface above sea level.

Front

How do you identify the highest point on a topographic map?

Back

The highest point on a topographic map is indicated by the highest contour line, which is usually closed and has no other lines inside it.

Front

What is a contour interval?

Back

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

Front

What does it mean if a contour line is spaced far apart?

Back

If contour lines are spaced far apart, it indicates a gentle slope; if they are close together, it indicates a steep slope.

Front

What is the significance of the direction of stream flow on a topographic map?

Back

The direction of stream flow is important for understanding drainage patterns and watershed boundaries.
