Topographic maps

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 topographic map?

Back

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

Front

What is the purpose of contour intervals?

Back

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

Front

How can you identify a steep slope on a topographic map?

Back

A steep slope is indicated by closely spaced contour lines, while widely spaced lines indicate a gentle slope.

Front

What does the term 'elevation' mean?

Back

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

Front

What is the significance of a benchmark on a topographic map?

Back

A benchmark is a point of known elevation used as a reference for measuring elevation changes on a topographic map.

Front

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

Back

To determine the elevation of a point, locate the nearest contour line and read the elevation value associated with it.

Front

What features can be identified using a topographic map?

Back

Features such as mountains, valleys, rivers, cliffs, and roads can be identified using a topographic map.

Front

What is a profile view in relation to topographic maps?

Back

A profile view is a side view of the terrain, showing the elevation changes along a specific line on the map.

Front

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

Back

A hill is a raised area of land that is lower than a mountain, which is typically higher and more prominent.
