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 does a contour line represent on a topographic map?

Back

A contour line represents a line on a map that connects points of equal elevation.

Front

What is the contour interval?

Back

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

Front

How do you calculate the gradient?

Back

Gradient is calculated by dividing the change in elevation by the distance traveled, typically expressed in feet per mile.

Front

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

Back

Slope refers to the steepness or degree of incline of a terrain, often represented by the gradient.

Front

What is an isotherm?

Back

An isotherm is a line on a map that connects points of equal temperature.

Front

How do you draw a topographic profile?

Back

To draw a topographic profile, plot the elevation points on a graph and connect them to represent the terrain's shape.

Front

What should you do when drawing a profile over a hill?

Back

When drawing a profile over a hill, curve your line above the points at the top of the hill.

Front

What is the purpose of contour lines?

Back

Contour lines are used to represent the elevation and shape of the terrain on a map.

Front

What does a closely spaced contour line indicate?

Back

Closely spaced contour lines indicate a steep slope.
