Topographic maps Gradients and profiles

Front

What is a topographic map?

Back

A topographic map is a detailed and accurate graphic representation of cultural and natural features on the ground, showing elevation changes through contour lines.

Front

What are contour lines?

Back

Contour lines are lines on a topographic map that connect points of equal elevation, indicating the shape and elevation of the terrain.

Front

What does a steep gradient indicate on a topographic map?

Back

A steep gradient indicates a rapid change in elevation over a short distance, represented by closely spaced contour lines.

Front

What does a gentle gradient indicate on a topographic map?

Back

A gentle gradient indicates a gradual change in elevation over a longer distance, represented by widely spaced contour lines.

Front

How do you calculate the gradient between two points?

Back

Gradient = (Change in elevation) / (Horizontal distance)
