What is the difference between contour lines and isolines?

What is the difference between contour lines and isolines?

Contour lines are specific types of isolines that connect points of equal elevation on a map, while isolines can represent various types of data, such as temperature or pressure.

Can you give me an example of an isoline?

Sure! An example of an isoline is a isotherm, which connects points of equal temperature on a weather map.

Are contour lines only used in topographic maps?

Yes, contour lines are primarily used in topographic maps to represent elevation, but they can also appear in other types of maps that show terrain.

How do I read contour lines on a map?

To read contour lines, look for the spacing between them: closely spaced lines indicate steep terrain, while widely spaced lines indicate gentle slopes.

What happens if contour lines cross each other?

If contour lines cross, it usually indicates a vertical cliff or an overhanging feature, which is a rare occurrence in topography.
