What are contour lines and why are they important?

Contour lines are lines on a map that connect points of equal elevation. They help in understanding the terrain.

How do contour lines indicate the steepness of a slope?

The closer the contour lines are to each other, the steeper the slope. Wider spacing indicates a gentler slope.

Can you explain how to read contour lines on a topographic map?

Sure! Start by identifying the contour interval, then look for the lines that form closed loops, which indicate hills or depressions.

What happens if contour lines cross each other?

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

Are contour lines used in any other fields besides geography?

Yes, contour lines are also used in fields like architecture, civil engineering, and environmental science to represent elevation changes.
