Practice and Revision - Contours and Their Characteristics
Let us practise and revise what we learned about contours and their characteristics. Contour lines connect points of equal elevation on a ma
Core concept
Closely spaced contour lines indicate steep slopes, while widely spaced contour lines indicate gentle slopes.
How it works
V-shaped contours pointing uphill (away from higher ground) typically indicate a valley, while contours forming a closed loop indicate a hill or depression.
Why it matters
Contour intervals (the elevation difference between adjacent contour lines) are consistent on a given map, helping calculate elevation changes.
Key detail
Understanding contour patterns helps us visualise three-dimensional terrain from a two-dimensional map, essential for geography and outdoor navigation.
