PSLE Science Reality Lab Vol No.366 | “Contour Line = 100 m” — Is Everything Inside the Line Exactly 100 m High?
A massive Primary 5/6 PSLE Science Reality Lab guide to contour maps: why a 100 m contour labels equal elevation along the line, not every point inside it, and how spacing, interpolation and source data limit the claim.
