Official UPSC Answer KeyUPSC Prelims 1997 • Geography

Correct Answer: Option (B) — Isopleth map

Concept & Option Breakdown

Standard Reference Verified

An isopleth map displays lines of equal value for continuous variables across a geographic surface. Examples include isobars (equal atmospheric pressure), isotherms (equal temperature), and isohyets (equal rainfall). In contrast, a choropleth map uses shading within predefined administrative boundaries, while chorochromatic maps use distinct colors to classify qualitative area data (such as vegetation types).

Elimination Heuristic & Exam Approach

'Iso' means equal and 'pleth' means quantity/measure. Any map using isolines (isobars, isotherms, contours) is an isopleth map.
