General KnowledgeGeography
- AA snow covered mountain
- BA barren rocky piedmont surface
- CA sandy desert
- DA mangrove forest
Explanation
Fresh snow has the highest albedo of common land surfaces, about 0.80–0.90 — it reflects most incoming solar radiation. Sandy deserts (≈0.35), barren rock (≈0.2–0.3) and forests (≈0.1–0.15) reflect far less.
