⚠ EXAM TRAP Caspian Sea = world's largest LAKE (it's a saltwater lake, not a true sea); Lake Superior = largest FRESHWATER lake. Both are commonly confused since "Caspian Sea" has "Sea" in its name.

Driest DesertAtacama DesertChile
⚡ QUICK RECALL Three separate desert records: Antarctica = largest overall (cold desert), Sahara = largest hot desert, Atacama = driest. All three get tested as if they were one — keep them separate.

BuildingBurj KhalifaDubai, UAE — Height: ~828 m
⚠ EXAM TRAP Ojos del Salado's peak elevation is about 6,893 m (not its "average height" of 3,500 m as sometimes miswritten in notes) — it's the world's highest active volcano. Don't confuse elevation with base-to-summit relief.
World's Smallest

⚡ QUICK RECALL Vatican City = smallest COUNTRY. Australia = smallest CONTINENT. Two different scales — don't mix them in "smallest landmass" questions.
