World Geography

📖 Why World Geography matters for UPSC

World Geography questions are frequently current-affairs linked — a country or region in the news (due to conflict, trade agreements, or natural disasters) often becomes the basis for a map-based or physical-geography question. This topic is best studied alongside current events rather than in isolation.

🌍 Continents — a quick overview

• Asia — largest and most populous continent; home to the Himalayas, the world's largest mountain range.
• Africa — second largest continent; home to the Sahara (largest hot desert) and the Nile (traditionally considered the world's longest river).
• Europe — smaller in area but historically influential; the Alps are its major mountain system.
• North America — includes the Rocky Mountains and the Great Lakes, the largest group of freshwater lakes by area.
• South America — home to the Amazon Rainforest (largest tropical rainforest) and the Andes (longest mountain range).
• Australia — smallest continent; largely arid, with the Great Barrier Reef, the world's largest coral reef system.
• Antarctica — coldest, driest, and windiest continent; no permanent human population.

🗺️ Studying this topic effectively

Rather than memorising isolated facts, connect each region to recent news — conflicts, trade routes, resource discoveries, or climate events — since that's usually how these questions are framed in current exams.
