World Geography — Continents, Oceans, Landforms & Global Climates

World geography explores the physical dynamics, geomorphological structures, and climatic systems that govern the Earth’s terrestrial and oceanic environments. The planet’s physical framework is shaped by endogenic plate tectonics creating major fold mountain belts like the Andes and Himalayas, volcanic rings such as the Pacific Ring of Fire, and extensive rift valleys and plateaus. Exogenic forces—driven by fluvial systems like the Amazon and Nile, glacial carving, and aeolian erosion—continually sculpt landforms across hyper-arid deserts and fertile alluvial basins. Atmospheric circulation, ocean currents like the Gulf Stream, and solar insolation create distinct global climate zones classified under the Köppen system, while vital maritime chokepoints including the Suez Canal, Panama Canal, and Strait of Malacca dictate international navigation and global commerce.
