Major World Rivers, Lakes & Waterfalls

Global hydrology encompasses continental drainage systems, freshwater and saline lake basins, and monumental waterfalls shaped by fluvial erosion and tectonic rift processes. The Nile River in northeastern Africa is traditionally recognized as the longest river in the world, while the Amazon River in South America discharges the greatest volume of water, carrying more runoff than the next seven largest rivers combined. In East Asia, the Yangtze (Chang Jiang) is the longest river in Asia. Significant lakes include Lake Baikal in Siberia (the world's deepest and oldest freshwater lake), Lake Superior (largest freshwater lake by surface area), and the Caspian Sea (largest inland enclosed water body). Angel Falls in Venezuela represents the highest uninterrupted waterfall.
