top ten longest rivers: Nile (Africa) 6.693 km; Amazon (South America) 6.436 km; Mississippi-Missouri (North America) 6.238 km; Yenisey-Angara (Asia) 5.981 km; Ob-Irtysh (Asia) 5.569 km; Yangtze (Asia) 5.525 km; Yellow (Asia) 4.671 km; Amur (Asia) 4.352 km; Lena (Asia) 4.345 km; Congo (Africa) 4.344 km

note: rivers are not necessarily navigable along the entire length; if measured by volume, the Amazon is the largest river in the world, responsible for about 20% of the Earth's freshwater entering the ocean

top ten largest natural lakes (by surface area): Caspian Sea (Azerbaijan, Iran, Kazakhstan, Russia, Turkmenistan) 372.960 sq km; Lake Superior (Canada, United States) 82.414 sq km; Lake Victoria (Kenya, Tanzania, Uganda) 69.490 sq km; Lake Huron (Canada, United States) 59.596 sq km; Lake Michigan (United States) 57.441 sq km; Lake Tanganyika (Burundi, Democratic Republic of the Congo, Tanzania, Zambia) 32.890 sq km; Great Bear Lake (Canada) 31.800 sq km; Lake Baikal (Russia) 31.494 sq km; Lake Nyasa (Malawi, Mozambique, Tanzania) 30.044 sq km; Great Slave Lake (Canada) 28.400 sq km

note 1: the areas of the lakes are subject to seasonal variation; only the Caspian Sea is saline, the rest are fresh water

note 2: Lakes Huron and Michigan are technically a single lake because the flow of water between the Straits of Mackinac that connects the two lakes keeps their water levels at near-equilibrium; combined, Lake Huron-Michigan is the largest freshwater lake by surface area in the world
