Drainage basins of the world’s longest rivers mapped

Most of our Earth’s surface is coated in water, but only less than one percent of it is freshwater. The total water volume in rivers is measured at 2,120 cu km (510 cu mi), or only 0.49 percent of the surface fresh water on the planet!

But notwithstanding this fact, rivers have played and still play an essential role in civilization progress.

Rivers are the result of numerous compounding water inflows gained within a drainage basin. A drainage basin is defined as the land area where precipitation collects and drains off, feeding rivers and their tributaries.

The map below created by Reddit user CountZapolai shows how large the drainage basins can be for the world’s longest rivers.

Drainage basins of the world's longest rivers

The longer a river system becomes, the more territory it passes through. As a result, long rivers have extensive drainage basins.

The Amazon river has the most extensive basin system worldwide, covering one-third of the whole continent of South America. The 10 longest rivers of the Earth covering a land area equivalent to Africa.

Find cities with similar climate

This map has been created using The Global environmental stratification. The Global environmental stratification (GEnS), based on statistical clustering of bioclimate data (WorldClim). GEnS, consists of 125 strata, which have been aggregated into 18 global environmental zones (labeled A to R) based on the dendrogram.

The Appalachian Mountains, the Scottish Highlands, and the Atlas Mounts in Africa were the same mountain range

The Central Pangean Mountains was a prominent mountain ridge in the central part of the supercontinent Pangaea that extends across the continent from northeast to southwest through the Carboniferous , Permian Triassic periods. The mountains were formed due to a collision within the supercontinents Gondwana and Laurussia during the creation of Pangaea. It was comparable to the present Himalayas at its highest peak during the start of the Permian period. It isn’t easy to assume now that once upon a time that the Scottish Highlands, The Appalachian Mountains, the Ouachita Mountain Range, and the Atlas Mountains in northwestern Africa are the same mountains , once connected as the Central Pangean Mountains.

Moose population in North America

The moose population in North America is shrinking swiftly. This decrease has been correlated to the opening of roadways and landscapes into this animal's north range.   In North America, the moose range includes almost all of Canada and Alaska, the northern part of New England and New York, the upper Rocky Mountains, northern Minnesota and Wisconsin, Michigan's Upper Peninsula, and Isle Royale.    In 2014-2015, the North American moose population was measured at around one million animals. The most abundant moose population (about 700,000) lives in Canada. About 300 000 moose remains in nineteen U.S. states Alaska, Colorado, Connecticut, Idaho, Maine, Massachusetts, Minnesota, Montana, Michigan, Nevada, New Hampshire, New York, North Dakota, Oregon, Utah, Vermont, Washington, Wisconsin, and Wyoming. The largest moose specimens are found in Alaska 200 thousand moose. Below the map shows the size of US states scaled by the moose population.     Via www.vividmaps.com
