Orinoco

The Orinoco (Spanish pronunciation: [oɾiˈnoko]) is one of the longest rivers in South America at 2,140 km (1,330 mi). Its drainage basin, sometimes known as the Orinoquia, covers approximately 1,000,000 km2 (390,000 sq mi), with 65% of it in Venezuela and 35% in Colombia. It is the fourth largest river in the world by discharge volume of water (39,000 m3/s (1,400,000 cu ft/s) at delta) due to the high precipitation throughout its catchment area (2,300 millimetres per are [0.084 in/sq ft]). The Orinoco River and its tributaries are the major transportation system for eastern and interior Venezuela and the Llanos of Colombia. The Guaviare River, with a flow of 8,200 cubic meters, is the main tributary. The environment and wildlife in the Orinoco's basin are extremely diverse.
