Land and People. Geographically Venezuela is a land of vivid contrasts, with four major divisions: the Venezuelan highlands, the coastal lowlands, the basin of the Orinoco River, and the Guiana Highlands.
The economy of Venezuela is largely based on the petroleum sector and manufacturing. Revenue from petroleum exports accounts for more than 50% of the country's GDP and roughly 95% of total exports. Venezuela is the fifth largest member of OPEC by oil production.
