Neva River, a river in northwestern Russia. It flows from Lake Ladoga westward into the Gulf of Finland, an arm of the Baltic Sea. Though only 46 miles (74 km) long, the river carries a large volume of water, as it is the major outlet of the lake. It is part of a canal and river system linking the Baltic Sea to the White Sea and the Volga River system. St. Petersburg is near the mouth of the river.
Central Asia, an indefinite region in the interior of Asia. It is generally considered to extend in a broad band from the Caspian Sea into the Xinjiang region of China, covering roughly the same area as Turkestan.
Tonle Sap, a lake in central Cambodia, drained by the Tonle Sap River. During the rainy season the lake receives water from many streams, mainly the flooding Mekong River, and greatly increases in size, inundating surrounding areas.
