Niagara Falls
540 x 540 JPEG
Published May 20, 2001
The Niagara River forms the U.S.-Canadian Border and allows Lake Erie to drain northwest into Lake Ontario. Lake Ontario is about 100 m lower than Lake Erie; the Falls and the rapids account for most of the elevation difference. The energy derived from water falling over the falls, with average total flows of 750,000 U.S. gallons (2.8 million liters) per second, fuel multiple power plants on the river. Power Plants downstream from the plant generate 4.4 million kilowatts of power for both Ontario and New York.

Dhaulagiri, Himalaya
540 x 339 JPEG
Dhaulagiri, seventh-highest peak in the world (26,794 ft/8167 m), dominates the skyline in this image taken by the Expedition 1 crew from the International Space Station using a high-magnification lens. Although it looks like a view from a high-altitude airplane, the photograph was taken out of the window of the Space Station from an orbital altitude of 200 nautical miles (370 kilometers). The view is southeastward across the southern Tibetan Plateau of China, to the Dhaulagiri Range of the Himalayas in central Nepal. The upper reaches of the more than 1,500-mile-long Brahmaputra River, which enters the Indian Ocean near Calcutta, are within the broad, high (about 17,000 feet) valley in the foreground. Uplift of the Himalayas continues today, at a rate of several millimeters per year, in response to the continuing collision of India with Eurasia that began about 70 million years ago.
