This photo shows one of the most impressive waterfalls in the world, Victoria Falls, located on the Zambia-Zimbabwe border in south central Africa. The falls are about 1 mile wide and plunge as much as 428 feet. Niagara Falls, by comparison, drop about 175 feet. The loud roar produced by the falls is perceptible from a distance of about 25 miles. Victoria Falls is said to be the world's largest sheet of falling water. The spray falls back as a permanent mist, which nourishes the luxuriant vegetation at the base of the falls. The British explorer, David Livingstone, visited the falls in 1855 and named them for Queen Victoria.
