The Sahara Desert is a near-uninterrupted brown band of sand and scrub across the northern third of Africa. The Amazon rain forest is a dense green mass of humid jungle that covers northeast South America. But after strong winds sweep across the Sahara, a tan cloud rises in the air, stretches between the continents, and ties together the desert and the jungle. It’s dust. And lots of it. For the first time, a NASA satellite has quantified in three dimensions how much dust makes this trans-Atlantic journey. Scientists have not only measured the volume of dust, they have also calculated how much phosphorus – remnant in Saharan sands from part of the desert’s past as a lake bed – gets carried across the ocean from one of the planet’s most desolate places to one of its most fertile.
The Victoria Falls is called “Mosi-oa-Tunya” by the local people, the smoke that thunders, and constitutes one of the best spectacular natural wonders of the world. With its 1708 meters wide became it in the largest curtain of water in the world also by its remarkable falls. The waterfall is situated in southern Africa on the Zambezi River between the countries of Zambia and Zimbabwe. It boasts of being the largest waterfall in the world with the most unusual in form and having the most diverse and easily seen wildlife of any major waterfall site.
The Victoria Falls still inspires visitors as it did with David Livingstone in the 1860s. The falls and surrounding area of this remarkable preserved natural state have been declared National Parks and a World Heritage Site, thus preserving the area from excessive commercialization.
Two cities are part of Victoria Falls: at the eastern end of it, Victoria Falls town in Zimbabwe lies on the southern bank of the Zambezi River and at 18km south of town, Victoria Falls Airport has international services to Johannesburg and Namibia. The second city, Livingstone in Zambia is a historic colonial city and tourism centre for Victoria Falls lying 10km south on the Zambezi River. Its airport has connections to Lusaka and Johannesburg in South Africa.
Mosi-oa-Tunya National Park in Zambia is an UNESCO World Heritage site along is twinned to the Victoria Falls National Park in Zimbabwe. It covers 66km2 from below the falls in a north-west arc along about 20km of the Zambian river bank.
The Devil´s Swimming Pool is a famous feature naturally formed, near the edge of the falls, accessed via Livingstone Island. People can swim as close as possible to the edge of the falls without continuing over the edge and falling into the gorge due to a natural rock wall that stops their progress despite the current.
