Victoria Falls. Naming David Livingstone gazing upon the Falls, in bronze, from the Zambian shore.
David Livingstone, the Scottish missionary and explorer, is believed to have been the first European to view Victoria Falls on 16 November 1855 from what is now known as Livingstone Island, one of two land masses in the middle of the river, immediately upstream from the falls on the Zambian side. Livingstone named his discovery in honour of Queen Victoria, but the indigenous name, Mosi-oa-Tunya—"the smoke that thunders"—continues in common usage as well. The nearby national park in Zambia, for example, is named Mosi-oa-Tunya, whereas the national park and town on the Zimbabwean shore are both named Victoria Falls. The World Heritage List officially recognizes both names.
Parícutin. Parícutin (or Volcán de Parícutin, also accented Paricutín) is a cinder cone volcano in the Mexican state of Michoacán, close to a lava-covered village of the same name.
The volcano is unique in the fact that its evolution from creation to extinction was witnessed, observed and studied. It appears on many versions of the Seven Natural Wonders of the World. Parícutin is part of the Michoacán–Guanajuato volcanic field, which covers much of west central Mexico. It is part of the Ring of Fire. History Three weeks before the actual eruption, rumbling noises that resembled thunder were heard by people near Parícutin village. Aurora (astronomy)
Images of the aurora australis and aurora borealis from around the world, including those with rarer red and blue lights Overview Auroras are classified as diffuse and discrete.
The diffuse aurora is a featureless glow in the sky that may not be visible to the naked eye, even on a dark night. It defines the extent of the auroral zone. The discrete auroras are sharply defined features within the diffuse aurora that vary in brightness from just barely visible to the naked eye, to bright enough to read a newspaper by at night. Its southern counterpart, the aurora australis (or the southern lights), has features that are almost identical to the aurora borealis and changes simultaneously with changes in the northern auroral zone. It is visible from high southern latitudes in Antarctica, South America, New Zealand, and Australia. History of aurora theories Multiple superstitions and obsolete theories explaining the aurora have surfaced over the centuries. Auroral mechanism Mount Everest. Everest from space Mount Everest (also known in Nepal as Sagarmatha and in Tibet as Chomolungma) is the Earth's highest mountain.
It is located in the Mahalangur section of the Himalayas. Its peak is 8,848 metres (29,029 ft) above sea level and is the 5th furthest point from the centre of the Earth. The international border between China and Nepal runs across the precise summit point. Its massif includes neighboring peaks Lhotse, 8,516 m (27,940 ft); Nuptse, 7,855 m (25,771 ft) and Changtse, 7,580 m (24,870 ft). In 1856, the Great Trigonometric Survey of India established the first published height of Everest, then known as Peak XV, at 29,002 ft (8,840 m). Mount Everest attracts many highly experienced mountaineers as well as capable climbers willing to hire professional guides. Discovery Location on Earth. Rio de Janeiro. Great Barrier Reef. The Great Barrier Reef is the world's largest coral reef system composed of over 2,900 individual reefs and 900 islands stretching for over 2,300 kilometres (1,400 mi) over an area of approximately 344,400 square kilometres (133,000 sq mi). The reef is located in the Coral Sea, off the coast of Queensland, Australia.
The Great Barrier Reef can be seen from outer space and is the world's biggest single structure made by living organisms. This reef structure is composed of and built by billions of tiny organisms, known as coral polyps. It supports a wide diversity of life and was selected as a World Heritage Site in 1981. CNN labeled it one of the seven natural wonders of the world. The Queensland National Trust named it a state icon of Queensland. Grand Canyon. View from the South Rim The Grand Canyon (Hopi: Ongtupqa; Yavapai: Wi:kaʼi:la) is a steep-sided canyon carved by the Colorado River in the United States in the state of Arizona.
It is contained within and managed by Grand Canyon National Park, the Hualapai Tribal Nation, and the Havasupai Tribe. President Theodore Roosevelt was a major proponent of preservation of the Grand Canyon area, and visited it on numerous occasions to hunt and enjoy the scenery. For thousands of years, the area has been continuously inhabited by Native Americans who built settlements within the canyon and its many caves. The Pueblo people considered the Grand Canyon ("Ongtupqa" in Hopi language) a holy site and made pilgrimages to it. The first European known to have viewed the Grand Canyon was García López de Cárdenas from Spain, who arrived in 1540. Geography
