Natural wonders

Similar to the other lists of wonders, there is no consensus on a list of seven natural wonders of the world, as there has been debate over how large the list should be. One of the many lists was compiled by CNN:
Grand Canyon
Great Barrier Reef
Harbor of Rio de Janeiro
Mount Everest
Polar Aurora
Parнcutin volcano
Victoria Falls
The Grand Canyon is a very colorful, steep-sided gorge, carved by the Colorado River, in the U.S. state of Arizona. It is largely contained within the Grand Canyon National Park — one of the first national parks in the United States. President Theodore Roosevelt was a major proponent of the Grand Canyon area, visiting on numerous occasions to hunt and enjoy the scenery.
The canyon, created by the Colorado River cutting a channel over millions of years, is about 277 miles (446 km) long, ranges in width from 0.25 to 15 miles (0.4 to 24 kilometers), and attains a depth of more than a mile (1 km). Nearly two billion years of the Earth's history has been exposed as the Colorado River and its tributaries cut through layer after layer of sediment as the Colorado Plateaus have uplifted.
The first recorded sighting of the Grand Canyon by a European was in 1540, Garcнa Lуpez de Cбrdenas from Spain. Grand Canyon was largely unknown until after the U.S. Civil War. In 1869, Major John Wesley Powell, a one-armed Civil War veteran with a thirst for science and adventure, made a pioneering journey through the canyon on the Colorado River. He accomplished this with nine men in four small wooden boats, though only six men completed the journey. His party was, as far as we know, the first ever to make such a trip. Powell referred to the sedimentary rock units exposed in the canyon as "leaves in a great story book". Long before that, the area was inhabited by Native Americans who built settlements within the canyon walls and its many caves.
The Great Barrier Reef is the world's largest coral reef system, composed of roughly 3,000 individual reefs and 900 islands that stretch for 2,600 kilometres (1,616 mi) and cover an area of approximately 344,400 kmІ. The reef is located in the Coral Sea, off the coast of Queensland in northeast Australia. A large part of the reef is protected by the Great Barrier Reef Marine Park.
The Great Barrier Reef can be seen from outer space and is sometimes referred to as the single largest organism in the world. In reality, it is made up of many millions of tiny organisms, known as coral polyps. The Great Barrier Reef supports a wide diversity of life and was selected as a World Heritage Site in 1981.CNN has labelled it one of the seven natural wonders of the world. The Queensland National Trust has named it a state icon of Queensland.
The Great Barrier Reef's environmental pressures include water quality from runoff, climate change and mass coral bleaching, cyclic outbreaks of the crown-of-thorns starfish, overfishing, and shipping accidents.
Rio de Janeiro (IPA: Portuguese: "River of January"; is the name of both a state and a city in southeastern Brazil. The city was the capital of Brazil (1763–1960) and of the Portuguese Empire (1808–1821). Commonly known as just Rio, the city is also nicknamed A Cidade Maravilhosa - "The Marvelous City".
It is famous for its spectacular natural setting, its Carnival celebrations, samba and other music, hotel-lined tourist beaches, such as Copacabana, Ipanema, and Leblon and pavements decorated with black and cream swirl pattern mosaics. Some of the most famous local landmarks in addition to the beaches include the giant statue of Jesus, known as Christ the Redeemer ('Cristo Redentor') atop Corcovado mountain; Sugarloaf mountain (Pгo de Aзъcar) with its cable car; the Sambуdromo, a giant permanent parade stand used during Carnival; and Maracanг stadium, the world's largest. Rio also boasts the world's largest forest inside an urban area, called Floresta da Tijuca, or 'Tijuca Forest'.
Rio de Janeiro is located at 22 degrees, 54 minutes south latitude, 43 degrees 14 minutes west longitude (22°54?S 43°14?W).
