Seven Natural Wonders Of World

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. Following is the One of the many lists that was compiled by CNN.

1. Grand Canyon

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 conservation of the Grand Canyon area, and visited on numerous occasions to hunt and enjoy the scenery.

The canyon, created by the Colorado River over about 6 million years, is 277 miles (446 km) long, ranges in width from 4 to 18 miles (6.4 to 24 kilometers), and attains a depth of more than a mile (1.6 km). Nearly two billion years of the Earth's history have been exposed as the Colorado River and its tributaries cut their channels through layer after layer of rock while the Colorado Plateau was uplifted.


2. Great Barrier Reef

The Great Barrier Reef in Australia 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 square kilometres (132,974 sq mi). The reef is located in the Coral Sea, off the coast of Queensland in northeast 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.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.

3. Harbor of Rio de Janeiro

Rio de Janeiro , ("River of January" in English) is a major city in southeastern Brazil and the capital of the state of Rio de Janeiro. The city was once 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 and Ipanema, paved with decorated black and cream swirl pattern mosaics, and also for its huge social disparities, shanty towns, violence and drug traffic. Some of the most famous local landmarks in addition to the beaches include the giant statue of Jesus, known as Christ the Redeemer atop Corcovado mountain; Sugarloaf mountain (Pão de Açúcar) with its cable car; the Sambódromo, a giant permanent parade stand used during Carnival; and Maracanã stadium, one of the world's largest football stadiums. Rio also boasts the world's largest forest inside an urban area, called Floresta da Tijuca, or 'Tijuca Forest'.

4. Mount Everest

Mount Everest or Qomolangma or Sagarmatha is the highest mountain on Earth, as measured by the height of its summit above sea level. The mountain, which is part of the Himalaya range in High Asia, is located on the border between Nepal and Tibet, China. As of the end of the 2006 climbing season, there have been 3,050 ascents to the summit, by 2,062 individuals, and 203 people have died on the mountain. The conditions on the mountain are so difficult that most of the corpses have been left where they fell; some of them are easily visible from the standard climbing routes.

Climbers are a significant source of tourist revenue for Nepal; they range from experienced mountaineers to relative novices who count on their paid guides to get them to the top. The Nepalese government also requires a permit from all prospective climbers; this carries a heavy fee, often more than $25,000 (USD) per person.

5. Polar Aurora

An aurora (plural aurorae/auroras) is an electro-static phenomenon, characterised by a bright glow and caused by the collision of charged particles in the magnetosphere with atoms in the Earth's upper atmosphere. An aurora is usually observed in the night sky, particularly in the polar zone. For this latter reason, some scientists call it a "polar aurora" (or "aurora polaris"). In northern latitudes, it is known as the aurora borealis , which is named after the Roman goddess of the dawn, Aurora, and the Greek name for north wind, Boreas. Especially in Europe, it often appears as a reddish glow on the northern horizon, as if the sun were rising from an unusual direction. The aurora borealis is also called the northern lights since it is only visible in the North sky from the Northern Hemisphere. The aurora borealis most often occurs from September to October and from March to April. Its southern counterpart, aurora australis, has similar properties. Australis is the Latin word for "of the South".

6. Parícutin volcano


Parícutin is a volcano in the Mexican state of Michoacán, close to a lava-covered village of the same name. It appears on many versions of the Seven Natural Wonders of the World.

It began as a fissure in a cornfield owned by Tarascan farmer Dionisio Pulido on February 20, 1943. Pulido, his wife, and son, all witnessed the initial eruption of ash and stones first-hand as they plowed the field. Much of the volcano's growth occurred during its first year, while it was still in the explosive pyroclastic phase. Nearby villages Paricutín (after which the volcano was named) and San Juan Parangaricutiro were both buried in lava and ash; the residents relocated to vacant land nearby.

7. Victoria Falls

Africa's Victoria Falls or Mosi-oa-Tunya (the Smoke that Thunders) are, by some measures, the largest waterfall in the world, as well as being among the most unusual in form, and having arguably the most diverse and easily-seen wildlife of any major waterfall site.

The unusual form of Victoria Falls enables virtually the whole width of the falls to be viewed face-on, at the same level as the top, from as close as 60 m (200 ft), because the whole Zambezi River drops into a deep, narrow slot-like chasm, connected to a long series of gorges. Few other waterfalls allow such a close approach on foot

Many of Africa's animals and birds can be seen in the immediate vicinity of Victoria Falls, and the continent's range of river fish is also well represented in the Zambezi, enabling wildlife viewing and sport fishing to be combined with sightseeing.
The falls are shared between Zambia and Zimbabwe, and each country has a national park to protect them and a town serving as a tourism centre: Mosi-oa-Tunya National Park and Livingstone in Zambia, and Victoria Falls National Park and the town of Victoria Falls in Zimbabwe.

These truly are amazing - I have seen Victoria Falls, the Grand Canyon and the Northern Lights.

There is a global effort to protect and promote the 7 natural wonders - you can add your name to the Protection Petition at http://sevennaturalwonders.org
