Tales of Iguazu Falls and Other Wonders Quiz

Answer: Iguazu Falls

The largest waterfall system in the world, Iguazu Falls is located on the Iguazu River; while the river is located mostly in Brazil, the falls are found on the Argentina side of the border. About 257 separate falls, averaging 64 meters (210 feet) in height have been counted along 2.7 kilometers (1.67 miles) of the river. Measuring 82 meters (269 feet) high, 150 meters (492 feet) wide and 700 meters (2297 feet) long, the Garganta del Diablo, or Devil's Throat, is considered to be one of the most impressive waterfalls in Iguazu Falls National Park.

Answer: Hạ Long Bay

Located in northern Vietnam, Ha Long Bay extends approximately 120 kilometers (75 miles) long and contains 1,969 islands. Many of the islands are covered with limestone karsts, rock formations that feature sinkholes and caves, that are believed to have been formed over 20 million years, as well as thick jungle vegetation.

While many of the islands are uninhabited, they still provide tourists with beautiful beaches; some of the islands, however, have been inhabited for thousands of years.

Answer: Jeju Island

The largest island in South Korea, Jeju Island contains Hallasan, a dormant shield volcano and the highest mountain in South Korea. Although Hallasan was formed about 2 million years ago, the area remained unsettled until the 21st century because the land was difficult to cultivate. Because of this, the island also contains a nearly untouched area called the Gotjawal Forest. Visitors to the island may also see the Manjanggul lava tube; now a cave that once was a conduit for the flow of magma, the lava tube measures 8,928 meters (over 5.5 miles) long, and its passages are up to 30 meters (98 feet) high and 23 meters (75 feet) wide.

Answer: Puerto Princesa Underground River National Park

Filled with limestone karst formations, the Puerto Princesa Underground River National Park contains the underground part of the Cabayagan River system. It features the St. Paul Underground River Cave, which is about 24 kilometers (15 miles) long. The cave is comprised of several rooms; the Italian Chamber is believed to be one of the largest known cave rooms in the world.

After flowing underground, the river makes its way to the West Philippine Sea, which is an arm of the South China Sea. An unusual area due to its karsts and caves, as well as its forests, Puerto Princesa Underground River National Park contains a wide diversity of plants and animals.

Answer: Table Mountain

Over millions of years Table Mountain has maintained its form - a level plateau that eventually overlooked the city of Cape Town in South Africa. It is part of the Cape Fold Mountains, approximately 50 kilometers (31 miles) long, 6-10 kilometers (4-6 miles) wide, that stretches from the Cape of Good Hope to Table Mountain, which is the highest peak in the range.

The Table Mountain National Park is home to different species of fynbos, plants that make up a shrubland, and dassies, small mammals also known as rock hyraxes.

Answer: Komodo Island

Home of the largest living lizard on earth today, Komodo Island National Park includes the large islands of Komodo, Rinca, and Padar, along with some smaller ones. The park was formed in order to protect the famous Komodo dragons, as well as other species of plants and animals. Komodo Island also contains the famous Pink Beach that can only be reached by boat; on Pulau Kalong Island visitors can view a nightly bat migration. And the landscapes? They are spectacular! Interestingly, these incredible sights were not discovered until the early 20th century.

Answer: Amazon Rainforest

Coming in at Number 1 on the list of the New7Wonders of Nature, the Amazon Rainforest and River not only hold the distinction of forming the largest basin in the world, but the river also carries the highest volume of water. Covering 7,000,000 square kilometers (2,700,000 square miles), about 78% of the basin is covered by a rainforest, which is located in nine South American countries. Home to an estimated 390 billion trees, the area is considered to be the world's largest gathering of both plants and animals.

Answer: Grand Canyon

While the Grand Canyon made the Seven Natural Wonders of the World that was compiled by CNN, it is a runner-up to the list of the New7Wonders of Nature. The Grand Canyon, 446 kilometers (277 miles) long, up to 29 kilometers (18 miles) wide and 1857 kilometers (6,093 feet) deep, was carved by the Colorado River over 5 million years, and is over 277 river miles long.

While it is not the deepest canyon in the world - the Yarlung Tsangpo Grand Canyon in Tibet is - it contains a landscape unparalleled in beauty.

The area of the Grand Canyon National Park has been inhabited for thousands of years and held sacred by many groups of Native Americans.

Answer: Dead Sea

Another runner-up on the New7Wonders of Nature list, the Dead Sea is not only the world's lowest land elevation, but also, at 50 kilometers (31 miles) long and 15 kilometers (9 miles) wide at its widest point, the deepest hypersaline lake in the world. Estimated to be 9.6 times saltier than the oceans, the Dead Sea is not, however, considered to be the largest salty place on earth - Salar de Uyuni in Bolivia holds that distinction. Nevertheless, the Dead Sea has attracted visitors for thousands of years.

The Biblical town of Jericho was located nearby, as were Sodom and Gomorra. Some ancient people even collected the asphalt that still collects on the top of the Dead Sea; the ancient Egyptians, for example, were frequent travelers in the area and used the asphalt during mummification.

Answer: Great Barrier Reef

The Great Barrier Reef, off the coast of Queensland, Australia, is not only the largest coral reef in the world, but it is also the largest living thing in the world. Stretching over 2575 kilometers (1600 miles), the reef can be viewed from outer space! It is the home of billions of coral polyps, organisms that are related to jellyfish and sea anemones.

These soft-bodied creatures form a protective limestone skeleton at their base; these skeletons are the basis for the formation of the reef. The Great Barrier Reef is also home to dolphins, sea turtles, sea snakes, and frogs, as well as a variety of other animals.
