The Great Dividing Range, also known as the Eastern Highlands, is Australia's most substantial mountain range, running along the entire eastern coast of the continent. It stretches for more than 3,500 kilometers (2,175 miles) from the tip of Queensland down through New South Wales and Victoria to the Grampians in South Australia. The range acts as a major drainage divide, separating the rivers that flow to the Pacific Ocean from those that flow inland toward the Murray-Darling Basin.

Reykjav?k, the capital of Iceland, is the most northerly capital city of a sovereign state in the world, located just south of the Arctic Circle. Despite its northern location, the city enjoys a relatively mild climate due to the warming effects of the Gulf Stream, and it is world-renowned for its colorful houses, creative arts scene, and reliance on geothermal energy.

The Arctic Tern holds the record for the longest migration of any animal in the world, traveling from its breeding grounds in the Arctic to the Antarctic and back every year. This incredible journey can cover over 70,000 kilometers (43,000 miles) annually, ensuring that the bird sees two summers and more daylight than any other creature. Because of this lifestyle, a single Arctic Tern may travel the equivalent of three round trips to the Moon over its 30-year lifespan.

Dutch is the official language of Suriname, a small country on the northeastern coast of South America that was formerly a colony of the Netherlands. It is the only country outside of Europe where Dutch is spoken by a majority of the population as a first or second language.

Victoria Falls, one of the world's largest and most famous waterfalls, is located on the Zambezi River on the border between Zambia and Zimbabwe in southern Africa. Known locally as Mosi-oa-Tunya or "The Smoke That Thunders," the falls create a massive curtain of falling water that drops into a deep gorge, sending mist high into the air that can be seen from miles away.

The Salar de Uyuni in Bolivia is the world's largest salt flat, covering over 10,000 square kilometers of the high Altiplano plateau. It was formed by the evaporation of ancient prehistoric lakes, leaving behind a thick crust of salt that contains more than half of the world's known lithium reserves. When a thin layer of water covers the salt flat during the rainy season, it becomes a giant mirror that perfectly reflects the sky.

The Okapi is a strange-looking animal native to the dense rainforests of the Democratic Republic of the Congo. Although it has zebra-like stripes on its legs for camouflage, it is actually the only living relative of the Giraffe. Like giraffes, okapis have long, blue, prehensile tongues that they use to strip leaves from trees and even to clean their own ears.

The Volga River, flowing entirely through Russia, is the longest river in Europe and is widely regarded as the national river of the country. It flows for approximately 3,530 kilometers (2,193 miles) into the Caspian Sea and is a vital waterway for transport, irrigation, and the generation of hydroelectric power.

The Congo River in Central Africa is the primary setting for Joseph Conrad's famous 1899 novella, 'Heart of Darkness'. In the book, the river serves as a powerful symbol of the journey into the unknown and the dark side of European colonialism in Africa. The river itself is the second-longest in Africa and the deepest river in the world, with some points reaching over 220 meters (720 feet) deep.

The Caucasus Mountains are a major mountain range located between the Black Sea and the Caspian Sea, forming part of the traditional boundary between Europe and Asia. This rugged region is home to Mount Elbrus, the highest peak in Europe, and is famous for its incredible ethnic, linguistic, and cultural diversity.

The Resplendent Quetzal is a brilliantly colored bird that is the national symbol of Guatemala and gives its name to the country's official currency. It is famous for its vibrant green plumage and the incredibly long tail feathers of the male, which can grow up to three feet in length during the breeding season. In ancient Maya and Aztec cultures, the bird was considered sacred, and its feathers were used to create magnificent royal headdresses.

The Seychelles is a beautiful archipelago of 115 islands in the Indian Ocean and is officially the smallest country in Africa by both land area and population. It is world-renowned for its pristine white-sand beaches, crystal-clear turquoise waters, and unique granite rock formations. The nation is a leader in environmental conservation, with nearly half of its total land area protected in nature reserves.

Bhutan is famously known as the "Land of the Thunder Dragon" (Druk Yul) because of the violent storms that frequently roll down from the Himalayas. This name is reflected in the country's national identity, with a white dragon appearing on the national flag and the people themselves being called the Drukpa.

The Tian Shan mountains, which means "Celestial Mountains" in Chinese, are a large system of mountain ranges located primarily in the border region of China, Kazakhstan, Kyrgyzstan, and Uzbekistan. They form part of the great Himalayan mountain belt and contain some of the highest peaks in the world outside of the Himalayas and Karakoram. The range is a UNESCO World Heritage site and has historically been a major corridor for the Silk Road.

Lake Malawi, also known as Lake Nyasa, is famous for having the highest number of fish species of any lake in the world, particularly its diverse population of cichlids. These colorful fish have undergone rapid evolution, with hundreds of unique species found only within this single lake. The lake is the southernmost of the East African Rift lakes and is shared by Malawi, Mozambique, and Tanzania.

Antarctica is the only continent on Earth that has no native species of ants, likely due to the extreme cold and the lack of permanent vegetation and soil. While ants are found in almost every other terrestrial habitat on the planet, from tropical rainforests to deserts, they cannot survive the frozen landscape of the South Pole. There are also no native ants on some remote islands like Greenland and parts of Iceland.

China is the world's top exporter and producer of tea, a tradition that dates back thousands of years to ancient Chinese dynasties.

Lake Vostok is the largest of Antarctica's nearly 400 known subglacial lakes, located beneath the East Antarctic Ice Sheet. It is buried under approximately 3.7 kilometers 2.3 miles of ice and has been isolated from the atmosphere for millions of years. Scientists are extremely interested in the lake because it may contain unique microbial life forms that have evolved in total darkness and extreme pressure.

The Bongo is a rare and striking forest antelope characterized by its deep reddish-brown coat and bright white vertical stripes. It is native to the dense tropical jungles of Central and West Africa, specifically the Congo Basin and the mountains of Kenya. These animals are extremely shy and nocturnal, making them one of the most difficult large mammals to spot in the wild.

Africa is the only continent in the world through which the Equator, the Tropic of Cancer, and the Tropic of Capricorn all pass, making it the most centrally located continent relative to the Earth's latitudes. This unique positioning means that the vast majority of the continent lies within the tropical zone, resulting in a wide variety of ecosystems ranging from the Sahara Desert to the lush Congo Rainforest.
