Ural MountainsThe Ural Mountains (ˈjʊərəl ; Уральские горы) or simply the Urals, is a mountain range in Eurasia that runs north-south mostly through Russia, from the coast of the Arctic Ocean to the river Ural and northwestern Kazakhstan. The mountain range forms part of the conventional boundary between the continents of Europe and Asia. Vaygach Island and the islands of Novaya Zemlya form a further continuation of the chain to the north into the Arctic Ocean. The average altitudes of the Urals are around , the highest point being Mount Narodnaya, which reaches a height of .
World populationIn demographics, the world population is the total number of humans currently living. It was estimated by the United Nations to have exceeded eight billion in mid-November 2022. It took over 200,000 years of human prehistory and history for the human population to reach one billion and only 219 years more to reach 8 billion. The human population has experienced continuous growth following the Great Famine of 1315–1317 and the end of the Black Death in 1350, when it was nearly 370,000,000.
Caucasus MountainsThe Caucasus Mountains are a mountain range at the intersection of Asia and Europe. Stretching between the Black Sea and the Caspian Sea, they are surrounded by the Caucasus region and are home to Mount Elbrus, the highest peak in Europe at above sea level. The Caucasus Mountains include the Greater Caucasus in the north and Lesser Caucasus in the south. The Greater Caucasus runs west-northwest to east-southeast, from the Western Caucasus on the northeastern shore of the Black Sea to Baku on the Caspian Sea.
Javan rhinocerosThe Javan rhinoceros (Rhinoceros sondaicus), also known as the Javan rhino, Sunda rhinoceros or lesser one-horned rhinoceros, is a very rare member of the family Rhinocerotidae and one of five extant rhinoceroses. It belongs to the Rhinoceros genus and has a mosaic, armour-like skin, is long and high. Its horn is usually shorter than . Only adult bulls have horns. The Javan rhinoceros ranged from the islands of Java and Sumatra throughout Southeast Asia and into India and China.
Australia (continent)The continent of Australia, sometimes known in technical contexts by the names Sahul (səˈhuːl), Australia-New Guinea, Australinea, Meganesia, or Papualand to distinguish it from the country of Australia, is located within the Southern and Eastern hemispheres. The name "Sahul" takes its name from the Sahul Shelf, which is a part of the continental shelf of the Australian continent. The continent includes mainland Australia, Tasmania, the island of New Guinea (Papua New Guinea and Western New Guinea), the Aru Islands, the Ashmore and Cartier Islands, most of the Coral Sea Islands, and some other nearby islands.
IslandAn island or isle is a piece of subcontinental land completely surrounded by water. Very small islands such as emergent land features on atolls can be called islets, skerries, cays or keys. An island in a river or a lake island may be called an eyot or ait, and a small island off the coast may be called a holm. Sedimentary islands in the Ganges Delta are called chars. A grouping of geographically or geologically related islands, such as the Philippines, is referred to as an archipelago.
IbexAn ibex (: ibex, ibexes or ibices) is any of several species of wild goat (genus Capra), distinguished by the male's large recurved horns, which are transversely ridged in front. Ibex are found in Eurasia, North Africa and East Africa. The name ibex comes from Latin, borrowed from Iberian or Aquitanian, akin to Old Spanish bezerro "bull", modern Spanish becerro "yearling". Ranging in height from and weighing , ibex can live up to 20 years. Three closely related varieties of goats found in the wild are not usually called ibex: the markhor, western tur, and eastern tur.
Lena (river)The Lena (Ле́на, ˈljɛnə; Елюенэ, Eljune; Өлүөнэ, Ölüöne; Зүлхэ, Zülkhe; Зүлгэ, Zülge) is a river (En: Helen) in the Russian Far East, and is the easternmost of the three great Siberian rivers that flow into the Arctic Ocean (the other two being the Ob and the Yenisey). The Lena is the eleventh-longest river in the world, and the longest river entirely within Russia, with a length of and a drainage basin of . Permafrost underlies most of the catchment, 77% of which is continuous.
Land bridgeIn biogeography, a land bridge is an isthmus or wider land connection between otherwise separate areas, over which animals and plants are able to cross and colonize new lands. A land bridge can be created by marine regression, in which sea levels fall, exposing shallow, previously submerged sections of continental shelf; or when new land is created by plate tectonics; or occasionally when the sea floor rises due to post-glacial rebound after an ice age.
Indian subcontinentThe Indian subcontinent is a physiographical region in Southern Asia, situated on the Indian Plate, projecting southwards into the Indian Ocean from the Himalayas. Geopolitically, it spans major landmasses from the countries of Bangladesh, Bhutan, India, Maldives, Nepal, Pakistan, and Sri Lanka. Although the terms "Indian subcontinent" and "South Asia" are often used interchangeably to denote the region, the geopolitical term of South Asia frequently includes Afghanistan, which is not considered part of the subcontinent.
