Australia, officially the Commonwealth of Australia,[17] is a country comprising the mainland of the Australian continent, the island of Tasmania and numerous smaller islands.[18] Australia has a total area of 7,688,287 km2 (2,968,464 sq mi), making it the sixth-largest country in the world and the largest in Oceania. It is the world's oldest,[19] flattest,[20] and driest inhabited continent,[21][22] with some of the least fertile soils.[23][24] It is a megadiverse country, and its size gives it a wide variety of landscapes and climates including deserts in the interior and tropical rainforests along the coast

The Americas, sometimes collectively called America,[3][4][5] initially called India Nova by Europeans,[6] are a landmass comprising the totality of North America and South America.[6][7][8] When viewed as a single continent, the Americas or America is the 2nd largest continent right after Asia, and is the 3rd largest continent by population. The Americas make up most of the land in Earth's Western Hemisphere and comprise the New World

Europe is a continent[t] located entirely in the Northern Hemisphere and mostly in the Eastern Hemisphere. It is bordered by the Arctic Ocean to the north, the Atlantic Ocean to the west, the Mediterranean Sea to the south, and Asia to the east. Europe shares the landmass of Eurasia with Asia, and of Afro-Eurasia with both Africa and Asia.[9][10] Europe is commonly considered to be separated from Asia by the watershed of the Ural Mountains, the Ural River, the Caspian Sea, the Greater Caucasus, the Black Sea, and the waterway of the Bosporus Strait

Africa is the world's second-largest and second-most populous continent after Asia. At about 30.3 million km2 (11.7 million square miles) including adjacent islands, it covers 20% of Earth's land area and 6% of its total surface area.[9] With nearly 1.4 billion people as of 2021, it accounts for about 18% of the world's human population. Africa's population is the youngest among all the continents;[10][11] the median age in 2012 was 19.7, when the worldwide median age was 30.4.[12] Based on 2024 projections, Africa's population will reach 3.8 billion people by 2099.[13] Africa is the least wealthy inhabited continent per capita and second-least wealthy by total wealth, ahead of Oceania. Scholars have attributed this to different factors including geography, climate,[14] corruption,[14] colonialism, the Cold War,[15][16] and neocolonialism. Despite this low concentration of wealth, recent economic expansion and a large and young population make Africa an important economic market in the broader global context. Africa has a large quantity of natural resources and food resources, including diamonds, sugar, salt, gold, iron, cobalt, uranium, copper, bauxite, silver, petroleum, natural gas, cocoa beans, and tropical fruit.

Asia (/ˈeɪʒə/ AY-zhə, UK also /ˈeɪʃə/ AY-shə) is the largest continent[note 1][10][11] in the world by both land area and population.[11] It covers an area of more than 44 million square kilometres,[note 2] about 30% of Earth's total land area and 8% of Earth's total surface area. The continent, which has long been home to the majority of the human population,[12] was the site of many of the first civilisations. Its 4.7 billion people constitute roughly 60% of the world's population.
