An image of Afro-Eurasia, the largest landmass on Earth. A landmass, or land mass, is a large region or area of land that is in one piece and not noticeably broken up by oceans. [1] [2] The term is often used to refer to lands surrounded by an ocean or sea, such as a continent or a large island. [3] [4] In the field of geology, a landmass is a ...
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 ...
A continent is any of several large geographical regions. Continents are generally identified by convention rather than any strict criteria. A continent could be a single large landmass, a part of a very large landmass, as in the case of Asia or Europe within Eurasia, or a landmass and nearby islands within its continental shelf. Due to these ...
A continent is a large geographical region defined by the continental shelves and the cultures on the continent. [1] In the modern day, there are seven continents. However, there have been more continents throughout history. Vaalbara was the first supercontinent. [2] Europe is the newest continent. [3]
According to modern definitions, a supercontinent does not exist today; [1] the closest is the current Afro-Eurasian landmass, which covers approximately 57% of Earth's total land area. The last period in which the continental landmasses were near to one another was 336 to 175 million years ago, forming the supercontinent Pangaea .
It covers roughly 539 million years. During this period continents drifted apart, but eventually collected into a single landmass known as Pangea, before splitting again into the current continental landmasses. [citation needed] The Phanerozoic is divided into three eras – the Paleozoic, the Mesozoic and the Cenozoic.
Map of Pangea around 250 million years ago, at the beginning of the Triassic. Pangaea or Pangea (/ p æ n ˈ dʒ iː ə / pan-JEE-ə) [1] was a supercontinent that existed during the late Paleozoic and early Mesozoic eras. [2]
Eurasia (/ j ʊəˈr eɪ ʒ ə / yoor-AY-zhə, also UK: /-ʃ ə /-shə) is the largest continental area on Earth, comprising all of Europe and Asia. [3] [4] According to some geographers, physiographically, Eurasia is a single supercontinent. [4]
