The geological history of the Earth follows the major geological events in Earth's past based on the geological time scale, a system of chronological measurement based on the study of the planet's rock layers (stratigraphy). Earth formed about 4.54 billion years ago by accretion from the solar nebula, a disk-shaped mass of dust and gas left ...
The name "Pangaea" is derived from Ancient Greek pan (πᾶν, "all, entire, whole") and Gaia or Gaea (Γαῖα, " Mother Earth, land"). [4][9] The first to suggest that the continents were once joined and later separated may have been Abraham Ortelius in 1596. [10] The concept that the continents once formed a contiguous land mass was ...
Earth formed in this manner about 4.54 billion years ago (with an uncertainty of 1%) [25] [26] [4] and was largely completed within 10–20 million years. [27] In June 2023, scientists reported evidence that the planet Earth may have formed in just three million years, much faster than the 10−100 million years thought earlier.
8 December 2019. (2019-12-08) Seven Worlds, One Planet is a television documentary series from the BBC Natural History Unit. The seven-part series, in which each episode focuses on one continent, debuted on 27 October 2019 and is narrated and presented by naturalist Sir David Attenborough. [1][2][3] Over 1,500 people worked on the series, which ...
The geologic time scale is a way of representing deep time based on events that have occurred throughout Earth's history, a time span of about 4.54 ± 0.05 Ga (4.54 billion years). [5] It chronologically organises strata, and subsequently time, by observing fundamental changes in stratigraphy that correspond to major geological or ...
The simulation lets us see that some continents split up more dramatically than others, including North America and Africa, which started coming apart pretty rapidly some 200 million years ago and ...
Carboniferous. The Carboniferous (/ ˌkɑːrbəˈnɪfərəs / KAR-bə-NIF-ər-əs) [6] is a geologic period and system of the Paleozoic that spans 60 million years from the end of the Devonian Period 358.9 Ma (million years ago) to the beginning of the Permian Period, 298.9 Ma. In North America, the Carboniferous is often treated as two ...
The Paleocene (IPA: / ˈpæli.əsiːn, - i.oʊ -, ˈpeɪli -/ PAL-ee-ə-seen, -ee-oh-, PAY-lee-), [4] or Palaeocene, is a geological epoch that lasted from about 66 to 56 million years ago (mya). It is the first epoch of the Paleogene Period in the modern Cenozoic Era. The name is a combination of the Ancient Greek παλαιός palaiós ...
