单词 Pangaea
释义
Pangaea

Geology and Earth Sciences
  • A single supercontinent which came into being in late Permian times and persisted for about 40 million years before it began to break up at the end of the Triassic period; or, in the view of some people, which existed throughout most of the Earth’s history prior to the Triassic. It was surrounded by the universal ocean of Panthalassa.


Geography
  • A supercontinent comprising all of Earth’s landmass, before it was split by continental drift. Crowley et al. (1989) Geology 17, 5 find that very high summer temperatures and a large annual range are major features of supercontinents; a finding with implications for Permian extinctions.

    See W. M. Marsh and M. M. Kaufman (2012), p. 246 on the movements of India during the break-up of Pangaea.
