- Southeast Europe (Wikipedia)
Southeast Europe or Southeastern Europe (SEE) is a geographical sub-region of Europe, consisting primarily of the cultural region of the Balkans, as well as adjacent regions and archipelagos. There are overlapping and conflicting definitions of the region, due to political, economic, historical, cultural, and geographical considerations.
- Pangaea (Wikipedia)
Pangaea or Pangea (/pænˈdʒiː.ə/) was a supercontinent that existed during the late Paleozoic and early Mesozoic eras. It assembled from the earlier continental units of Gondwana, Euramerica and Siberia during the Carboniferous approximately 335 million years ago, and began to break apart about 200 million years ago, at the end of the Triassic and beginning of the Jurassic. In contrast to the present Earth and its distribution of continental mass, Pangaea was centred on the equator and surrounded by the superocean Panthalassa and the Paleo-Tethys and subsequent Tethys Oceans. Pangaea is the most recent supercontinent to have existed and the first to be reconstructed by geologists.
