Gondwana (/ ɡ ɒ n d ˈ w ɑː n ə /) [1] was a large landmass, sometimes referred to as a supercontinent.The remnants of Gondwana make up around two-thirds of today's continental area, including South America, Africa, Antarctica, Australia, Zealandia, Arabia, and the Indian Subcontinent.
The southern continents remained tied together in the supercontinent Gondwana, which collided with North America-Europe along the present line of eastern North America. This continental collision resulted in the Hercynian orogeny in Europe, and the Alleghenian orogeny in North America; it also extended the newly uplifted Appalachians ...
c. 4,450 Ma – 100 million years after the Moon formed, the first lunar crust, formed of lunar anorthosite, differentiates from lower magmas. The earliest Earth crust probably forms similarly out of similar material. On Earth the pluvial period starts, in which the Earth's crust cools enough to let oceans form.
Laurentia, the Palaeozoic core of North America and continental fragments that now make up part of Europe, collided with Baltica and Avalonia in the Caledonian orogeny c. 430–420 Mya to form Laurussia. In the Late Carboniferous Laurussia and Gondwana formed Pangaea.
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.
Gondwana is a former supercontinent that broke off from the landmass of Pangea about 180 million years ago. It included South America, Africa, Australia and Antarctica.
The Mozambique Belt, extending from east Antarctica through East Africa up to the Arabian-Nubian Shield, formed as a suture between plates during the Pan-African orogeny. [8] The Mozambique ocean began closing between Madagascar-India and the Congo – Tanzania craton between 700 and 580 million years ago, with closure between 600 and 500 ...
