Study Notes
Supercontinent Formation
- Gondwana Supercontinent existed around the South Pole during the late Cambrian period (514 Ma)
- During the mid-Ordovician Period (458 Ma), Laurasia collided with Baltica, closing the Iapetus Sea
- The continuous collisions in the early Devonian period (390 Ma) resulted in the pre-Pangaea continent
- North America formed by the late Carboniferous period (306 Ma), and Pangaea formed by the Triassic period (255-210 Ma)
Pangaea Breakup
- Pangaea began to break up from 210-180 Ma, a process that continued into the Late Cretaceous period, creating larger oceans
- Continental drift continued into the Tertiary Period, and continents reached their current positions during the Quaternary period.
- Pangaea split into two large landmasses: Gondwanaland and Laurasia, around 160 Ma
- The subcontinent of India moved northward and separated from Gondwana around 140 Ma, initiating the formation of the Himalayan mountain range
- Australia separated from Antarctica around 100 Ma, further breaking apart Gondwana.
- The separation of Gondwana and Laurasia led to the opening of the Atlantic Ocean
