Study Notes
Formation of Continents
- The Gondwana Supercontinent, including Baltica, Siberia, and Laurasia, 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.Â
- These collisions resulted in the pre-Pangaea continent during the early Devonian period (390 Ma).
- The North American continent formed by the late Carboniferous (306 Ma).
- By the Triassic Period (255-210 Ma), Pangaea existed.
- Pangaea began to break apart from 210-180 Ma.
- The breakup of Pangaea continued into the Late Cretaceous period, creating larger oceans.
- Continental drift proceeded into the Tertiary Period.
- Continents reached their current positions during the Quaternary period.
Pangaea's Break-Up
- The present-day continents were part of the supercontinent Pangaea, existing until approximately 200 Ma.
- Around 160 Ma, Pangaea split into two large landmasses: Gondwanaland and Laurasia.Â
- The subcontinent of India moved northward and separated from Gondwana around 140 Ma.
- India collided with Eurasia, initiating the formation of the Himalayan mountain range.
- Australia separated from Antarctica around 100 Ma, further breaking Gondwana apart.
- The separation of Gondwana and Laurasia led to the opening of the Atlantic Ocean.
