Study Notes
Pangaea Formation
- The supercontinent Pangaea formed during the Paleozoic era, specifically in the Permian period, roughly 335 to 250 million years ago.
- The single ocean that surrounded Pangaea was called Panthalassa.
Continental Drift & Pangaea's Breakup
- Alfred Wegener proposed the theory of continental drift in 1912.
- The breaking up of Pangaea was caused by the forces of plate tectonics, specifically the movement of Earth's tectonic plates.
- The collision of Europe and Asia during Pangaea's formation created the Ural Mountains.
Evidence of Pangaea
- Before Wegener's theory, the prevailing explanation for similar fossils on different continents was that land bridges had once connected them.
- Evidence supporting the existence of Pangaea includes:
- Matching rock strata patterns on different continents.
- The distribution of fossil species across various continents.
- The discovery of tropical plant fossils in Antarctica, implying a different climate for the continent in the past.
- The distribution of fossil species across different continents suggests that the continents were once joined together.
- Matching rock strata patterns on different continents indicate a shared geological history.
- The discovery of tropical plant fossils in Antarctica suggests that the continent was once located in a warmer region.
Pangaea's Significance & Details
- The word Pangaea literally means “all Earth.”
- Gondwana, one of the two main parts of Pangaea, began to break apart approximately 180 million years ago.
- Wegener's observations of the apparent fit of the continents and the distribution of similar fossils across different continents led him to propose the existence of a supercontinent millions of years ago.
- The Tethys Sea formed between Laurasia and Gondwana, the two main parts of Pangaea.
- Pangaea broke apart approximately 200 million years ago due to the movement of tectonic plates.
