The breakup of the supercontinent Pangea was a major event in Earth’s geological history. It led to the formation of the continents as we know them today and influenced the planet’s climate, ocean currents, and biological evolution.
The Formation of Pangea
Pangea was a supercontinent that existed during the late Paleozoic and early Mesozoic eras. It assembled from earlier landmasses through tectonic plate movements and was surrounded by a vast ocean called Panthalassa.
The Process of Breakup
The breakup of Pangea began around 175 million years ago during the Jurassic period. Tectonic forces caused the supercontinent to rift apart, gradually forming separate landmasses that drifted to their current positions.
This process was driven by mantle convection, which caused the Earth’s plates to move. As a result, continents separated and moved toward their present-day locations over millions of years.
Impact on Earth’s Environment
The breakup of Pangea significantly affected Earth’s climate and ocean circulation. The separation created new coastlines and ocean basins, influencing weather patterns and marine life distribution.
