The supercontinent cycle sees the Earth’s continents merge and split every 300-500 million years due to tectonic plate movement. Previous supercontinents include Pangea and Gondwanaland, and the cycle affects Earth’s climate and coastlines. The supercontinent cycle is a geological cycle in which the Earth’s continents alternately merge into a single supercontinent, split into numerous continents, […]
Supercontinents are continents that include multiple cratons, with Pangea being an example that encompassed almost all land on Earth. Seafloor spreading causes continents to come together and form a supercontinent, which eventually splits again in a cycle that repeats every 250 to 500 million years. A future supercontinent, Pangea Ultima, has been tentatively named. Supercontinents […]
