[ad_1] 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 […]

A future supercontinent, Pangea Ultima, has been tentatively named. […]
