A supercontinent is an extensive landmass that dominates the Earth’s land. It is formed by amalgamating all or most of the Earth’s continental blocks or cratons into a single vast mass.
Some geologists employ a different definition that characterizes it as a collection of previously dispersed continents, which is simpler to apply to Precambrian periods and allows for diverse interpretations.
The customary definition of a supercontinent is that it encompasses approximately 75% of the extant continental crust, making it a remarkable geological phenomenon.
