how did a supercontinent form
In geology, a supercontinent is the assembly of most or all of the Earth 's continental blocks or cratons to form a single large landmass.However, the definition of a supercontinent can be ambiguous.angaea's supercontinent cycle is a good example for the efficiency of using the presence, or lack of, these entities to record the development, tenure, and break-up of supercontinents. There is a sharp decrease in passive margins between 500 and 350 Ma during the timing of Pangaea's assembly.
