Archean mobile crust –

smaller pieces moving more rapidly Between 2.7 and 2.3 billion years ago, most small crustal bodies collided to form larger cratons

Platform or continental platform

Platform phase – beginning with the Proterozoic Eon, characterized by relatively stable cratons

NGSS.MS-ESS2-2

a plate tectonic cycle in which most of the major continent pieces converge to make a supercontinent; diverge to create crust between them; and then converge again to make a new supercontinent- it takes about 100 -300 million years to cycle

• protero cycle or rodinia cycle

• Rock Cycle or tonic cycle

• Supercontinent cycle or Wilson Cycle
