the earth's continents started to form in the archean, although details about their formation are still being debated, due to lack of extensive geological evidence. one hypothesis is that rocks that are now in india, western australia, and southern africa formed a continent called ur as of 3,100 ma. a differing conflicting hypothesis is that rocks from western australia and southern africa were assembled in a continent called vaalbara as far back as 3,600 ma. although the first continents formed during this eon, rock of this age makes up only 7% of the present world's cratons; even allowing for erosion and destruction of past formations, evidence suggests that only 5–40% of the present area of continents formed during the archean.
