3.3BILLION YEARS AGO
Earth didnt stay as a water world very long.
Soon , the very first continents emerged from the ancient oceans.
Scientits call them cratons.
As more and more land rose from the ocean,the very firt supercontinent appeared on the planet.
Vaalbara wasnt exactly a supercontinent.
It was pretty small.
Scientits think it was smaller than the continent of Asutralia.
