The major geological event of the Cambrian Period is that Rodina, the land mass that included all of the continents on Earth, split apart to form separate land masses that would eventually become the Earth as we know it today. The Cambrian Period lasted for about 53 million years.
When the Cambrian Period began, land on Earth consisted of one super-continent called the Rodina. By the middle of the period, the Rodina broke apart into two different continents.
The mass that would eventually become modern Africa, Australia, South America, Antarctica and parts of Asia was called Gondwana, and it was located near the South Pole.
Laurentia would break up to become North America and much of Europe and it was located closer to the equator.
