Human timeline and Nature timeline An artist's impression of Pannotia, about million years ago, in the Ediacaran period.
Piper was probably the first to propose a Proterozoic supercontinent preceding Pangaea, today known as Rodinia. This term recognizes that the supercontinent of Gondwana, which formed at the end of the Neoproterozoic, was once part of the much larger end-Neoproterozoic supercontinent.
Lawrence Iroquoian word from which the name 'Canada' is derived, while keeping the name Rodinia for the latter Neoproterozoic supercontinent now known as Pannotia. Rodinia Ma, view centred on the Equator. Reconstruction from Goodge et al.
Less certain position of continental blocks includes: The peak in this mountain building event was around — Ma, but these continental collisions may have continued into the Early Cambrian some Ma. The formation of Pannotia was the result of Rodinia turning itself inside out.
Laurentia, which 'escaped' out of Rodinia, Baltica, and Siberia, kept the relative positions they had in Rodinia. The Cathaysian and Cimmerian terranes continental blocks of southern Asia were located along the northern margins of east Gondwana.
This orogeny probably extended north into the Uralian margin of Baltica. The material that was accreted included — Ma mafic meta-igneous complexes and younger arc-related rocks.
This opening of the Iapetus and other Cambrian seas coincided with the first steps in the evolution of soft-bodied metazoans, and also made a myriad of habitats available for them; this led to the so-called Cambrian explosion, the rapid evolution of skeletalized metazoans.This animation shows the motions of the continents into the future.

Plate tectonics (from the Late Latin tectonicus, from the Greek: τεκτονικός "pertaining to building") is a scientific theory describing the large-scale motion of seven large plates and the movements of a larger number of smaller plates of the Earth's lithosphere, since tectonic processes began on Earth between 3 and billion years srmvision.com model builds on the concept of continental.
The concepts of evolution and geologic time are essential components of oceanography (and all other sciences as well!). Earth formed from the accumulation of dust, gases, asteroids, and small planetesimal in the stellar nebula.
During this period in early Earth history conditions on the surface of the planet were probably too hot for oceans to exist.
