PPT-Tectonics from the Cambrian into the Future

This map illustrates the breakup of the supercontinent Rodinia which formed 1100 million years ago The Late Precambrian was an Ice House World much like the presentday httpwwwscotesecomearthhtm. The word tectonics derives from the Greek tektonikos, meaning "pertaining to construction." At night they use their natural jet propulsion to maneuver up over 325 meters to feed. . Why an “explosion”?. What were conditions like at the end of the . Proterozoic. ?. . Supercontinent was breaking up. Earth habitable. ? . Earth is the only planet in the Solar System with plate tectonics. The outer crust of the Earth is broken up into regions known as tectonic plates. These are floating on top of the magma interior of the Earth and can move against one another. When two plates collide, one plate can go underneath another.. Zachary Gallegos.
