Pangaea and Plate Tectonics
from Luchans Science Hosted by Jared Luchans
Fossil and geologic evidence support that our Earth used to be composed of one giant landmass called Pangaea which started breaking apart approximately 240 million years ago and is still moving today. Sea Floor spreading at the Mid Atlantic Ridge provides new rock and older rocks as you move toward the continents Africa and South America, which are recorded to be moving apart from one another at about 2.5 cm per. year. . . . plate tectonics will continue to reshape our planet as there will be more ovement, Earthquakes, Volcanoes, and large plate movements over time. . . . What will our planet look like in another 100 million years?
