GEOL 1003 Lecture : Ch8 PlateTectonics With Notes
Document Summary
Subaerial mor iceland: this dramatically exposed rift separates the north american and eurasian tectonic plates. In december 2004, a tsunami struck offshore sumatra (m9. 0 along the sumatra-andaman fault). Along the same fault line, a m7. 7 earthquake occurred in october. How does the understanding of plate tectonics inform your reaction to seemingly unusual phenomena that periodically affect. "when the plates along the fault-lines move, they create heat and the expanding gas blasts through the fissures in the earth"s crust, propelling the entire sea floor to the surface. " What is plate tectonics: plate tectonics = lithospheric plates move in relation to (but independently from) other plate segments. Explains many observations, including tsunamis like those induced in sumatra or the sudden appearance of a mud island. Based on fossil distribution: hypothesis of subaerially connected landmass that subsequently sunk . Problem hard to explain the distribution of modern mammals on.
