Document Summary

We are sitting on a tectonic time bomb. We are about 1100m from the hayward fault. When the ground shakes where i am seismic waves. When the ground breaks along a fault seismic source. Pattern is similar for eq and volcanoes. Eq occur along major ocean features like ridges and trenches. Eq occur under some major mountain ranges. Main argument was that the coastlines of african and south. America fit together: geologically, it was the same type of rock. When he presented his theory, he was ridiculed. At the time, geologists thought that the earth was rigid. It took 50 years for his theory to be accepted. Theory that describes how the earth is in constant motion includes earth, ocean, etc. The surface of the earth is in constant, perpetual motion. They are moving, hence they collide, separate, scrape along one another. Divergent: established mid-ocean ridge, new rift zone, new ocean, mid-atlantic ridge, east african rift and red sea.
