When the tectonic plates are pulled apart, slide by each other or collide, tectonic activity occurs creating earthquakes as well as volcanoes. Earthquakes can both be created by a volcano or act as an igniter for a volcanic eruption. The spatial relationship and distribution that exists with these forces of nature include the importance of the rate of heat loss the planet reflects on from plate tectonic activity. From my understanding from the article, our planet needs plate tectonic activity in order to remain alive. These two forces of nature in a way deliver crucial benefits during their destruction. The class lectures and this assignment have taught me that there are numerous earthquakes throughout our country and the world. The connections between land and water, and the types of moving involved with both are scary yet fascinating at the same time. Learning about the Salt Lake area and the outcome of different levels of devastation put things into a different perspective for me as far as where I really should be living. Learning that the earth is the only planet that still has erupting volcanoes and the Ring of Fire is the most seismically and volcanically active zone in the world.
