Seismic Waves Plate Boundaries
1,198 words... dates. An example of the most well known and studied fault is the San Andreas Fault located of the coast of California. The origin of volcanoes: Hot spots, can be found on plate boundaries or inside the plates. The hot spot is a place deep inside the Earth that begins to form molten lava from extreme heat conditions. It will quickly rise up, pushing and melting its way to the surface resulting in a volcano. Because of the constant moving of the plates, the volcano will be carried away from t...

Oceanic Crust Mid Ocean
1,629 wordster> Describe the frequency, origin and distribution of earthquakes at mid-ocean ridges, ocean basins, subduction zones and continental shields. Earthquakes are happening almost everyday all over the world. Most of the time earthquakes are not strong enough to be felt by people, but the shaking caused by an earthquake is recorded by a seismogram. These are located all over the world at different points. Only occasionally will a larger magnitude earthquake strike and cause damage to the...

Oceanic Crust Ocean Basins
1,875 wordsThe Cordilleran Orogeny The earths lithosphere can be divided into two major structural features: ocean basins and continents. Ocean basins, as we discussed in another essay, are formed at spreading ridges and consumed at subduction zones. The continents are a different story. How did the continents originate, and how have they changed over time? The origin of the earliest continental crust is still relatively obscure, but the evolution of the continents over time is not: the continents have cle...

The earth can be divided into concentric layers. These can be distinguished from one another through varying chemical composition, temperature, density and phase. The inner most central body is called the core. This consists of two parts: the inner and outer core. The inner is understood to be solid due to the immense pressures, and the outer core...

Charleston S C Volcanic Eruptions
2,884 wordstrembling or Natural Disasters earthquake, trembling or shaking movement of the earths surface. Most earthquakes are minor tremors. Larger earthquakes usually begin with slight tremors but rapidly take the form of one or more violent shocks, and end in vibrations of gradually diminishing force called aftershocks. The subterranean point of origin of an earthquake is called its focus; the point on the surface directly above the focus is the epicenter. The magnitude and intensity of an earthquake i...
