Essays On Plate Tectonics-61
Plate tectonics (earthquakes and volcanoes) Introduction Plate tectonics refers to the theory that earth’s outer layer comprising of plates, which have moved throughout the earth’s background information.The theory reveals on the knowhow behind mountains, volcanoes and earthquakes in ancient times as well as currently.

It is only a few that forms within plates due to hot spots activity.

On another case, in some sleep mountains, in the world results because of the interplay that exist between terrain uplift that occurs with plate tectonics and the powerful cutting of streams into hills that lead to erosion causing landslides (Conrad &Lithgow 13).

In addition, scientists found that rock crystals in certain rocks varied from normal to reversed polarity depending on when the rock was formed and solidified .

These patterns mirrored themselves either side of the mid-oceanic ridge in the middle of ocean basins and rock samples were older the farther from the mid-oceanic ridge .

The main causes of earthquakes are the following: breaking of frail rocks and formation of hollow spaces in the Earth’s crust; volcano’s eruption; movement of tectonic plates, which collide with each other, causing heavy pushes.

Making precise prognosis concerning the impending earthquake has been always rather complicated, however,......This calls for more research in order to mitigate further calamities. Such kinds of earthquakes can serve as triggers and alarms for volcanic activity that is about to take place in that area.Works Cited Conrad, Clinton P.& Lithgow, Bertelloni. In 1980’s, earthquakes served as early warning signs for the eruption of Mount St. It is also understood that the......, originally installed to monitor nuclear testing by the 1960s, found that geological phenomenon, such as volcanoes and earthquakes, were mostly found along the edges of tectonic plates .Plate tectonics activity occurs at four types of boundaries.They include the divergent boundaries where new crust is created, convergent boundaries have its crust consumed, collision boundaries have its land masses colliding whereas the transform boundaries has its later sliding against each other (Conrad &Lithgow 13).At the peripheral areas of the Pacific Ocean basin, it contains at its boundaries several plates that are dotted with many active volcanoes to form a ring of fire.The ring provides an excellent example of plate boundary volcanoes. It forms either at mid-ocean ridges or above subduction zones.In conclusion, plate tectonic research is needed for identifying natural hazards such as earthquakes and volcanic eruption before it occurs. Earthquakes generally occur at tectonic plates and most of the eruptions occur in these volcanic regions only.It does not occur randomly but in specific areas such a long boundaries; hence, aiding in evacuation. The movement is caused by the movement of tectonic plates as well as the movement of magma in the volcanoes.During that time, all major continents formed one giant supercontinent called Pangaea.Moreover, due the heat that built underneath the vast continent caused the Pangaea to split apart in around 200 million years ago.
