¶ … Continental Plates and Earthquakes
Natural events or disasters like earthquakes, tsunamis, and volcanoes are dangerous incidents given their significant impact on life and property. Given their devastating impacts, the causes of natural disasters have attracted considerable concern among the public and scientists. One of the most important ways to understand the causes of these events is by examining the science behind them. Even though these events differ in the manner in which they occur, they are largely attributable to tectonic plate movement. Since tectonic plate movement plays a major role in the occurrence of natural disasters, these incidents have relatively similar geological beginnings. An example of a natural disaster whose occurrence is brought by tectonic or continental plate movement is earthquake.
Overview of an Earthquake
An earthquake is basically regarded as a natural event that takes place when two blocks of the Earth slip past each other abruptly (Wald par, 1). The surface where blocks of the Earth slip past each other is known as the fault plane or fault whereas the location where the earthquake begins below the Earth's surface is known as the hypocenter. Since earthquakes take place after two blocks of the Earth slip past each other unexpectedly, they can occur anywhere in the globe. However, most of the earthquakes that take place tend to do so in the region where most of the volcanoes are found i.e. the Ring of...
Tectonic or continental plates are the many different pieces of the Earth's crust that combine together like a puzzle to cover the whole planet. These plates in turn comprise an outer layer of the Earth that is commonly known as the lithosphere that tends to function as a more or less rigid shell. The rigid plates in the Earth's lithosphere are in relative motion and affect humans in various means including generating volcanism, causes earthquakes, and mountain-building ("The Theory of Plate Tectonics" par, 1). Therefore, without plate tectonics and movement of continental plates, the Earth would have less volcanism, fewer earthquakes, and relatively no deep-sea trenches.
The Science of Earthquakes
As evident in the above discussion, earthquakes and other natural disasters are brought by tectonic plate movement. Tectonic plates are puzzle pieces or the many parts that make up the Earth's crust while the edges of these plates are known as plate boundaries. According to Wald, the plate boundaries consists many faults, which are the most common sources of earthquakes throughout the world (par, 3). Tectonic plates are made of rock and drift and move vertically and horizontally upon the surface of the Earth. When these plates move for a long period of time, they change in size through additions…
