Plate Tectonic

At the moment our not so-silent earth seems to be a perfect place where life dwells upon. But in reality, things are really different. This smooth and a solid ground can, at any moment, shake and tremble because of an earthquake. The buildings and highways can easily be destroyed if a mountain rumbles and hot lava erupts. The climate and the working, or in short, the geography of the whole world can change anytime. Questions as to what is the power behind this destruction have developed in the minds of early man which resulted in several myths and mysteries. Finally, in the twentieth century, the plate tectonic theory emerged as an explanation to these earthquakes and volcanoes. Geologists studied the…

Plate Tectonics

The theory of Plate Tectonics covers the extent on how the Earth moves and performs. Findings in the mid 1960s show that the theory is one of the reasons why magnetism, wide distribution of volcanoes, earthquakes, plants, and animal fossils are existing up to the present. The plates usually wriggle like a spinning wheel that they sometimes smash into each other causing a major impact on the Earth’s floor. Likewise, the Plate Tectonics is identified as one of the causes of long-term climate changes, distribution of abound organisms, mountain building, earthquakes, volcanic eruptions, and other major effects of the movement of the continents. As some theorists would explain, the plates composing the Lithosphere, the outer portion of the earth, move…

Plate techtonics

The Earth’s crust is composed of numerous plates which are constantly moving in relation to one another. This movement is responsible for earthquakes, volcanoes, and mountain formation and the theory describing this phenomena is called plate tectonics. Plate techtonics was first described in the 1960’s and unified the theories of contenental drift and magnetic field change. The Earth’s interior is divided into three major sections based on their composition: the crust, mantle, and core. The crust is the uppermost portion, and accounts for less than 1% of its volume. It varies in thickness from 2 to 35 miles and it is this layer. Below the crust is a thick layer of rock called the mantle which is nearly 1500 miles…

How to Illustrate the Plate Tectonic Theory

The Plate Tectonic Theory mainly revolves in the idea that the Earth’s crust was made up of rigid and thin plates that are in motion relative to each other. The theory was first proposed during the 1960 and was later on developed by other scientists and geologists to fully explain the logic behind the formation of continents and oceans, as well as volcanic eruptions and earthquakes. Two of the proponents helped in the development of the theory were Alfred Wegener and Arthur Holmes. Wegener was the first to observe the relationship between the shapes of the seven continents. He saw that their shapes fit together, as if they were pieces from a jigsaw puzzle. From here, he built up the…

The theory of plate tectonics

How does the theory of plate tectonics help to explain the world distribution of earthquake and volcanic zones? The Earth’s crust is made up of seven major plates and several smaller plates. These plates drift on top of the mantle. When two plates meet, they can either be constructive, destructive or conservative. At a conservative plate margin, one plate moves past another. As the plates are not smooth, great amounts of tension build up and earthquakes are made when the tension is released and the plate moves. An example of a conservative plate margin is the San Andreas Fault. The North American plate moves South West at 5cm a year, whereas the Pacific plate moves North West at just 1cm…

Topographical Features at Divergent and Convergent Plate Margins

Divergent and convergent plate margins are both studied in plate tectonics; which is the study of the plates that makeup the lithosphere, their movements and how these movements has influenced changes in the surface’s topography (Strahler, 2011, 389). The driving force that causes these plate movements is the gradual movement of the semi-molten rock that makes up the asthenosphere (Kious, 1996, 28). Features observed at these margins share some similarities but, also vary quite largely. These differences are caused by the different movements displayed at each boundary and the types of plates involved; oceanic or continental. Divergent plate boundaries are where two plates are moving apart from one another (Ritter, 2012). The topographic features that develop at this boundary are…
