The plate tectonic theory an explanation of seismic and volcanic events

Plate tectonics, the cause of earthquakes the plates consist of an outer layer of the earth, the lithosphere, which is cool enough to behave as a more or less rigid shelloccasionally the hot asthenosphere of the earth finds a weak place in the lithosphere to rise buoyantly as a plume, or hotspot the satellite image below shows the volcanic islands of the galapagos hotspot. Below is an essay on evaluate how plate tectonics theory helps our understanding of the distribution of seismic and volcanic events from anti essays, your source for research papers, essays, and term paper examples. Major and minor tectonic plates most of the earth is covered by seven major plates and another eight or so minor plates the seven major plates include the african, antarctic, eurasian, north american, south american, india-australian, and the pacific plates.

Plate tectonics: a look at the african plate - introduction the plate tectonic plays an important role in understanding many of the geological aspects and observations and it allows scientists to prevent disasters such as earthquakes and volcanoes. Earthquakes, volcanoes, and tsunamis are all dangerous natural disasters, but they also have something else in common - tectonic plate movement. “evaluate how plate tectonics theory helps our understanding of the distribution of seismic and volcanic events” (40 marks) the theory of plate tectonics was first introduced by alfred wegener in 1912. While once considered revolutionary, plate tectonics theory is now so solidly supported by evidence of many kinds that it is second nature for geologists to explain local histories in terms of such things as the collision of two plates or the movement of a continent from one climate zone to another.

Earthquakes and tectonic plates which is the source of magma and volcanic lava plate tectonics: the theory that explains the global distribution of geological phenomena such as seismicity, volcanism, continental drift, students know major geologic events, such as earthquakes, volcanic eruptions, and mountain building, result from plate. Earthquakes, volcanic activity, mountain-building, and oceanic trench formation occur along plate boundaries in zones that may be anything from a few kilometres to a few hundred kilometres wide to watch a simulated fly-by along new zealand's plate boundary check out this video. Plate tectonics (from the late latin tectonicus, from the greek: τεκτονικός pertaining to building) is a scientific theory describing the large-scale motion of seven large plates and the movements of a larger number of smaller plates of the earth's lithosphere, since tectonic processes began on earth between 3 and 35 billion years agothe model builds on the concept of continental.

Plate tectonics many theories have been put forward to explain the nature of the earth’s surface for example, it was thought that mountains formed because the earth was cooling down, and in doing so contracted. Plate tectonics is the theory that the outer rigid layer of the earth (the lithosphere) is divided into a couple of dozen plates that move around across the earth's surface relative to each other, like slabs of ice on a lake the drawing above is a cross section of the earth showing the components that lie within plate tectonic theory the cross section should really be curved to correspond. Plate tectonics is the process whereby earth continually rebuilds itself — and causes destructive events like earthquakes and volcanic eruptions. It wasn’t until the 1960s that a full explanation began to develop – the theory of plate tectonics this theory explained many pieces of the puzzle that scientists had observed, for example, continental fit, matching geology, past glaciation, movements of the ocean floor and the location of fossils of ancient animals and plants.

The plate tectonic theory an explanation of seismic and volcanic events

The theory of plate tectonics states that the earth’s solid outer crust, the lithosphere, is separated into plates that move over the asthenosphere, the molten upper portion of the mantle oceanic and continental plates come together, spread apart, and interact at boundaries all over the planet. Volcanic and seismic events are major pieces of evidence towards proving that plate tectonics theory is valid a seismic event is the transient motion and release of kinetic energy caused by sudden failure of the earth’s crust, usually felt as shaking or tremors in the rock mass. Volcanic and seismic events are major pieces of evidence towards proving that plate tectonics theory is valid a seismic event is the transient motion and release of kinetic energy caused by sudden failure of the earth's crust, usually felt as shaking or tremors in the rock mass. Future natural events (earthquakes, volcanic eruptions) can be forecasted by combining an understanding of geological forces, such as tectonic plate motion, and by mapping natural hazards in a region.

By monitoring the interaction between the pacific plate and the surrounding, largely continental plates, scientists hope to learn more about the events building up to earthquakes and volcanic eruptions in the circum-pacific ring of fire. Explore the world of earthquakes iris has multiple online tools that allow you to learn about global and regional seismicity convergent, divergent, transform, plate boundaries, rifting, plate, plate tectonics theory, tectonic plates, subduction , subduction zone volcanic tremor. Plate tectonic theory provides an explanation for the formation of volcanic and granitic rocks it explains why mountains occur in some places and depressions in others why the continents are above sea level and the ocean floor is below sea level.

Plate tectonics— the reality behind a theory the study of earth movements is technically known as “tectonics,” so the study of plate movements is called “plate tectonics” (note that it is no longer accurate to call it “continental drift” plate movements, earthquakes, and volcanic eruptions are still occurring today and. Volcanic and seismic events are major pieces of evidence towards proving that plate tectonics theory is valid (40 marks) the theory of plate tectonics states that the earth’s lithosphere (top layer of the earth’s crust) is split up into rigid sections called plates that are moving relative to one another as they move on top of the. Plate tectonics evaluate how plate tectonics theory helps our understanding of the distribution of seismic and volcanic events plate tectonics is a relatively new theory that was developed by alfred wegner in 1912 who came up with the idea of pangea which tells us about the structure of the earth. Plate tectonics theory does help our understanding of the distribution of seismic and volcanic events as by understanding the various plate margins we can then understand what is happening across.
