“Discuss the Extent to which volcanic and seismic activity are evidence for plate tectonic theory” (40) Plate tectonics is the theory that explains the structure and motion of the Earth’s lithosphere. The theory states that the Earth’s crust is split into large sections called tectonic plates‚ and these move relative to one another creating boundaries at which plates converge‚ diverge and move past each other. Alfred Wegener pioneered the theory of continental drift in the early 1900s which he supported

Evaluate how plate tectonics theory helps our understanding of the distribution of seismic and volcanic events. Plate tectonics is a relatively new science. It’s partially explained in the sense that we still don’t know fully about how the plates came together‚ what they were before they were the seven continents we know today. We already know‚ or have a theory‚ about what our world was like a long time ago and so if we already know that the plates can pull and push against each other‚ then surely
Free Plate tectonics
Plate tectonic theory is a widely excepted theory that the Earth’s lithosphere is made up of plates‚ both oceanic and continental‚ which slowly move due to convection currents in the mantle and the asthenosphere. However‚ it is very hard to be certain as we can’t see the structure of the Earth‚ so some people do not agree with it. This theory saw the introduction of what we know today to be tectonic plates. Tectonic plates occur where there is radioactive decay in the core and temperatures are extremely

Evaluate how plate tectonics theory helps our understanding of the distribution of seismic and volcanic events(40) The global seismic and volcanic activity is concentrated along the margins of the earth’s plates‚ which are broken pieces of the crust and are moved by convection currents that are caused by heat rising and falling inside the mantle generated by radioactive decay in the core. This movement of the plates and the Earth’s inner activity is called plate tectonics and can cause seismic and

ALGORITHMIC AND MATHEMATICAL PRINCIPLES OF AUTOMATIC NUMBER PLATE RECOGNITION SYSTEMS Introduction It is believed that there are currently more than half a billion cars on the roads worldwide. All those vehicles have their vehicle identification number ("VIN") which states a legal license to participate in the public traffic. No vehicle without properly mounted‚ well visible and well readable license plate should run on the roads. The license number is the most important identification

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

‘Evaluate how plate tectonics theory helps our understanding of the distribution of seismic and volcanic events’ In 1912‚ Alfred Wegener published his theory that a single super continent named Pangaea once existed about 300 million years ago. He proposed that Pangaea then later split into two continents of Laurasia in the north and Gondwanaland in the south and that today’s continents were the result of further splitting of these two land masses. Where the plates split are known as plate boundaries

The plate tectonic theory is the theory that describes large amounts of movements in the Earths lithosphere‚ whereby Continental and Oceanic crust is moved‚ destroyed and made from this. The idea of plate tectonics builds on other concepts such as continental drift‚ where continental plates over millions of years move‚ however the concept of continental drift was not accepted for some time‚ and there were many other theories to suggest that something else took place‚ as the idea of the earth moving

Explain how plate tectonics can help our understanding of the distribution of either earthquakes or volcanic eruptions. Plate tectonics can help us understand the distribution of earthquakes and volcanoes very easily‚ it is recorded that main earthquake and volcanic zones are clustered along plate boundaries and more powerful ones are near destructive and conservative plate boundaries. Over time we have learnt that earthquakes that occur on a constructive plate boundary cause little hazard to

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 underlying semi-molten mantle. These plates are either continental‚ The North American Plate‚ or oceanic‚ The Nazca Plate. Tectonic plates are powered by convection currents‚ which is the circular
