The San Andreas Fault and its role in Plate Tectonics and Earthquake Prediction The San Andreas Fault is one of the most widely studied faults in the world. Scientists use an array of methods in collecting data and providing analysis of fault characteristics both past and present. Presently there are many differing hypothesis and models used to describe crustal movements and deformation within the Pacific and North American plate boundary. Historical earthquakes along this fault have proven to be

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

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

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

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

‘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

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

SEDIMENTATION According to Brown (1950)‚ sedimentation is the separation of a suspension into a supernatant clear fluid and a rather dense slurry containing a higher concentration of solid. According to Perry ()‚ sedimentation is the partial separation or concentration of suspended solid particles from a liquid by gravity settling. This field may be divided into the functional operations of thickening‚ whose purpose is to increase the concentration of suspended solids in a feed stream; and clarification

SEDIMENTATION ABSTRACT Sedimentation is the process of separating a liquid mixture of suspended particles into clear supernatant liquid and denser slurry having a higher concentration of solids. This is usually accomplished by allowing the particles to settle through the force of gravity‚ mechanically using centrifugal force‚ or electrostatically using an electric current. Continuous sedimentation tanks are usually used in wastewater treatment facilities to separate suspended particles from wastewater

June 2011 plate tectonics and associated hazards Comment on the extent to which the features shown in the image support the theory of plate tectonics. To begin with we can see that many of the landmasses appear as separated jigsaw pieces with their complementary shaped coastlines. One example of this is how the North Western coastline of Africa could quite easily ‘slot into’ the North Eastern Coastline of America. This suggests that in the history of the Earth‚ these two land masses were once connected
