“Volcanic and seismic events are major pieces of evidence towards proving that plate tectonics theory is valid’ Discuss the extent to which you agree with this statement (40 marks) The plate tectonics theory was made by a German named Alfred Wegener. He stated that a single continent existed about 300 million years ago named Pangaea and that it split into two continents of Laurasia in the north and Gondwanaland in the south. Today’s continents were formed by further splitting of the two masses

“Volcanic and seismic events are major pieces of evidence towards proving that the plate tectonic theory is valid” Discuss the extent to which you agree with this statement (40). The theory of plate tectonics 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 the plates converge‚ diverge or move past each other. These plates are

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 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

“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

Discuss the evidence for tectonic plate movement There has been a variety of different evidence for tectonic plate movement but the main evidence was Wegener’s theory which was based on a variety of different evidence from several sciences. Alfred Lothar Weneger was a German polar researcher‚ geophysicist and meteorologist‚ he first thought of this idea by noticing that the different large landmasses of the Earth almost fit together like a jigsaw puzzle. In 1912‚ he proposed his explanation – the

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 volcanic

‘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
