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 Tectonic Theory helps our Understanding of the Distribution of Seismic and Volcanic Events (40 marks) The Plate Tectonic Theory developed in the late 1960’s‚ when people noticed how continents either side of the Atlantic Ocean seemed to almost fit together. Francis Bacon‚ an English Philosopher was aware of this as early as 1620. Topographical and geological evidence built up and allowed Alfred Wegener to publish a theory in 1912‚ suggesting that the continents were once all joined

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

Hazards are anything that could cause damage to humans or buildings. Many volcanic and seismic events happen that cause hazards to humans. Often the world’s poorest people are hit the worst‚ however wealthier countries can also be adversely affected. The Kobe earthquake in Japan 1995 struck at 5.45am. Many people were asleep in bed‚ causing the hazard to be increased because the people were unaware. Although many Japanese buildings were of aseismic design‚ the roofs of their houses were designed

“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

Volcanic and Seismic events are major factors towards providing that plate techtonics theory is valid. Discuss the extent to which you agree with the statement. (40 marks) Throughout close analysing we can see patterns in the occurance of seismic and volcanic activity worlwide. These patterns can be used as clues to help discover why such events occur‚ and it is clear that both volcanic and seismic activity is most abundant on and around plate margins. However despite there being a clear link
