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

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’ 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

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 either continental or oceanic and are

The natural hazards caused by plate tectonics are more a result of human factors than physical ones. Discuss to what extent do you agree with this statement? [40 marks] A natural hazard is a threat of a naturally occurring event that will have a negative effect on people or the environment. The Earth’s lithosphere (crust) is divided into tectonic plates which are constantly in motion due to the convection currents caused by heat cycles in the mantle‚ driven by radioactive decay in the Earth’s core
