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 between he events and the plate boundries does this

For millions of years people have lived in areas where two different plates meet. In theses types of areas it is very common for earthquakes to happen and for volcanoes to form. So why if these are such dangerous places to live do people continue to settle here? One reason may be that people believe that the types of natural disasters that are possible will never affect them in their lifetime. It is impossible to tell when a plate movement will occur. Some people are willing to take the chance that

Haiti Earthquake The last major earthquake to hit Haiti prior to the 2010 was in 1984. On the 12th of January 2010 the small Caribbean country of Haiti was hit by a catastrophic earthquake of 7.0 magnitude. The earthquake struck on the afternoon of the 12th of January at 4:57pm and hit south-west of the Haitian capital of Port-au-Prince killing 316‚000 and affecting millions of residents. 1.5 million people were displaced and approximately 250‚000 residences and 30‚000 commercial buildings were

The mother waits until the children are outside‚ playing in the lot‚ before she “began to lick the crumbs from my sisters plate” (Line 19). Her daughter‚ Kayla‚ walks in the kitchen. She is “startled and dismayed by the animalistic actions/ of one so usually a lady” (Line 25-26). This describes the mother’s habits of hiding the tough times from her children. She apparently

A look at the Inner Earth Studying the earth’s interior can help us to understand earthquakes‚ volcanoes‚ plate tectonics and more about the inner earth’s natural processes. In general the earth’s interior has been sorted by Gravity. Heavier elements like iron tend to sink toward the center or core of the earth. Lighter materials‚ the silicates‚ oxygen compounds and water have risen to become part of the crust. This action has created distinct layers within the earth and is still in process today

winds through all major ocean basin like the seams on a baseball. Ridges vary in width from 600 miles to 2500 miles. The mid-ocean ridge represents an area where‚ lithospheric plates move apart and new crust is created by magma pushing up from the mantle . Also‚ the mid-ocean ridge system is an example of a divergent plate boundary. 4.) Briefly describe the process of continental rifting. Where is it occurring today? As crust is pulled apart‚ rifts are formed and eventually become large enough

fire have to do with plate tectonics? The Ring of Fire is a direct consequence of plate tectonics and the movement and collisions of crustal plates.What does the ring of fire have to do with plate tectonics?The "Ring of Fire" refers to a string of volcanoes‚ which create a ring in the Pacific. The relevance to plate tectonics‚ is that volcanoes are created by two plates coming together and pushing up on each other to create the volcano. The Ring of Fire is evidence of high plate tectonic movement in

Earthquake activity in Pakistan is mainly concentrated in the north and western sections of the country‚ along the boundary of the Indian plate and the Iranian and Afghan micro-plates. The Chaman Fault runs along Pakistan’s western frontier with Afghanistan from Kalat‚ in the northern Makran range‚ past Quetta and then on to Kabul‚ Afghanistan. A fault also runs along the Makran coast and is believed to be of the same nature as the West Coast fault along the coast of Maharashtra‚ India. An active

Earth’s tectonic plates. Tectonic plates shift when two separated pieces of Earth’s crust push together because of the pressure of the hot air below them pushing up on the plates from the heat of the Earth’s core. This pressure must be released somehow‚ so when the pressure becomes too great for the plates to withstand‚ one part of a plate gives way to the pressure by rising above the other part of the tectonic plate. This then causes the top plate to overlap and collide with the other plate. This collision

destructive plate boundary. The Nazca Plate which is an oceanic plate in the west is dragged to move towards the South American Plate which is a continental plate in the east. The force driving the two plates to collide is resulted by converging subcrustal currents of magma in the asthenosphere below the earth crust. Such slow collision of the two plates takes place very slowly over millions of years in earth’s history. Due to the heavier density of the oceanic crust‚ the Nazca Plate is subducted
