“Evaluate how plate tectonics theory helps our understanding of the distribution of seismic and volcanic events” (40 marks) The theory of plate tectonics was first introduced by Alfred Wegener in 1912. He observed the continents an could see they interlock like a jig saw puzzle‚ for example the West African Coastline fits snugly into the South American coastline‚ he suggested that at one point in time there was only one giant continent called “Pangea”. Later evidence was found that proved this theory

subsides along a fault or crack. Benchmark Permanent cement or brass marker in ground indicating a measured elevation. Isostasy Condition of balance or equilibrium in Earth’s crust. Since the upper mantle acts like a very dense fluid‚ the crustal plates float on top of it. Any change in one part of the crust is offset by a corresponding change in another part of the crust. Example of Isostasy

For my activity points‚ I attended the Plate of the Union political event‚ a group that is focused on getting healthy‚ affordable food to all Americans. The Plate of the Union holds monthly meetings at various locations around the city‚ at a variety of restaurants‚ focused on getting healthier foods on the menu‚ ones that support local farmers. This organization needs the government to pitch in‚ especially the President‚ since they would help bring more awareness to the cause and allow more funds

License plate flippers-robbers hate them Number plates being robbed is becoming one of the most common headlines for a local daily. As these can be sold off in the market for a huge sum‚ robbers‚ instead of stealing other car components‚ tend to pry these off. In addition‚ the license plates are easier to remove than any other component. How to save number plates? For saving number plate‚ the easiest bet is to purchase a hideaway license plate. These license plate come for either side of the car’s

Earth’s mantle. Firstly‚ one place where tectonic activity occurs is at oceanic to oceanic constructive plate boundaries. Here two plates diverge or move away from each other‚ pushed apart by huge convection currents In the earth’s mantle. These convection currents are initiated by heat energy produced from radioactive decay in the earth’s core. As the convection currents move the plates away from each other‚ there is a weaker zone in the crust and an increase in heat near the surface. The hotter

Art Criticism of Dinner Plates I went to the Bradbury Museum in the Fowler Center and chose the Dinner Plates which was made by Delita Martin in 2016. She used Lino crayons‚ Stabilo pencil‚ and 200 ceramic plates. The artist does not specify the region where it was made. The first thing I noticed was how many portrait plates there were because it fascinated me how someone could draw all of them. The portraits of women give an atmosphere of empowerment‚ but the table in the center gives a visual effect

Plate Tectonic Assignment 1. The Juan de Fuca and Cocos plates were once part of a much larger plate called the _________ plate. 2. How long ago was this plate the dominate plate? 3. What plate(s) are the remnants of this former plate? 4. What kind of plate boundary exists between the Juan de Fuca and the North American plate? 5. What kind of plate boundary exists between the Pacific plate and the North American plate? 6. What tectonic process is ongoing between Baja California and the North

Volcanic and seismic events are major pieces of evidence towards proving that the plate tectonics theory is valid. The theory of tectonic plates was first posed by Alfred Wenger in 1912. Is the theory of how the earth lithosphere is made up of many separate pieces of the earth’s crust known as tectonic plates. He put forward the idea that all the earth’s continents were once conjoined in one supercontinent called Pangaea‚ and that these continents were moved by convection currents over a period

The History of plate tectonics Before the plate tectonics revolution of the 1960’s geographers had a very basic understanding of global geological phenomena’s. while there had been many theory’s put fort that were used to try and explain these phenomena’s none had been completely successful till finally In the 1960’s The theory of plate tectonics was put forth. It was truly a unifying concept as it helps us to explain and finally understand many different aspects of geography such as the geography

“P” plate drivers and fatal traffic accidents‚ continues to be a serious public health concern with the main age group being between 17-25 (Transport for NSW 2013a). P plate drivers are 33% more likely to have a crash than L plate drivers (Monash University 200). This is due to a number of factors such as: Inexperience Poor decision making Willingness to take risks whilst driving The influence of peer pressure Alcohol and drug use Stress and fatigue. Young drivers are constantly shown
