The earth is made up of tectonic plates these are massive slabs of rock floating on magma ‚as the plates move about‚ they spread apart‚ collide‚ or slide past each other‚ This is the main cause of volcanoes and earthquakes Earthquakes occur in many regions all over the world in some regions they occur more frequently and severely than in others (depending on the location)‚ the main cause of earthquakes is tectonic plates grinding against each other ‚ therefore earthquakes occur

which Japan had ever recorded and can only be explained by plate tectonics. As seen in figure 3‚ the earthquake occurred in a subducting zone where the Eurasian plate and the Pacific plate are converging. Figure 4 shows the continental Eurasian plate being subducting the oceanic Pacific plate and every year the pacific plate travels a distance of nine centimetres towards

Japan is located in three tectonic plate boundaries; the Pacific‚ Eurasian and Philippine Sea plates. A three way destructive plate boundary occurred as a result of a plate movement along the border between the plates. The Kobe earthquake was caused by pressure building as the Philippine Sea plate is subducted underneath the Eurasian plate. The further compressed Philippine Sea plate was affected underneath‚ likely the less compressed continental Eurasian Plate causing an increase of pressure of

crust that creates seismic waves. CAUSE OF EARTHQUAKE Earthquakes are caused by the movement of the earth’s tectonic plates. Earthquakes occur where the earth’s plates meet along plate boundaries (see plate tectonics page for more information on this).For example as two plates move towards each other‚ one can be pushed down under the other one into the mantle. If this plate gets stuck it causes a lot of pressure on surrounding rocks. When this pressure is released it produces shock waves. These

to be where plate boundaries intersect with major storm belts and they are also in areas of high human concentration in low or medium developed countries because this effects whether or not the country will be prepared thoroughly enough and whether it can recover quickly. The Philippines lies on a boundary between the Philippine and Eurasian tectonic plates‚ whereby the Eurasian plate is sub ducted underneath the former; this is defined as a destructive plate boundary‚ as the plates move in series

1. The science of biogeography is the description of distribution of life and the explanation of this description. The description is based on both time and space. This describes how things look and why they are there. It also looks to answer the question – are these features the same over time? Biogeography arose with the theory that life on earth is a non-random distribution. This is the most important observation leading to the field of biogeography. The study of biogeography includes many other

Lutgens & Tarbuck (2014) found “Convection is a type of heat transfer that involves the actual movement of a substance” (p. 177). Plate mantle convection is described by Merriam-Webster’s

with the African plate becoming part of a supercontinent. During one of earlier collisions‚ tremendous heat and pressure were generated. This changed the Smoky sedimentary rocks. For example‚ sandstone became recrystallized into quartzite and shale became slate. The last great episode of the mountain building uplifted the entire Appalachian mountain chain from Newfoundland‚ Canada to Alabama. The mountains then were much higher than they are today. As the African tectonic plate gradually pushed
