Are Earthquakes Becoming More Frequent: GCSE Case study

During this object lesson study, I will be meditate a question be earthquakes be becoming more frequent? passim this investigation, I will be explaining how earthquakes atomic number 18 detected, how they atomic number 18 earnd, presenting an line of descent for and against this debate and so forth At the end of my case study, I will formulate an opinion base on the evidence that I f all in gathered. I will in addition be questioning the reliability of my sources of information. If you want to analyse the sources yourself, the links to the websites will be operable on the bibliography page.I will also acquire statistics to further support the argument being made by some(prenominal) sides. Diagrams will give visual guardianship to help understand this controversial issue. (Picture of earthquake damaged buildings) What are earthquakes? Firstly, Earthquakes are unremarkably caused when rock pipe suddenly breaks along a fault. This sudden release of sinew causes the seismic waves that make the ground shake. When both blocks of rock or two plates are rubbing against each other, they stick a little. They dont just slide smoothly the rocks ginger nut on each other.The rocks are placid pushing against each other, but not moving. After a while, the rocks break because of all the pressure thats built up. When the rocks break, the earthquake occurs. During the earthquake and afterward, the plates or blocks of rock start moving, and they occur to move until they get stuck again. The spot underground where the rock breaks is called the focus of the earthquake. The place unspoiled above the focus (on top of the ground) is called the epicentre of the earthquake. (picture showing epicentre of earthquake) Earthquakes can cause a lot of damage.Earthquakes have the mogul to uproot trees and send them crashing into buildings. They can part landslides and avalanches, and cause flooding and tsunamis. Human structures are also at risk. It is interesting t o grade that tall buildings will sustain the to the lowest degree damage if they are located forthwith at the epicenter. This is because they can withstand the up-and-down social movement of P-waves. S-waves, on the other hand, occur farthest away from the epicenter, and cause the greatest centering by shaking buildings from side to side. These buildings are often knocked off their foundations.
