The Earth is constantly moving. The earth is not stable because‚ the plates are all ways moving.There is different boundaries for the plates in the earth there is convergent‚ Divergent‚ and transform boundaries. The transform boundaries rub together and causes enough friction that when the potential energy lets loose it creates an earthquake. convergent boundaries we’ll come together that can help make mountains because when one plate is more dense than the other plate‚ the more dense plate will

The Werewolf By Angela Carter Fairy Tales tend to start off dark and progress to have a happy ending or‚ failing that‚ to teach a lesson. Angela Carter does an excellent job of this in her short story “The Werewolf”. This is her take on “Little Red Riding Hood”. This is not the classic spin on the original fairy tale however‚ in Angela’s take on it we will explore ageism‚ sexism‚ and greed. Though the story casts a once-upon-a-time aura‚ the lessons learned from it are as modern as the IPhone

About 320 MYA‚ Africa collided with PNA‚ which formed the Alleghanian Mountains. We know that the Alleghanian Orogeny happened because the Alleghanian Orogeny formed the Appalachian Mountains‚ and the remains of the Appalachian Mountains are still here today. 260 MYA‚ when the Alleghanian Mountains started eroding‚ the Appalachian Mountains eroded‚ but not completely‚ so the parts that did not erode are the parts we see today. During this time‚ the Iapetus Ocean was narrowing and subducting‚ and

Earth Quake Cause and Effect Essay BY: Jean Rosario Teacher: Jessica Heyett An earthquake‚ one of the most destructive natural disaster‚ consists of rapid vibrations of rock near the surface of the earth. It is the most terrifying of all natural disasters and has brought fear since ancient times because of its sudden unpredictable occurrence and enormous capacity of destruction. Earthquakes can effect earth‚ people‚ and property in everyday lives. Earthquakes change the earth’s formations in different

The Earth - it’s an intricate formation of land and sea‚ rock and metal‚ but how can the movements of the continents be explained‚ or how do deep ocean trenches affect us? The three main theories that explain how these things work are sea-floor spreading‚ continental drift‚ and plate tectonics. These are the theories that give us explanation as to why the continents move‚ how plate tectonics work‚ etc. These theories were formed by different scientists and with different forms of evidence‚ some scientists

AN EARTHQUAKE IN AUSTRALIA Australia has a relatively low rate of seismicity due to its location towards the centre of the Indo-Australian Tectonic Plate. Earthquake activity is much higher around the margins of the Indo-Australian Plate‚ for example In places such as Indonesia‚ Papua New Guinea and New Zealand. Nevertheless‚ many historic earthquakes have Occurred in Australia and Geosciences Australia’s database (QUAKES) contains information on tens of thousands Of historic earthquakes in the

1. What is the ultimate cause of movement within the earth’s crust? ANSWERS: Radioactive decay generates the heat energy that powers movements of plates. 2. What causes earthquakes? ANSWERS: Friction between the rough edges of slowly moving segments or plates of the earth’s lithosphere result in a series of jerky starts and stops which is the direct cause of most earthquakes. 3. What is a fault? ANSWERS: Faults are fractures in rocks along which displacement has taken place 4

Discuss the view that the impact of earthquake hazards depends primarily on human factors (40 marks) Earthquakes are an example of seismic activity caused by the build-up of tension at the three types of plate boundaries: destructive‚ constructive and conservative. The pressure is suddenly released as the plates jerk past each other‚ sending out seismic waves from the focus that travel through different parts of the earth. The movement of convection currents within the Earth’s mantle causing the
