Thesis: Earthquakes have been a natural part of Earth for many years and are caused by a shift in the 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

EARTHQUAKE Introduction An earthquake is the result of a sudden release of energy in the Earth’s 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

David Kelleher Geophysicists Discover Slippery Secret Of Weaker Underwater Earthquakes http://www.sciencedaily.com/videos/2007/ 1007-underwater_earthquakes.htm In December 2004‚ an underwater earthquake triggered a string of tsunamis along the Indian Ocean with devastating effects. Now‚ scientists have found ways nature is preventing some deep ocean earthquakes and save lives. Strong underwater earthquakes start off silent -- until their tsunami waves roar on shore‚ destroying property and

Earthquakes An earthquake is a shaking or trembling of the crust of the earth caused by underground volcanic action or by the breaking and shifting of rock beneath the surface. The volcanic action and shifting rocks create strain which continues to build to a sudden release of pressure resulting in a shock wave. The vibrations produced in the crust can vary from barely noticeable to enormously destructive. Shock waves can be classified into two broad categories. Waves that send particles oscillating

History of Earthquakes Throughout its prolonged history‚ the Earth has experienced a myriad of earthquakes that range from minor to major; some of the earthquakes had no fatal impacts while others were extremely catastrophic. However‚ these earthquakes were undeniably vital in shaping the modern world; without them‚ some magnificent landscapes that we see today would not exist. In the following paragraphs‚ we will be discussing the causes and effects of massive earthquakes‚ and exploring earthquakes

COT essay The Indian Ocean trade network began to flourish as trade increased between African and Asia. Powerful city-states flourished along the eastern coast of Africa. The city-states traded with inland kingdoms. It took small steps like that to create a large complex trading network that worked through the Middle East and India and throughout Africa. The trading history of Indian Ocean displays more change than continuity because of the involvement of different cultures wanting different things
