Subduction

and the mid-metazoic. This event occurred when a continental crust collided with oceanic crust, at a convergent boundary, it causes crust to displace inland on the continental crust while the oceanic crust falls below the other plate via subduction. When subduction occurs the pressure from below causes volcanoes and mountains to form further inland. This would also explain why the rock formation in the Quaternary time period was a pyroclastic…

The Mount Vesuvius Volcano has erupted many times. Since AD 79, the volcano has also erupted repeatedly, in 172, 203, 222, 303, 379, 472, 512, 536, 685, 787, around 860, around 900, 968, 991, 999, 1006, 1037, 1049, around 1073, 1139, 1150, and there may have been eruptions in 1270, 1347, and 1500. The volcano erupted again in 1631, six times in the 18th century (especially in 1779 and 1794), eight times in the 19th century (notably in 1872), and in 1906, 1929 and 1944. In this assignment I am…

width of the trench is 69km (43miles) wide. The length is five times greater than the length of the Grand Canyon. According to the www.livescience.com website The Mariana Trench was created by a process that occurs in a subduction zone where two parts of oceanic crust collide (subduction is a process when one tectonic plate collides with another and submerges under it slowly sinking…

called subduction. The type of volcano formed depends on the type of eruption produced. If there is a lot of superhot magma and many gases creating intense pressure the consequences can be…

When you look at a globe of the earth it is easy to think that the earth has always been this way that the continents and the ocean basins have always been where they are now and they will always be. But if you examine the globe closely you may notice something curious. Some of the continents appear as if they have been joined at one time. A good example of this are the coast lines of South America and Africa. When you compare them with just a little bit of adjustment that they match quite…

generally formed when the underground suddenly breaks along a fault. This sudden release energy that causes the seismic waves that make the ground shake. When two blocks of rock or two plates are rubbing against each other, they stick a little. Great subduction zone earthquakes occur around the world where…

In the wonderful words of Schulz, “Take your hands and hold them palm downs, middle fingertips touching. … The place where they meet is the Cascadia subduction zone. Now slide your left hand under your right one. That is what the Juan de Fuca is doing: sliding steadily beneath North America (Schulz)”. She understands not all of her readers will understand her article completely until they understand how…

This is the biggest earthquake in Japanese history. The earthquake erupted along a subduction zone, this is where two tectonic plates meet and collide (convergent) with each other. Subduction is a process where one of the two plates slides underneath the other plate melting into the mantle, this builds up stress between the two plates and is released as an earthquake, the two plates that performed this subduction were the Pacific Plate and the Eurasian Plate. The plate that subducted was the…

is left behind this stream is called alpine glacier. 4. What is the ablation zone of a glacier and why does the ice look “dirty”? The ablation zone of a glacier is an ice sheet that is low in attitude and when the water melt the ice is less mass subduction. The ice look dirty because after the rain comes it just sit on piles and piles to were it builds up in the glaciers. 5.…

First of all, Meyer addresses a magnitude-9.0 earthquake on the current coast of Oregon and WashingtonIn the article entitled, “A Major Earthquake in the Pacific Northwest looks even Likelier” by Robinson Meyer mentions how unexpected earthquakes could bring devastating consequences with little people informed or prepared. First of all, Meyer addresses a magnitude-9.0 earthquake on the current coast of Oregon and Washington. On January 26, 1700, the Pachena Bay citizens died from a flood and a…
