Mount Vesuvius – Italy Hypothesis: The impact of active volcanoes overlooking settlements pose as huge threats. With eruptions of volcanoes comes mud, ash and rocks leading to settlements being buried under the debris. Volcanoes also lead to lava flows and ash-and-gas explosions which damage and destroy many settlements/towns around the volcano. In worst case scenarios, eruptions of volcanoes lead to death of people and wildlife. Therefore we can deduct that a volcano is a geographical problem…

year-round fog, iconic Golden Gate Bridge, and cable cars, but is at risk for a major earthquake. San Francisco is built on the north american plate with it moving against a transform boundary, with the Pacific plate. A transform boundary is when two plates slide against each other, causing many earthquakes since San Francisco is on the west coast of the north american plate. One earthquake that you might’ve heard of is the 1906 San Francisco Earthquake, which was caused by the transform…

“The last judgment is here, cried Candide” (Norton, p.425) this is what he said when the earthquake of Lisbon hit. What we can see from this statement is how easily influenced Candide is, all it took was an earthquake and already it is the end of the world. Now granted this is an earthquake that has devastating potential, but we don’t see any other character making a statement like this. Also, Candide's major error is that he never seems to develop his own thoughts and feelings about life…

Introduction: What is a harmful problem that waves cause? Tsunamis cause mass destruction and death whenever they hit land. Tsunamis are seismic sea waves/ huge ocean waves that are created by undersea disturbances and earthquakes. There are 3 main types of tsunamis: local tsunami, regional tsunami and distant tsunami. A local tsunami affects coasts less than 100km away from it's source and generally hits within an hour of occurring and sometimes within 10 minutes. Local tsunamis are…

It is defined as a movement in the oceans that has a direction and is continuous. These abiotic features of the environment are created by the average or mean flow of the seawater, winds, Coriolis Effect, salinity and temperature difference, cabbeling and breaking waves. Coriolis Effect is the result of the rotating Earth. The rotating Earth changes the straight line path of the current and winds as they travel. Thus, the currents due to this in the Northern part move to the right side whereas…

could be where two continental crusts collide or the subduction of oceanic crust below continental crust. When two continental crusts collide compression forces crust to displace both up and down. In a subduction zone when an oceanic plate falls below a continental plate compression aides to create volcanoes on the continental crust. In both cases the compression could have forced the sediment to begin to fold as the cross section shows. This corresponds to the mountain building event marked by…

Introduction Adakites are volcanic rocks that are diagnostic of high temperature, high pressure conditions, (Stevenson, 2005). Their composition ranges from felsic to intermediate, and are characterized by assemblages of plagioclase, and often amphibole, and are identified by their unique geochemical signatures. Adakite is named Adak Island, Alaska, where it was first documented,(Defant and Drummond, 1990). They are often formed through the partial melting of a young subducting slab of…

The location consists of two plates meeting in western California. The boundary between them is a zone of faults, the principal one being the San Andreas fault. The San Andreas fault is a strike slip fault. The Pacific Plate which is on the west, slides horizontally northwestward relative to the North American Plate located on the east. This causes earthquakes along the San Andreas and its associated faults. The San Andreas fault is a transform plate boundary; it accommodates horizontal relative…

1 Camila Rejalaga Sept 24,2017 Earth 101 Volcano Project 2. What we learned from Mount Saint Helens: Surprises and New Science from the Eruption (Brochure) Welcome to Mt. Saint Helens Park Visitor Center! To better understand Mt. Saint Helens we must first go back to 1980. Although some of you might not have been born yet it was in that year that the US experienced its most destructive volcanic eruption in its history. Most of you might have already guessed it but it happened right here…

Poseidon He is known as Poseidon in Greek mythology and Neptune in Roman mythology. He is the god of the Mediterranean Sea, the god of horses, and the god of chariots. He has the power to cause storms and shake the earth through earthquakes, hence his nickname Earth Shaker. It is said the whenever he gets frustrated or angry, the seas get rough and, strong storms attack the mighty oceans. That is why sculptures and paintings often display his violent character, but he is also pictured in…
