-convergent

Is it a faster or slower spreading mid-ocean ridge that produces broader and less rugged segments?

-faster

When you have Oceanic-Contintental convergance, which one becomes subducted?

-oceanic

The San Andreas Fault is what kind of boundary?

-transform

The areas where mantle plumes come to the surface are called what?

-hotspots

Much fluid basaltic lava erupts on the seafloor at mid-ocean ridges.
Such eruptions pose little risk to humans because almost all of these occur at the bottom of the ocean. The island of Iceland, where a midocean ridge coincides with a hot spot, is an exception.

    Iceland, the land of fire and ice, is a dramatic yet picturesque and beautiful landscape. Home to magnificent natural features such as glaciers, waterfalls and volcanoes, it is an incredible place to visit. The spectacular island is the second largest in Europe and located between the Greenland Sea and the Atlantic Ocean. It sits on a constructive plate boundary; the violent tug of war between the two plates causes Iceland to gradually get bigger. Iceland is the most volcanically active place in the world, due to tectonic plate activity. Disruptive eruptions occur about every five years. The most recent eruption of Eyjafjallajokull in April 2010, caused havoc both internationally and locally, in this essay I will be discussing which had a bigger impact.…

    Volcanoes are formed on land near coastal areas when a continental plate and an oceanic plate converge. The oceanic plate submerges, due to its higher density, and is pushed deeper and deeper beneath the surface. The high temperature and pressures below melt the rock which creates hot, buoyant magma. Ultimately this magma rises towards the surface and accumulates in a reservoir, known as the magma chamber. The eruption occurs when the pressure within in the chamber surpasses the pressure of the upper rock, magma forces its way through the cracks in Earth’s crust. Magma that is low in gas and silicon dioxide produces thin quickly spreading lava which has a low viscosity, while a magma that is heavily composed of gas and silicon dioxide will yield a thick, viscose magma. The thicker magma builds up and because of this pressure, will cause a large…

    Volcanic eruptions can cause damage within hundreds of miles away. The volcano ash's causes airplane engines to fail, destroys crops, contaminates water, and damages electronics and machinery. When the ash touch's the ground, burying everything, sometimes even make's buildings to collapse. Mount St. Helen's produced more than 490 tons of ash that fell over some many miles. All volcanos are dangerous. They are all scattered all over the world and we don't know when they are going to blow. The three volcanos I picked were pretty interesting. The Pavlof is the most active and one of the most active in North America. The Cero Negro is not as big as the other to volcano's I picked. The Tungurahua is a very large and pretty cool looking volcano.…

    A volcano is an earth hazard that occurs on faults between tectonic plates on a destructive boundary and an eruption is a natural disaster. A primary impact happens immediately after the disaster and before any response like death or collapsing or destruction of buildings. A secondary impact occurs later after the disaster, such less farm produce or a reduction in tourism. The severity of these impacts will differ considerably in a MEDC and LEDC where volcanic eruptions have taken place. These may be seen in the Mount St. Helen volcano eruption as well as in the Iceland volcanic eruption. They may also show that the impacts vary from volcano to volcano, place to place.…

    A volcanic or seismic hazard can have an effect on all people from differing economic backgrounds and the extent of the disaster if often directly linked to the magnitude of the earthquake or the areal extent of the volcanic eruption. This is therefore a result of the occurrence of type of plate boundary. A volcanic eruption produced at a destructive plate boundaries is likely to be much more devastating than at a constructive. This occurs because the volcano is usually composite and therefore expresses rhyolitic lava with low silica content and therefore erupts unpredictably and with great force. At this plate boundary, a denser plate (e.g. oceanic or and older plate) subducts a less dense plate (continental or newer) and this plate descends into the asthenosphere. The plate melts at the Benioff zone due to increased temperatures and pressures and stress is…

    Firstly, one place where tectonic activity occurs is at oceanic to oceanic constructive plate boundaries. Here two plates diverge or move away from each other, pushed apart by huge convection currents In the earth’s mantle. These convection currents are initiated by heat energy produced from radioactive decay in the earth’s core. As the convection currents move the plates away from each other, there is a weaker zone in the crust and an increase in heat near the surface. The hotter, expanded crust forms a ridge. Magma rises up from the mantle in the gap. The lava cools, solidifies and forms a chain of volcanic mountains thousands of miles long down the middle of the ocean eg. Atlantic. There are transform faults at right angles to the ridge. The movement of these faults causes rift valleys to occur. Examples of these landforms created by constructive plate margins are the Mid Atlantic Ridge (MIR) , and the Great African rift valley (GARV). The MIR is the result of the North American plate and Eurasian plate diverging in the middle of the Atlantic ocean. Here, volcanic islands such as Iceland, the Canary islands and ascension island have been created by the rising magma from the mantle. The GARV is an example of where the crust has dropped down between parallel faults to form rift valleys. As the crust subducts into the mantle it melts causing igneous activity below, magma to rise and therefore volcanoes erupt on the surface as a result. Evidence of this volcanic activity is shown by Mount Kenya and Mount Kilimanjaro.…

    Volcanic hazards can be detrimental to the lives of the people who live near the active zone of the volcano in question due to their immense power coming from the centre of the earth however with effective management of the risks the number of deaths, disrupted lives and the economic damage can be reduced greatly. An example I will use of a recent volcano that erupted was Mt St Helens which is an active supervolcano located in Washington, USA - 96 miles south of the city of Seattle and 50 miles northeast of Portland. Clearly there is an active community of people living in close proximity of the volcano, at risk from ashfall and spewing lava.…

    Viewing an erupting volcano is a memorable experience; one that has inspired fear, superstition, worship, curiosity, and fascination throughout the history of mankind. The active Hawaiian volcanoes have received special attention worldwide because of their frequent spectacular eruptions, which can be viewed and studied with a relative ease and safety. The island of Hawaii is composed of five volcanoes, three of which have been active within the past two hundred years. Kilauea's latest eruption still continues as of today. Mauna Loa's latest activity was in 1984 and Hualalai's in 1800-1801, but is likely to erupt again within the next one hundred years. East Maui, or Haleakala, one of the oldest volcanoes, has a long eruptive history and recent activity indicates that the volcano will erupt in the near future. Last but not least, the Loihi Seamount, sometimes known as the "youngest volcano" is an undersea mountain this is still active. Scientists now believe that the hot spots lie in the ocean, deep beneath the volcanoes. These hot spots spew out of molten rock that rises to the water's surface and hardens. After doing this for a long time, the hardened lava forms an island, like the Hawaiian islands (Volcanoes Online).<br><br>The Kilauea volcano is one of the most active volcanoes on earth. It's current eruption started in January 1983, and there is no signs that the current eruption is slowing or will come to an end anytime soon. The U.S. Geological Observatory monitors the daily activities of the volcano, for example-movement of lava flows, earthquakes, surface deformation, and gas production. Kilauea has been monitored ever since, making it one of the better-studied volcanoes. Still there is much we don't understand about the inner workings of this volcano. Unlike most other volcanoes though, Kilauea is approachable. It has been called the "drive up" volcano because of the ease of access to many of its volcanic activity. On February 24, 2000, an article came…

    Volcanoes on a destructive plate margin often lie dormant for years but have explosive and violent eruptions with acidic lava, pyroclastic flows and copious amounts of ash. Because of the length of time that they lie dormant prediction isn’t as easy. Montserrat in the Caribbean experienced a violent eruption in the mid 1990’s. The early activity showed signs of a major eruption so many people were able to be evacuated , giving evidence that preparedness and help decreased the effects of the eruption. Exclusion zones were set up leading 7’000 of the 11’000 inhabitants to be resettled in other countries. This prevented a huge loss of life. The capital, Plymouth, was buried in the ash fall, so with the evacuation all of the inhabitants were moved, meaning the largest population density on the island was prevented from being lost.…
