Cause And Effect Of Volcanos

There are different types of volcanoes, such as shield volcanoes, composite volcanoes, and cinder cone volcanoes that are mentioned in Chapter 9, page 312 of Earth Science. (Refer to figure 2 for volcano type examples.)

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

The volcanoes are located where there is a divergence or convergence in the tectonic plates and bring their lava from the deepest of the terrestrial mantle. The materials and explosions of these ginates represent a constant risk in the places inhabited by the human being, nevertheless the people ususually live in these areas no matter the risk. On the other hand the volcanos can change the geology of an impressive form, or to cool the temperature of the earth, or to darken the sky. The scientific community increases its efforts to try to understand better what happens in volcanoes, however it is impossible to predict these conditions.

Volcanoes are one of the most destructive, yet, most beautiful things on Earth. They can make a famous city choke in its own ashes in one day, like Pompeii. Or they can turn a once damaging mountain into a graceful and peaceful home for new life, like Mount St. Helen’s. All volcanoes are unique, and no two are the same. Some erupt differently than others, some look different than others, and all are located in different spots all over the world. I learned this while completing the project and the five volcanoes I researched are examples of my discoveries. The five volcanoes I researched were Mount Hood, Mount Mageik, Long Island, Mount Muria, and Las Pilas.

The location of the volcano is also important. If it is situated on a constructive plate boundary then it is generally less explosive, and therefore poses different threats to volcanoes situated on a destructive plate boundary. The volcano may also be situated on a hotspot like in Hawaii, where the eruptions aren’t very explosive. Volcanos which aren’t explosive can pose other threats to lava flows though, such as dangerous gases being released. Like in Lake Nyos, Cameroon where 1700 people died.

The Earth’s outer crust is made up many tectonic plates that move over the surface of the planet. When the plates come collide, volcanoes will form sometime (National Ocean Service). Volcanoes can also form in the middle of a plate, where magma rises upward until it erupts on the sea floor, at what is called a “hot spot” (National Ocean Service). A hot spot is a plume of magma or molten rock that rises from within the Earth then reaches the surface forming underwater volcanoes which may grow tall enough to

There are over one thousand five hundred volcanoes all around the world, and when they erupt, they spew searing hot lava that changes the surface of the earth. Earthquakes, tsunamis, and volcanoes are just three examples of the many geo-processes that are constantly shaping and changing the Earth.

A volcano is defined as a mountain or hill that usually has a cup like crater at the summit. A volcano can be compared to a vent in the earths crust through which lava, ashes and steam are expelled (Volcano, n.d.). There are three main types of volcanoes that scientist have discovered active, dormant, and extinct (howstuffworks.com). Active volcanoes are the ones which have erupted recently, or are expected to blow soon (howstuffworks.com). For example Kilauea volcano on Hawaii is the world’s most active volcano (volcanodiscovery.com). A dormant volcano is one that hasn’t erupted in a long while but has a chance erupt again in the future (howstuffworks.com). Best example there is of a dormant volcano is Mauna Kea which is one of the five mountains that make up the big island of Hawaii (Crain, 2009). And extinct volcanoes are the ones that erupted thousands of years ago and has no possibility of erupting again (howstuffworks.com). An extinct volcano is mount Buninyong which is located in Austria the last time this volcano erupted was a little over ten centuries ago and is now somewhat a tourist attraction.

What is a volcano: A volcano is a mountain created by the earth. It also creates a hole where molten rock (lava) erupts. A volcano is filled of magma but when the magma erupts and is out of the volcano it is now called lava. When a volcano erupts it fills the air with lava fragments. A volcano can cause a lot of destruction like tsunamis, flash floods, mudflows, rockfalls, and earthquakes. Most volcanoes are located where the tectonic plates meet. Most

There are basically two types of volcanos: the active and the inactive ones. And just like in the movies, once the volcano erupts, its lava melts everything

The word volcano comes from the little island of vulcano in the Mediterranean Sea, these fire fountains can reach hundreds of feet into the sky (Lindop). Early Romans believed this mountain belonged to vulcan, the blacksmith of the gods. Within the last twenty years, a volcanologists have been working hard to learn how to predict eruptions and keep people safe.

This is only a general overview of the inner workings of volcanoes and their eruptions. For more infomation, visit Volcano World -- The Premier Source of Volcano Info on the Web.

How volcanoes affect people and environments? A volcano is a mountain or hill having a crater or vent through which lava, rock fragments, hot vapor, and gas are in. Volcanoes can change the weather. They can cause rain, thunder and lightning. Volcanoes can also have long-term effects on the climate, making the world cooler.

Volcanoes and Earthquakes are two of the most intriguing natural disasters that can occur on earth. Unlike hurricanes and tornadoes, they can awaken at almost any point in time throughout the year. These two natural disasters are also different from others because they occur on the layers of the earth itself. Volcanoes, while large to us, are actually small, conical patches of earth that spurt and ooze hot molten lava from the core, and can destroy areas of land triple their size. Earthquakes, on the other hand, are severe jolts felt on land due to the movement of earths tectonic plates. Some may describe earthquakes as being similar to riding a bike down a flight of stairs. The impact of an earthquakes can take down even the largest buildings and strongest structures. All natural disasters can have damaging effects on land, some more than others, and all can be measured or predicted in different ways. Although earthquakes and volcanoes are similar to each other, the two are still very comparable. A few of these similarities and differences include the cause of their occurrence, and how their occurrence impacts the environment.
