Many, many volcanoes exist. However, some of these are dormant while others are active. Volcanoes tend to switch between these two roles. A volcano that was dormant a few years ago may be active now and a volcano that was active a few years ago may be dormant now. This can create many benefits in the area around the volcano, whether it be very close or very far. Volcanoes have affected the environment throughout the years. Volcanoes have affected the environment throughout the years in many ways, good and bad. Some of the bad things to which have happened because of volcanoes is deaths of all creatures, houses being destroyed, and having mass evacuation in a large area. The most deadly volcanic eruption was in the year 1815 in Indonesia, cause …show more content…
One of the many great things that happens after a volcano’s eruption is enrichment of the soil around a volcano. Volcanic eruption creates a large amount of rock and ash within the area to which the eruption occurred, (Source Two: Volcanic Soils, paragraph one, lines one and two). The rock and ash released from a volcanic eruption offers a bountiful amount of minerals that seep into the soil. If you were a plant, growing in this soil would be like eating at Golden Corral every night of your life. Along with this, the volcanic soils easily trap moisture, giving farmers a much easier job tilling the ground, (Source Two: Volcanic Soils, paragraph five, lines two and three). If a volcano were to be erupting near water, then the lava will become cooled into rock and eventually stack up. This is the case for the islands that make up Hawaii. As the lava poured over the peak of the volcanoes and trickled down the sides, it eventually came into contact with the water. This would cool the lava down to the point of becoming solid rock again. After a very long time, the volcanoes made a long stretch of islands, still growing each day. Some of these volcanoes are explosive, but the rest are another type of volcano. These volcanoes do not explode violently as it spews molten rock and ash into the air and land below. Rather, the lava grows to the top of the volcano to pour over the edge. A good example
Volcanos are deadly, can form on islands or mainland, and can destroy mountains and cities. Volcanos commonly form from holes in the earth containing magma. When pressure builds up in these magma chambers, they explode resulting in magma and rock catapulting out into the air. As these volcanoes repeatedly explode, they leak magma, which runs down the side of the volcano. Eventually, the lava cools and transforms into solid rock, building up the volcano to mountain size. An example of giant volcanic eruptions is the Pompeii disaster in 79AD, when Mount Vesuvius erupted and destroyed all of Pompeii. Another example includes, the 1980 eruption of Mount St. Helens in Washington state, which destroyed the whole mountain. Volcanos
Anpother factor that can have an impact on the level of hazard posed by a volcano is the type of plate margin on which it occurs. Volcanoes occuring at constructive plate boundaries are usually much less violent than those occuring at destructive plate boundaries. This is because the magma produced by plates moving apart is Basic, and therefoe has a low viscosity, allowing it to flow easily. The lava is produced from a central vent or fissure and erupts regularly but not usually violently. Also,constructive plate boundaries are often found under the sea and create submarine volcanoes, such as along the Mid-Atalntic ridge, so pose few threats to humans. As a result, the hazards posed by volcanoes at constructive plat eboundaries is relatively low. However, the subduction of one plate under another at destrctive plat eboundaries can form an acidic magma chamber, due to the build up of intense heat. Acidic magma is very viscous and resisitant to flow, meaning that there is often a huge build up of pressure, which can result in very violent and dangerous eruptions involving ash and pyroclastic flow. This can pose a a serious hazard. Pyroclastic flowsa are extremely dense, containing toxic gases at very high temperatures, and can move at speeds over 100km/h. The consequences of such an unpredictable hazard can be extremely seruous
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.
Volcanos are beautiful yet discursive. They may have different effects on towns but some are similar, and some are different. Some may have an effect on both people and cities and the people's mindsets may change on their beloved homes.
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.
A human factor that would cause differences in the hazards posed by volcanoes is settlement, which includes where people chose to live in relation to a volcano. For example, in Indonesia many people settle near Mount Merapi because of the rich and fertile soil favoured for farming. As Indonesia is a poor country many people rely on subsistence farming, therefore are willing to risk everything by settling beside a volcano. Furthermore, in the last eruption in 2010 360,000 people were displaced from their homes, meaning not only did they lose their home but also their livelihood; hundreds also lost their lives. Therefore, the hazards posed could have been minimalised if people chose to settle elsewhere.
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
To begin, a volcano is a mountain with an opening in the top or side that sometimes sends out rocks, ash, lava, in a sudden eruption (Merriam-Webster, n.d.). A volcano erupts when pressure builds inside the mountain. Magma, lava while it is inside the volcanoe, pushes through the weakened crust. When this built up pressure is released, Earth’s plates move causing a volcanic eruption. Also, dangerous flows of steaming lava can reach up to 2,000
Most people would seriously question on why so many people throughout the world live in the immediate vicinity of a volcano, and although we can only see the downside of that, there are benefits from living so close to a volcano. One of the biggest reasons are the soils close to a volcano is full of nutrients and minerals which keep the soil very fertile. This happens because of all of the lava and rock that a volcano releases. This helps soil stay rich with nutrients and gives opportunities to grow fruit, rice or other
Volcanic ashes gathers on streets, lakes, all over, creating disturbances in transport and influencing the neighborhood condition. This hinders business, which in Patagonia for the most part resolves around tourism and agriculture.
Their lava and ash kill plants and animals, but after that, the soil is as rich as Donald Trump. The soil gets enriched by the ash, lava and other tephra that enclosed that land thousands of years ago. Bacteria in the dirt eventually breaks it down into minerals. Soil is made of sand, silt, clay, and organic matter. It can still be loose after the thousands of year, do most farmers plant grass to strengthen the soil. This helps allow people to live on the sides volcanoes without sliding down the mountain.

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.
