Volcanoes

about Mount St. Helens and how it is related to volcanoes. In the video about Mount St. Helens, geologists let us know why Mount St. Helen’s is the most deadly volcanic blast in the U.S. Mount St. Helens is a large eruptive cone and is a type of composite volcano that the volcano is composed of many layers of volcanic rocks. The video starts by informing us that this volcano is one of the biggest landslides. In addition, it let us know that volcanoes are dangerous and deadly because they are so hard

Volcanoes People shouldn't live near volcanoes because they are very dangerous and could erupt at anytime causing pyroclastic flows, lahars, and landslides. The volcano eruption in Tambora, Indonesia, in 1815, killed around 92,000 people due to these events that happen when a volcano erupts. One reason why people shouldn't live by volcanoes are pyroclastic flows, pyroclastic flows are high speed avalanches of hot ash,rock fragments, and gases. “These pyroclastic flows which can reach 1,500 degrees

The globalized contemporary society is uniquely vulnerable to volcanoes. A volcano, which is defined as a “vent or chimney which transfers molten rock known as magma from depth to the Earth’s surface” by Geoscience Australia(2015), can be considered to be a cloud with a silver lining for society due to their eruptions. Attributed to factors such as density and pressure, volcanic eruptions occur for several reasons. Grotzinger and Jordan(2014) explains that as magma is less dense than solid rock it

There have been around 1,500 volcanoes during the life-span of earth. Those volcanoes affect many factors in their surrounding regions. Volcanoes can improve the land and assist agricultural farms. Examples include Mount Vesuvius by the Italian city of Naples and Hawaii’s Mauna Loa. Volcanic eruptions, such as Mauna Loa on the island of Hawaii, can reform the surrounding landscape. Ash and deposits of minerals from the eruption serve to richen the soil. After much weathering, the soils are “among

Nope. You could even go to some other places that are safe like in Egypt or somewhere else. Don’t ever go especially near active volcanoes. If you have been experienced a volcanic eruption and have been saved by someone, don’t think that every time you could be saved by someone if stuck in a volcanic eruption again. People should not be allowed to go on the volcanoes even you have been there just for exploring around

I believe that earthquakes are way more dangerous than volcanoes. I believe that they are more dangerous than volcanoes because they can affect any city, state, or country at any time anywhere. The aftermath of the earthquakes are more destructive to an area, and cost way more for the government to clean up. For example, the earthquake that happened in Haiti several years ago devastated the country a lot. The devastating earthquake was a magnitude of 7, and left 230,000 dead, as well as over 300

patterns drastically for months, or even years, at a time. They spew out tons of various gases, volcanic ash-which is pulverized rock-, and rock debris. Each volcano has a different composition, so each eruption has different effects. This means that volcanoes can have a large impact on the weather and climate of a region. How do volcanic eruptions affect local weather, climate, and atmospheric conditions, and how do these factors affect humans? First, eruptions

these things through the many hazards volcanoes presents. Such as lahars, flash flooding, landslides, pyroclastic flows, ash clouds and many others. There are factors which can influence the severity of the hazard and cause differences in them and can be classified into different categories, such as physical, economic, political and social. One physical factor which causes differences in a volcanic hazard is the steepness of the volcano. If the volcanoes sides are of a steep gradient then the

Thesis: At convergent boundaries, mountains, volcanoes, and other natural things can occur because when the plates collide, one plate is forced above the other and this happens because of the density and composition of the minerals and elements in the plates. Story: To start on our journey Jay and I started out towards magnetic north using our GPS (global positioning system) on a beautiful mountain in the great state of Hawaii. You don’t realize how beautiful nature and the world is until

Analyse the factors that causes differences in the hazards posed by volcanoes around the world (40 marks) A hazard can be define as something which poses a level of threat the life, health, property or environment, a volcano can compromise all these things through the many hazards volcanoes presents. Such as lahars, flash flooding, landslides, pyroclastic flows, ash clouds and many others. There are factors which can influence the severity of the hazard and cause differences in them and can be
