Volcano Is A Volcano, Volcanic Eruptions, Earth, And Earth

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

Volcanoes can be found throughout the entire world and are formed when there is a rupture in the mantle of the Earth's crust. This effect allows the output of volcanic lava, ash, and various types of gases. These tectonic plate breaks are normal, the planet Earth is divided into 17 tectonic plates and consistently move against each other forming shifts from low to high intensity. It can cause displacement of earth or water.

Furthermore, acid magma is more likely to produce clouds of smoke and ash due to the explosive nature of the eruption it causes, than thinner, basic lava. Ash clouds, such as the one caused by the Icelandic volcano when it erupted in April 2010, which caused severe disruption to European air space, causing thousands of flights to be cancelled due to concerns over the hazards posed to air passengers travelling through the ash cloud.

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

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

The term volcano originates from name of the Mediterranean island called, Vulcano. The people in the area called it this because it expelled smoke like a chimney, and they believed that it was evidence of the god of fire, Vulcan, working under the earth

Volcanos typically formed as a consequence of plate tectonics. In fact, they tend to form when plates converge into each other. In the process of subduction, one plate of the lithosphere, cupped by oceanic crust, slides beneath another one, giving origin to a subduction zone. While sliding down, heat is generated and water is released, causing the formation of magma that rises up to the surface and forms volcanos parallels to overriding plate. The Pacific West region of the United States is known for presenting this type of structure in which the oceanic lithosphere pushes towards the continent and sinks down into the asthenosphere.

A Volcano is a mountain or hill that has a crater running through it filled with lava, rocks, gas and hot vapour that will erupt. There are three types of volcanoes, there is the Cinder Cone volcano which is the smallest, the Shield volcano which is in most cases the biggest and the Composite volcano which can be the most deadly.

According to the Geological Association of Canada, volcanology is the study of volcanoes and in particular the way in which volcanoes erupt. Volcanologists investigate the processes that go on inside the Earth that lead to volcanic eruptions. Their work involves the study of the movement of magma and the surfaces of volcanoes, particularly their gas content. Volcanologists also study the interior of volcanoes because it reflects the importance on how the Earth work.

Each eruption caused a hot rock called magma from inside earth to be forced out to the surface called lava. Some of the eruptions caused magma that was liquid to flow out lava while at other times the magma was solid bursting out molten rock. Volcanos are essential to life on earth for various reasons like adding

According to Middlemost (1988)’s basic definition, magma is a heated rock-forming substance that is created within a planet and exists only below Earth. When magma escapes to the Earth’s surface and is extruded, they are known as lavas. Grotzinger and Jordan (2010) suggests that magma mainly comes from the asthenosphere- the upper part of the mantle.

Volcano – A vent in Earth’s surface that admits ash, gases, and molten lava. 3. Hotspots create new volcanoes E. Types of Plate Contact 1. Divergent plate boundaries - two plates move away from each other a) Causes seafloor spreading 2. Convergent plate boundaries – two plates move closer to each other a) Formation of mountains 3.

A volcanic eruption happens when ash and hot rock build up and explode out of a volcano.a A volcanic eruption can happen at any time.Volcanic Eruptions can happen any where there is a volcano and volcanic eruptions don’t happen in mississippi fun fact there is a volcano under mississippi.volcanic eruptions can last 1 to 20 days and are rated by V EI-0 toVEI-8 a volcanic eruption can be named but they’re named by where they happend.
