The movement causes the crust to be very “thin The thinning allows the magma to come to the surface and form a volcano. Volcanoes can also occur at tectonic plate boundaries because Volcanoes form where the earth’s crust is thin and the magma can flow to the surface easier. This happens mostly at the edge of the plates. Volcanoes lastly can occur at subjection zones because that is where the crust is being forced down into the lower levels and becomes magma also becomes higher pressure as it moves down something must move up to balance out, the magma moves up forming a volcano.
Volcanoes can occur in many different places, mostly near the water. Volcanoes can erupt at any time of the day. They occur all over the world in different regions and continents. Volcanoes can sometime erupt when the plates collide because when one plate can slide under the other. This also causes the mantle underneath to melt. The magma pushes up, melting more rock. If a crack opens in the crust, magma spews out. Volcanoes can also erupt when the plates move because that makes heat and it causes the mantle to melt into magma. The magma comes up through the crack between the plates.
Volcanoes can erupt because of the magma is trying to float to the surface. If the magma has water and gas, it has that because when the magma reaches the surface the water and the gas will suddenly expand into steam and gas, which will make the volcano erupt! See volcanoes can have many different reasons for erupting. There are a lot of different volcanoes in many different shapes and sizes. One volcano called the Cinder Cones. They are the simplest type of volcanoes. Most cinder cones have a bowl-shaped crater and they rarely rise more than a thousand feet or so.
Cinder cones can mostly be found at near western North America. Also another type of volcano is called the Lava dome. Lava Domes are very small but they flow lava at a large distance. Lava Domes can be found at most subjection zones. Lastly another type Of volcano is called the shield volcano, they are built almost entirely of fluid lava flows. Shield volcanoes have diameters of 3 or 4 miles and a height of 1 ,500 to 2,000 feet. Shield volcanoes can be found at Japan, Lynda in Ethiopia, Underarm in Australia and etc. To conclude, there are many types of volcanoes, they can be each mound at a different size and shape.
Volcanoes can be very dangerous and you don’t know when it could erupt. Some ways you can know when the volcano is going to erupt is when you monitor the volcanoes behavior. You can look back at what months and years the volcano erupted. You can also look up the history of that particular volcano in the past and present. Another way you can know when a volcano is going to erupt is when you monitor the gases coming out of the volcano. Most active volcanoes have gases coming out the fumaroles escaping to the surface. Finally another way you can know when a volcano is about to erupt is when plants near by just die suddenly.
Also the color of the lakes and ponds nearby change color due to all the dissolved material in them. And the air temperature changes quickly. Volcanoes can be a ticking time bomb, so you have to be on the lookout and monitor the volcano. Volcanoes eruptions are very serious and massive. A volcano called Mount Vesuvius in Naples, Italy, is one of the most dangerous volcanoes in the world. Mount Vesuvius erupted in AD 79. Within hours, the cities were buried in she, and the volcanic cloud blocked out the sun completely, leaving the area in darkness.
Another serious volcano eruption was when Nevada Del Uric erupted in Colombia. It killed 27,000 people as they were sleeping. The volcano is 32 feet tall and it still stands there today. The eruption was small but the city was all ice and snow, and when the lava hit the city it all melted into water picking up mud, trees, and etc. Lastly another dangerous eruption was when Mount Tent erupted in Italy. The eruption destroyed and/or damaged more than 40 towns, leaving between 20,000 and 60,000 people omelets.
It erupted in 1669, and large parts of the city were destroyed. Since 1500 BC, more than 150 incidents Of eruptions have been recorded. This shows how dangerous many volcanoes can be. Volcanoes come in many different types that causes destruction in the world. Volcanoes can occur all over the world. Volcanoes can erupt anytime of the day. There are many different types of volcanoes in different sizes and shapes. Volcanoes eruptions are also very serious and massive, there are many stories about volcanoes erupting and lots of people being killed.
