Fuji are all examples of strata volcanos. Shield volcanoes are made of thousands of thin lava flows. Because the flow of the lava is generally fast, it is able to travel far from the vent. The resulting volcanic land form has a broad base and gentle slopes. Shield volcanoes are the largest volcanoes.
A Composite volcano is also known as the Stratovolcano, this volcano is built by many eruptions that have happened throughout the course of history. Composite volcanoes are tall cone shaped mountains. These volcanoes erupt in different ways at different times. Shield volcanoes are the largest volcanoes on earth. These volcanoes are built almost entirely of lava.
Volcanoes are a part of earth's beautiful mountains, but they are no ordinary mountain. Volcanoes come in all shapes and sizes,but are capable to doing the same damage. Volcano have several different types of volcanoes, for example one of them is a cinder cone volcano which stands at 1,200 feet and has a 30-40 degree slope according to Owlcation.com. Another type of volcano is called a shield volcano which rises up to 30,000 feet in the air and
Large mudflows flowed down the volcano, which have become important pieces to the eruptive cycles of this volcano. Later, there was another eruptive period, along with the pyroclastic flows of hot pumice and ash, was dome growth. Mt. St. Helens has been one of the most active volcanoes, but has experienced long periods when it has been dormant as well. It was considered a composite volcano, which was a symmetrical cone with steep sides.
One example is Mount Saint Helens. Mount Saint Helens is one of the largest volcanic mountains in the world, if not the largest. The Ring of Fire is also known to produce earthquakes. The reason they produce these earthquakes, is because tectonic plate movements in the earth. One fact you might not know is that seventy-five percent of the world’s volcanoes occur along The Ring of Fire.
When it finally does release, it is volatile and is very explosive. Mount Vesuvius is a composite, or strato-volcano, and is the reason it had such a large explosion. Other famous composite volcanoes include the following: Mount Fuji in Japan, Mount Shasta and Lassen in California, Mount Hood in Oregon, Mount St. Helens and Mount Rainier in Washington, and Mt Pinatubo in the Philippines. (Jeffrey Kluger) The final type of volcanic composition is cinder cone volcanoes. Cinder cone volcanoes are different from shield and composite volcanoes because cinder cone volcanoes only grow to about a thousand feet, and they usually erupt from many openings.
The volcano erupts over and over again if it stays active. As those layers build up the volcano grows and it becomes ginormous. This process takes thousands of years! A volcano is formed when the plates in the Earth’s crust moves. There are giant plates under the surface of the Earth or the crust.
Since the beginning of modern science, volcanoes have drawn the attention of scientists around the globe. However, it wasn’t until about 25 years ago that our understanding of the physical and chemical processes that drive volcanic eruptions increased drastically. Due to our advances in geochemical and petrological sciences, we have been able to more accurately conclude as to why and how a volcano erupts. As a generalization, volcanologists primarily focus on the science behind how magma forms and moves to Earth’s surface, and how the specific chemical properties of magma (and the lithosphere though which it moves) contribute to eruptive activity. Volcanic ash is also significant in the volcanology, differing slightly with each eruption.
Underneath the volcano, the magma sets in a place called the magma chamber. As soon as certain amount of magma and gas is trapped in the magma chamber, the volcano erupts with a large explosion. Stratovolcanoes are the ideal volcano. They are identified by gradual slopes that begin at the bottom and work their way up to steeper slopes at the top of the volcano. Though there are many volcanoes in the world, one that has been on high watch for the past 4 years is Mount Merapi.
After significant time, the hard lava forms a volcanic mountain. Volcanoes can form in many different sizes and shapes. They can look like a cone, have steep looking flanks, or look as if they were long cracks in the earth’s crust. (Plummer et al., 2000). If the mountain is very tall, then there is a greater chance that it was formed from past eruptions.
