There are many different types of volcanos on earth. Like the Cinder Cone Shield and Composite. All of these volcanoes are very unique.most of the volcanoes are made up from rock.
cinder cone volcanos
The Cinder Cone volcano is the most popular type of volcano.The cinder cone is a very steep volcano. It is formed by piles of ash and cinder pile up and then creating a vent. Cinder cone volcanos erupt from a small vent which is circular or oval the lava erupts and make more rock and ash around the volcano's. The cinder cone volcano is a very small volcano.The most famous cinder cone volcano is the Paricutin volcano it crew in a cornfield in mexico it crew up to 2,800 m 9,200 feet.it last erupted in 1952 it was a big eruption that

One of the The most common type of shield volcano is those that form during one long-term eruption.the shield volcano eruptions will usually have ground flows of lava that is capable of traveling great distance. Kilauea island of Hawaii, Began erupting in January 1983, and still shows no signs of abating.another great example of the shield volcano is the barrier in africa.The Barrier Volcano is an active shield volcano located in the north of Kenya. It is last known to have erupted in 1921.
Composite Volcanoes the composite volcano is the last type of volcano this is the tallest type of volcano and can grow as high as a mountain.A composite volcano is also known as a strato volcano. The composite volcano is made of layers of hardened rock. Composite volcanoes are called Composite volcanoes because of their composite layered that build up from constant eruptives. Famous examples of composite cones are Mayon Volcano in the Philippines, Mount Fuji in Japan, and Mount Rainier, Washington, U.S.A. these are all very common types of volcano's.
conclusion overall there is a lot of different types of volcanoes like the cinder cone the shield and competitive they all have their own special things about them there is a lot of volcano in the world and they
Mount Saint Helens and Mount Vesuvius are volcanoes that have erupted they are both different and also the same here are some facts, similarities and differences of both the volcanoes.
Volcanoes are one of the most disastrous yet captivating geological land forms on earth. Many volcanic eruptions are catastrophic, but not all volcanic eruptions are as brutal. The two case studies I have chosen to compare and contrast are the 1980 Mount St. Helens eruption with the eruption of Hawaii’s Kilauea volcano which is still active today.
Mount Rainier is a volcano that is located in the Cascade Range in Mount Rainier National Park, Washington. This volcano is 14,411 feet (4,392 meters) in its elevation. This is the highest mountain in Washington. This volcano is in the same mountain range as Mount Adams, Mount Baker, Mount St. Helens and Glacier Peak. It is known as a stratovolcano which is a large, steep volcano built up of alternating layers of lava and ash or cinders. This volcano is an active volcano and the last time it erupted was in 1894. The largest eruption this volcano has had was 2200 years ago. It has been recorded that the areas has had a lot of small high-frequency earthquakes. Some of them occur daily. According to geologist the cause of this is hot fluids moving inside the mountain. It is composed of two overlapping volcano crater that are 1000 ft. around. This volcano has three different summits; they are Columbia Crest, Point Success and Liberty cap, the highest which is 14,411 feet and the lowest which is 14,112 feet. It lies on the Juan de Fuca Plate. This is a divergent boundary. It was formed by the subduction of the Juan de Fuca Plate and the North American Plate. This volcano also has lahars which are large mudflows that happen in the deposits of sediments that surrounds volcanoes; they can be hot or cold. This volcano includes but not limited to the rock andesite.
Volcanoes have always been a mysterious wonder of the world. Volcanoes have shaped the landscape and the very ground that we all live on. People have written stories of their disastrous eruptions, and painted their marvelous shapes on canvas. The essay will outline some of the more famous volcanoes and how they have impacted are history. Mount Vesuvius that destroy the great city of Pompeii, Krakatoa they spewed deadly ash on small village town, and Mount St. Helen, the only volcano in my own country to every erupt during my own time period.
It has a strombolian eruption style but hasn’t erupted in this century. Another massive volcano in Mexico called Iztaccihuatl is located right next to Popocatepetl. Iztaccihuatl is the third highest mountain in Mexico and is a stratovolcano. It’s nickname woman in the white comes from it looking like a sleeping woman when looking from the valley in Mexico. The last earthquake nearby Iztaccihuatl was on July twenty-seventh two thousand and fifteen. The last time this volcano erupted is unknown but they predict it was less than eleven thousand years ago. Paricutin is a volcano that grew right on top of a cornfield and was witnessed by the farmer. This volcano has a strombolian eruption style which means it has many different explosions that shoot a few meters into the air. This volcano is located in west central Mexico and is currently dormant. It consist of cinder cones that have been active but are not currently. The Tacana volcano is on the Mexico Guatemala border. It’s a stratovolcano that stand four thousand and sixty meters tall. Tacana is currently dormant but last erupted in nineteen eighty-six. When it erupted it spit out some ash which killed some plants but otherwise cause no
Maunaloa last erupted in 1938 and Kilauea has been erupting since January 3,1938. The Hawaii Volcanoes National Park was named a World Biosphere site by UNESCO in 1987. Kilauea is also called the world's only drive-in volcano.
Like most of the other volcanoes in the Cascade Range, St. Helens is a great cone of rubble, consisting of lava rock interlayered with ash, pumice and other deposits. Volcanic cones of this internal structure are called composite cones or stratovolcanoes. Mount St. Helens includes layers of basalt and andesite through which several domes of dacite lava have erupted. The largest of the dacite domes formed the previous summit; another formed Goat Rocks dome on the northern flank. These were destroyed in St. Helens' 1980 eruption.
Volcanic activity is a fairly common event for the Earth. Generally, there are anywhere between 50-60 small eruptions a day) These eruptions barley register onto the Volcanic Explosivity Index (VEI), similar to the Richter scale for Earthquakes. It ranges from zero to eight, zero being the weakest and eight being capable of mass extinctions. Major Volcanoes generally erupt every 100-200 years. Every 10,000 years, A Volcano erupts with so much power that they can cause Mass Extinctions.
The volcano of Mount Etna has been on this earth for about 500,000 years and is still currently active. This volcano is located on the east side of Sicily, Italy and stands 10,900 feet tall with a base circumference of 93 miles; it also still has a series of eruptions dating back to 2001. Mount Etna is considered a stratovolcano which means it’s built on top of many layers of lava and ash made from previous eruptions. What makes this volcano so unique is that it has many eruption styles ranging from extreme violent ones to regular lava just flowing from the mouth of it. About “25% Sicily 's population lives on Mount Etna 's slopes.”
Volcanoes. The naturally forming landforms that can look remarkably beautiful. Gentle slopes, or high rising heights with snow caps and greenery that seems to attract many tourists and sightseers around the world. These magnificent landforms can also cause major destruction and can produce forces that can explode, burn, and create a great deal of damage. Two of these extravagant wonders of the world is the Mount Saint Helens composite volcano in Washington, US, and the Mauna Loa shield volcano in Hawaii, US. These landforms have a eruption history of many colors. One has a great power in eruption, but another has a eruption that is quiet and gentle. In comparing these two volcanoes there are many likes, and dislikes, to consider. So the following
Stories about volcanoes are captivating. Myths come in different versions, but all of them are capable of capturing yours, and everybody’s imagination.
Super volcanoes are formed when magma rises from the mantle to create a scorching reservoir in the Earth's
Convection currents deep in the mantle of the earth, begin to well up towards the surface. As the pressure increases, it sets the crustal plates in motion. There are different kinds of mountains - Volcanic, Folded, Fault-block, and Dome mountains. Volcanic mountains are formed when magma comes up through cracks in the Earth’s crust and explodes out of lava and ash. The Hawaiian volcanoes, Mt. Hood, Mt. Etna, Vesuvius, and Mt. Saint Helens is an example of volcanic mountains.
There are four major types of study that make up a volcanologist or team of volcanologists. These include physical volcanologists, geophysicists, geodesic volcanologists and geochemists (What does a volcanologist do?, n.d.). Physical volcanologists study the actual processes that make up a volcanic eruption. They also study the deposits made during the eruption. Where the rocks from the eruption were distributed and what their makeup is.
