Cinder Cone Volcanoes Research Paper

There are 20 volcanoes scattered throughout northern, central, and southern California: Medicine Lake, Mount Shasta, Brushy Butte, Twin Buttes, Silver Lake, Tumble Buttes, Eagle Lake, Lassen, Clear Lake, Mono Lake, Mono Craters, Long Valley, Inyo Craters, Mammoth Mountain, Ubehebe Craters, Golden Trout Creek, Coso, Lavic Lake, Amboy, and Salton Buttes. Some of these volcanoes are active, while others are not. A majority of the volcanoes are inland, with Clear Lake Volcano being the furthest west, located near Sacramento and San Francisco. (Refer to figure 3 to see main .k California volcano locations.)

Of the volcanoes that are located in the United States there are two which are world renowned for their activity and their power to change the region surrounding them. The two volcanoes would be Mount Saint Helens and Mount Kilauea. In order to get a better understanding of these volcanoes we will be comparing and contrasting them as well as talking about how they were formed and when they last had an eruption.

Volcanoes are one of the most destructive, yet, most beautiful things on Earth. They can make a famous city choke in its own ashes in one day, like Pompeii. Or they can turn a once damaging mountain into a graceful and peaceful home for new life, like Mount St. Helen’s. All volcanoes are unique, and no two are the same. Some erupt differently than others, some look different than others, and all are located in different spots all over the world. I learned this while completing the project and the five volcanoes I researched are examples of my discoveries. The five volcanoes I researched were Mount Hood, Mount Mageik, Long Island, Mount Muria, and Las Pilas.

The location of the volcano is also important. If it is situated on a constructive plate boundary then it is generally less explosive, and therefore poses different threats to volcanoes situated on a destructive plate boundary. The volcano may also be situated on a hotspot like in Hawaii, where the eruptions aren’t very explosive. Volcanos which aren’t explosive can pose other threats to lava flows though, such as dangerous gases being released. Like in Lake Nyos, Cameroon where 1700 people died.

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

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

Volcano eruptions happen more often that you know it. They even happen in Alaska. Earlier this year a volcano in Alaska had erupted. This was Pavlof Volcano. This massive eruption had a large cloud of ash and debris more than 7 miles into the air. Pavlof Volcano is 625 miles southwest of Anchorage. Lava shooting out of the volcano was seen by many people near the area. Strong winds had also carried a lot of ash and debris throughout the interior of the state.

Some of these landforms are shield volcanoes, cinder cone volcanoes, composite volcanoes, and lava plateaus. Another landform that can also be created is a caldera, which results from the collapse of a volcanic mountain. When thin layers of lava harden on a wide, gently sloping mountain, a shield volcano is formed. Volcanoes that are high in lava may produce ash, cinders, and bombs. These materials form a cone-shaped hill around the vent. This is called a cinder cone. When volcanoes alternate between lava and ash, cinder, and bombs, a composite volcano is formed. According to the California Earth Science Textbook, “Composite volcanoes are tall, cone-shaped mountains in which layers of lava alternate with layers of ash.” The volcano gets a pattern of different colors because of

Volcanoes exist all around the world. My volcano is Mount Rainier before we get into that here are some things about all volcanoes. A volcano is a point in the earth where magma pushes up through the crust and spits out ash,gas and lava. Volcanos can be deadly, the gas can kill you and the ash can burn also bury you. There are different kinds of lava, one is called pahoehoe it is a fast moving lava that is smooth looking. Another one is aa, a slow moving lava that is sharp looking like glass. There are also different kinds of lava flows, one is the pyroclastic which is an explosive lava flow that throws out rocks and lava. The magma/lava comes from a chamber in the crust called the magma chamber. There is a long pipe that takes the magma/lava

Laki was formed from a hot spot which is where molten rock reaches into earth's crust. The volcano erupted with over 140 separate volcano vents. Laki is a shield volcano which is created entirely of lava, it is sloped, and large. Laki’s elevation

Characterized by towering summits that explode with the scorching innards of the planet, one would think that volcanoes are something from a fantasy novel. But no, they’re found everywhere from Hawaii, to California, to Alaska. They come in many different shapes and sizes, and they all erupt in a certain way, causing different hazards. So, what makes these behemoths tick?

Shield volcanos are located in different places such as Hawaii, Iceland, and the Galapagos Islands. Each and every one varies in shape and size; however, each one looks like a slightly sloped mountain. The Magma and Eruption style of a shield volcano is quiet with fluid lava that can travel very far which is what gives shield volcanos their unique shape.

This is only a general overview of the inner workings of volcanoes and their eruptions. For more infomation, visit Volcano World -- The Premier Source of Volcano Info on the Web.

A shield volcano is a type of volcano usually built almost entirely of fluid magma flows

There are many cinder cone volcanoes in New Zealand such as the Maungarei in Wellington which is 443 ft tall. Another example of a cinder cone volcano is Kilauea in Hawaii which
