Cinder Cone Volcanoes Research Paper

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.

Feel free to stretch, it's been a long ride. We will be stopping by a restaurant later to get some lunch. In front of you, you can see Humphreys Peak, the tallest mountain in the San Francisco Peaks. The San Francisco Peaks is actually a volcanic mountain range and is part of the San Francisco volcanic field. The peaks were once a stratovolcano but is now eroded and are the remains of the volcano. It is the only stratovolcano in the San Francisco Volcanic Field. The tallest mountain, Humphreys Peak, is about twelve thousand, six hundred and thirty-three feet in elevation, which is also three thousand, eight hundred and fifty-one meters tall. In fact, Humphreys Peak is the tallest point in all of Arizona. Also in this area, are more than six hundred volcanoes. Most of the volcanoes found here are basalt cinder cones. These volcanoes are relatively small. They are also usually less than one thousand feet in elevation. Another fact about these basalt cinder cones is that they are formed within a range of a couple of months to a couple of years. The San Francisco Volcanic Field also has several lava domes. Lava domes are formed by dacite and rhyolite magmas. Both of those types of magma are very rich and high in silica. So, as a result, the dacite and rhyolite magmas are very viscous and thick. As a matter of fact, the magmas are so viscous is thick that when volcanoes erupt, the magma tends to pile up and form very steep sided masses, which are the domes.

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.

Mauna Loa, located in Hawaii, is the largest active volcano is the world. Mauna Loa is a shield volcano, comparable to many of Earth’s other large volcanoes. According to Caitlin Kelly with USA Today, “Shield volcanoes are formed by many lava flows that build up and create long, gentle slopes, rather than a steep-sided mountain.” Shield volcanoes emit low viscosity lava, which means the lava flows easily. This creates an enormous landform with a wide base. Mauna Loa makes up 50% of the Big Island of Hawaii, with an area of 2,035 square miles. In Hawaiian, Mauna Loa means “Long Mountain.” Data from the Hawaiian Volcano Observatory shows that Mauna Loa rises approximately 13,680 feet above sea level, and 16,400 feet below. Furthermore,

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

There are 1,900 active volcanoes on Earth (National Geographic, 2016). Mount St. Helens, located in the Cascade Range which stretches across Washington is one of the volcanoes located in The United States. When a volcano erupts it can causes extensive damage in the wilderness and nearby civilizations.

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.

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

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.

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

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?

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

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

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.
