fifty homes, forty-seven bridges, fifteen miles of railways and one hundred eighty-five miles of highway. Mount Saint Helens had been dormant for the past one hundred twenty-three years. The volcano was also a strato-volcano. The volcano is part of the Cascade Volcanic Arc. A volcanic arc is a chain of volcanos formed over a subduction plate. The Cascade Volcanic Arc is a major range of volcanoes stretching all the way from British,…

liquid rock, once this magma reaches the conduits (channels for conveying water or other fluid) the gases explode and may burst out the sides of the cone in addition to the summit crater. Mt Vesuvius is a Stratovolcano also known as a composite volcano. Stratovolcanoes are also called composite as they are made of built up of alternating layers of lava flow, ash and blocks of unmelted stone. Stratovolcanoes form above the subduction zone at plate boundaries. They are known for erupting with…

Titanium was discovered in 1791 by William Gregor as a inclusion of a mineral in cornwall, it was named for the titans of greek mythology. The name is derived from the titans, the sons of earth goddess of greek mythology. Titanium has 22 protons, 26 neutrons, and 22 electrons. The atomic number of this element is 47,867. Titanium is a lustrous transition metal. William Gregor was a man who was interested in minerals. He recognized the presence of a new element. The boiling point for this element…

karen Plate Tectonics There are two main ways scientist learn of earth saunterer is rock samples are rock sample from looking at the rock that comes from defence babanic explosion. The second main ways selected learn about earth centered is seismic waves seismic waves inderal travel thpro put where they travel speed path. Inconclusive this is how scientists learn about earth…

Plate tectonics is a scientific theory that describes the large-scale motion of Earth’s Lithosphere. The theory was believed to be developed around 1912 by Alfred Wegener. Wegener introduced the fact that all of today’s continents were once a large supercontinent (Pangea) and how they slowly drifted to their present positions. This idea was developed by simple observations such as the fact that the African and South-American coast lines fit together like pieces of a puzzle and that fossils and…

ever heard the joke, the joke about the volcano that blew off its top? Has it ever crossed your mind that it might actually happen, that it might actually blow off its top, possibly fill with water and create a lake, become national park?! Well if you haven’t, this unique volcano is called Mount Mazama, and it has transformed into the beloved Crater Lake. Mount Mazama is located in Oregon state, and had been overlapping from a composite volcano to a shield volcano, as well as spreading it’s ash…

and 5.5 miles long. (Bagley) There were a series of smaller eruptions a few months before the largest and final eruption. Local fishermen and villagers marveled at the clouds of ash and smoke looming above the giant volcano. They weren’t exactly sure what was going on with the volcano, but they had no idea of the power waiting to explode from its three…

Volcanoes exist all around the world. A volcano is a break in the Earth’s crust that produces lava, gases, ash. Some volcanoes are active and some volcanoes extinct and dormant. Magma usually forms 30 to 120 miles beneath Earth’s surface. Most volcanoes are tourist attractions and most people like to climb them and to live near them to produce some heat to there house when the people don't have any heat. Villarrica is located in the country of chile. Villarrica has a 4 star warning and…

to. You do not have to because Yellowstone National Park has a super volcano that is the strongest one, and is larger than Rhode Island and Delaware combined, and has the fastest bird in the world. It is interesting that there is a supervolcano somewhere in the United States. A supervolcano is a volcano that is powerful enough to eject 240 cubic miles of magma. As well as the supervolcano, Yellowstone has another active volcano (Park Facts). An interesting…

erupting in 1991, the volcano had been dormant for around 400 years. During the years of 1990 and 1991, there were many events that led to the eruption of Mount Pinatubo. A magnitude 7.8 earthquake struck 100 kilometres north east of the mountain on July 16, 1990. This event is contributed to the reawakening of the dormant volcano which triggered many small earthquakes around the volcano. The actual eruption of Mount Pinatubo didn’t occur until June 15 1991. The volcano is located on the…
