Magma

Being unpredictable, it is very dangerous. When the lava is released, it can flow up to 100 mph and nothing can stop this heated avalanche. Hornblende lava is found mostly deep under the ground and is created with water. Blocky Lava is from thick magma that traps gases in the volcano which causes it to explode. Scientist have gone to Mount Lassen to which is in Northern California, they take samples of the gases to discover the source of the water that creates lava. Testing gases from most of…

with volcanoes. How do they work? How hot is the lava exactly? Can you travel down into the funnel of a volcano, and if so how and will you survive? And do all volcanoes function the same way? As a child, we never understood that the beautiful hot magma that flows from the volcano is dangerous and burns everything in its path. Two volcanoes that have always caught my eye is Hawaii’s Kilauea and Japan’s Mount Fujiyama. Both volcanoes are located on an island that was formed due to tectonic plates…

Mid-Atlantic Ridge is in between the African Plate and South American Plate. It lies in between these two plates that are moving away from each other slowly. Although as a result of the separation of the two plates earthquakes occur and magma comes out making new crust. The magma comes out from a series of volcanoes that cool to make new crust. Crust closer to the rift is newer than the crust farther from the rift. The splitting of the African and South American Plate makes a divergent…

got its name. Reason being that it got its name is because it oozes from the sides of the volcano which in Latin its root word means to fall or ooze. There is a difference between magma and its close brother lava. Magma is liquid rock that is still inside the earth and has yet to come out. Lava on the other hand is magma that is no longer inside the earth. The most common type of liquid rock outside the earth is the lava variation is called basalt. There are two words that describe Basalt and…

later. The impact of the irruption can be identified by the composition of the volcano. Most of the volcanoes erupted in the Lineament and the Rio Grande Rift are composed of Basalt which mean the eruption will not be as explosive. Basalt is a magic magma which high Viscosity, and less gases content therefore it will not have not have an big explosion. The lava will slowly come out which gives people more time to react and move to a safer…

Rifting causes thinning and extension of the crust, allowing hot magma to rise from deeper crustal levels and precipitates on the ocean floor as metal-bearing hydrothermal deposits. These deposits are often syn-volcanic faults and fissures controlled. Paragenetic sequence A concept known as the “reconstructive vein”…

Introduction In this paper the Soufriere Hills Volcano will be analyzes in several different parts; an introduction to the Soufriere Hills volcano, the composition of the magma and lava in the volcano, other characteristics of the magma and lava, ash production from eruptions, pyroclastic flows, volcanic activity before the 1995 eruption, the 1995 eruption, cyclic activity within the volcano, and potential hazards of the Soufriere Hills volcano. Soufriere Hills volcano is located in the…

rupture in the Earth’s crust which allows magma/ash/gases to escape from beneath the surface. When magma reaches the surface of the Earth, it is called lava” (). 2. Volcanoes happen around the frame of tectonic plates, causing the plates to move away or crash into one another. 3. When material is much warmer than its atmosphere, and explodes onto the base of a planet or moon from the inside, a volcano occurs. Topic #2: What Causes a Volcano to Erupt? 1. Magma is released when melting of the…

Trans-Pecos Province Magma Types Nathanial Matis 01/12/2014 Trans-Pecos Province Magma Types Nathanial Matis Abstract The Cretaceous was the starting point when the Laramide Orogeny began to fault and fold as a result of tectonic activity which pushed the Farallon plate into the North American plate forcing the subduction of the Farallon. This subduction caused the plate to melt and form magma that either formed laccoliths, or intruded country rock with different igneous compositions. These…

Cataina. The volcano towers 3,330 meters high with the island it sits upon covering an area of 1,190 square kilometers (Branca). Like Stromboli, Etna is in a constant general state of eruption with mild explosive and strombolian eruptions throwing magma and bombs around the island for thousands of years(Branca). Since Etna is located closer to a mass population, and with the constant eruptions, the population of the Island is at risk. Should the volcano ever become violent beyond control, the…
