Mauna Loa Carbon Dioxide
1,498 words... locked into the melted minerals. If volcanic rocks erupt on the earth's crust, such as the Andean volcanoes, then magma can interact with carbonate rocks such as chalk as it travels up through the mantle or lower crust, picking up carbon dioxide on the way. In subduction zones, where the ocean floor goes down into the mantle some carbonate rocks do get taken down and melted, recycling their carbon dioxide content, but this is a minor source compared with the mantle. Carbon is quite common de...

Sulfur Dioxide Mount St
825 wordsThe two case studies I chose for my paper are the Mount St. Helen and Mount Pinatubo volcano eruptions. In this paper I will compare and contrasts the two volcanic eruptions on an individual, economic, and globally implications. The Mount St. Helens eruption took place on May 18, 1980. The eruption was designated as a five on the volcano index. The Mount Pinatubo eruption took place on June 15, 1991, and it was designated as a six on the volcano index. Mount Pinatubo eruption was about ten times...

Lava Flows Earth Crust
1,090 wordsVolcano: defined is a mountain or hill formed by the accumulation of materials erupted through one or more openings (called volcanic vents) in the earth's surface. The term volcano can also refer to the vents themselves. Most volcanoes have steep sides, but some can be gently sloping mountains or even flat tablelands, plateaus, or plains. The volcanoes above sea level are the best known, but the vast majority of the world's volcanoes lie beneath the sea, formed along the global oceanic ridge sys...

Explosive eruptions can eject liquid and semisolid lava as well as solid fragments of volcanic or nonvolcanic rock that have been carried along by the rising magma before eruption. Very violent explosive eruptions are called Plin ian eruptions, after Roman naturalist Pliny the Elder. These eruptions can last for several hours to days and eject a large amount of pyro...

Lava Flows Shield Volcanoes
1,961 wordsA volcano is a mountain or hill formed by the accumulation of materials erupted through one or more openings in the earth's surface. Most volcanoes have steep sides but sometimes they can slope down or even be flat. The volcanoes above sea level are the best known, but the most volcanoes lie beneath the sea, formed along the global oceanic ridge. Volcanic eruptions in populated regions are a significant threat to people, property, and agriculture. The danger is mostly from fast-moving, hot flows...

Million Years Ago Hot Spot
346 wordsA hot spot is said to be a volcano that is recognized by an age progression from one end of the chain to the other. An active volcano commonly serves as an "anchor" at one end of the chain. After minutes of searching the web I found a hot spot that was not included in the Hawaii or Yellow Stone hot spots. I found my hot spot near India by the island of About 66 - 68 million years ago present-day India was above the hot spot and great volumes of basaltic lava erupted to produce the Deccan Traps. ...

Square Miles Miles North
1,106 wordsLateral Blast The sudden removal of the volcano's north flank released pressure on the hydrothermal and magmatic system within the volcano, triggering a devastating lateral blast to the north. The abrupt pressure release, or " uncorking, " of the volcano by the avalanche can be compared in some ways to the removal of the cap from a vigorously shaken bottle of soda pop, or to punching a hole in a boiler tank under high pressure. The northward-directed lateral blast of rock, ash, and hot...

Volcano Began Erupting People On The Island Montserrat
552 wordsMontserrat is a volcanic island in the Caribbean. On the southern end of the island is the Soufriere Hills volcano.
