    These craters are really fun to climb and run down the steep, pumice slopes. Now that the motorcycles aren’t ripping everything up in the craters anymore, the area is returning to its former smooth and sandy glory. Riding motorcycles in the craters at high speed was fun while it lasted, but those days are over. Another

  • Pompeii: A Volcanic Disaster

    811 Words  | 2 Pages

    The volcanologists of today monitor changes in levels of seismic activity from the observatory on Vesuvius, because they know that the “increase of activity in the deep storage of magma causes both earth tremors and volcanic eruptions.” Scientists, through measuring seismic activity, can predict an approaching eruption months in advance. They also know that the activity of Vesuvius is recurrent, and that the “longer the intervals between eruptions, the greater the eventual explosion will be.“ The

  • Understanding Volcanoes Case Study

    1614 Words  | 4 Pages

    Understanding Volcanoes The Earth has a long history of volcanic activity. Currently, there are approximately 1,500 active volcanoes worldwide (USGS, 2014). Whether erupting on the Earth’s surface or deep in the ocean, volcanic activity can result in devastating natural disasters. A thorough background regarding volcanoes and their formation mechanisms, historical data, and damaging impact from previous eruptions is needed in order to understand the complicated science behind volcanoes. Background

    Introduction In the week one lab, members of the class were to classify six unknown rocks into one of the three rock types: igneous, sedimentary, and metamorphic. We were then to use that knowledge, along with other features of the rocks, to determine the rock name. This paper will identify each of the six samples based off the observations of each sample in the lab. The paper will go on to discuss the main properties of igneous, sedimentary and metamorphic rock. This paper will conclude with

  • Igneous Rocks: The Three Different Types Of Rocks

    1428 Words  | 3 Pages

    There are three different types of rocks. We should know about • Igneous • Sedimentary • Metamorphic Sedimentary rocks are made of fragments of other rocks; igneous, metamorphic or sedimentary. They are made when an older rock erodes or weathers to produce sediment, for instance sand on a beach. The sediment is then compacted and cemented together to produce a rock. Sedimentary rocks can also contain individual grains of minerals which have been eroded out of older rocks. Igneous rocks are formed

Like most of the other volcanoes in the Cascade Range, St. Helens is a great cone of rubble, consisting of lava rock interlayered with ash, pumice and other deposits. Volcanic cones of this internal structure are called composite cones or stratovolcanoes. Mount St. Helens includes layers of basalt and andesite through which several domes of dacite lava have erupted. The largest of the dacite

  • Pharah Ahmose Movie Essay

    506 Words  | 2 Pages

    The Pharaoh Ahmose In the movie, Jacobovici associates the Exodus event with the expulsion of the Hyksos. By associating these two events, he believes that the Pharaoh of the Exodus was Ahmose. However there are more than 100 years that separate the Pharaoh of the Exodus and Ahmose, so the theory is invalid. He is not the first to make this error as there was an Egyptian priest in the 3rd century B.C. that also made this connection. Another problem with this theory is that Ahmose drove the Hyksos

  • Stratovolcanoes Case Study

    1922 Words  | 4 Pages

    Stratovolcanoes which are also commonly known as composite volcanoes are composed of many different strata or layers of pyroclastic materials, pumice, volcanic ash and igneous rocks. They tend to have similar eruption patterns that ordinarily results in very significant pyroclastic flows indicated by a fast moving build-up of ash and gas as the upper basal, and pumice and hot lava as the lower basal. From experienced occurrences, these Stratovolcano pyroclastic flows produce great energy and flow speed

    Ebbesmeyer began by reviewing pumice from a nearby volcano, Mount St. Helens, before chasing information about Krakatoa, Toba, Vatna, and a 1962 eruption in the South Sandwich Islands. From his investigation Ebbesmeyer learned many things about history; Research found that ashes were the original drifters, an eruption produced one of the greatest drifts on record, and a plausible hypothesis for the origins of life. Ebbesmeyer examined pumice from the 1962 eruption in a plastic tub and
