inner core. As the core of the planet heats up from the decay of radioactive elements deep in the earth‚ the rocks melt‚ forming magma. This heat needs to be released and allowed to escape to the surface. An eruption hole‚ or vent‚ is created through which burning hot molten rock and gases are released to the surface of the earth. The build-up of the ashes and lava flows (magma that has been released from the earth) that are released around the hole accumulate to create a volcano. These happen most often

June 2010 The hazards presented by volcanic and seismic events have the greatest impact on the world’s poorest people.” To what extent do you agree with this view? PLAN: 1. What is a hazard- volcanic hazards include tephra‚ lava‚ pyroclastic flows‚ volcanic bombs and seismic hazards include earthquake‚ tsunami‚ liquefaction‚ landslides 2. Human issues- proximity to lowland coast‚ ability to adapt to change‚ socioeconomic effects‚ impacts within a community‚ difference in rich and poor‚ urban and

The Three Pigs II: Vengeance There were once three swine that lived in a house of astoundingly well constructed crimson brick. It held up to the tremendous typhoon of an immensely powerful and terribly malevolent wolf. The wolf‚ however‚ refused to admit his mortifying defeat at the hands of three hogs that he thought were akin to a dirt devouring earthworm in the bowels of the planet in comparison to his might. He was starving for vengeance. Six years after the wolf’s defeat‚ the three pigs

Race Your Marbles to Discover a Liquid’s Viscosity Which Liquid Has the Highest Viscosity? In this project we will determine the viscosities of 5 separate liquids. The liquids we will test are corn syrup‚ honey‚ vegetable oil‚ milk‚ and water. We will find their viscosities by dropping a marble into each of these liquids and measuring the time it takes for it to reach the bottom. Before we conduct the experiment‚ we must first understand what viscosity is. “Viscosity is the quantity that describes

Volcanic and seismic events are major pieces of evidence towards proving that the plate tectonics theory is valid. The theory of tectonic plates was first posed by Alfred Wenger in 1912. Is the theory of how the earth lithosphere is made up of many separate pieces of the earth’s crust known as tectonic plates. He put forward the idea that all the earth’s continents were once conjoined in one supercontinent called Pangaea‚ and that these continents were moved by convection currents over a period

Thermite Background: Thermite is a powder made from aluminum powder and a metal oxide [usually iron oxide (Fe2O3‚ known as rust)]. The thermite reaction is a redox reaction‚ where Aluminum reduces the oxide of another metal. For example‚ when using iron oxide (as I did) the equation would be Fe2O3(s) + 2 Al(s) -> Al2O3(s) + 2 Fe(l). Black or blue iron oxide (Fe3O4) could also be used. Other examples of possible oxides are manganese thermite (MnO2)‚ Cr2O3‚ and copper thermite (CuO). Aluminum can

EOSC 114 – Final Review Notes Get A’s or die trying. Jason Kim Unit 1: A Fragile System At least 3 earthquake recording stations are required to find the location of the earthquake epicenter. A single recording station can only calculate distance‚ but not direction; to cover all possibilities‚ a complete circle is drawn around that station. If only two earthquake recording stations are used‚ the circles will overlap at two points. Data from a third recording station will eliminate one of

Volcano Essay A volcano is an opening‚ or rupture‚ in a planet’s surface or crust‚ which allows hot magma‚ volcanic ash and gases to escape from below the surface. It is a raised area of land‚ which usually forms a mountain or hill. Volcanoes are generally found along tectonic plates- diverging or converging. There are four main types of volcanoes‚ dome‚ shield‚ composite cone and cinder cone‚ which are based on their shape. There are three levels of activity‚ active‚ dormant and extinct.
