de Fuca Plates. The oldest crust is along the Japan Trench and Marianas Trench. This is the outermost layer of the Earth. 6) Now look the Atlantic Ocean Basin‚ and compare the pattern of older/ youngest oceanic crust to what you say in the Pacific Ocean Basin. Are these ocean basins alike or different; could they be both? The Atlantic Ocean Basin is quite different from the Pacific. The Atlantic Basin has more activity vs the Pacific by way of plate tectonics. There are more plate boundaries in

Maura Gongora 12th December‚ 2014 MCB 3020L- Section 018 Unknown #16 Abstract This report contains the background information on gram positive and gram negative bacteria‚ which will aid in understanding the use of specific laboratory experiments to distinguish between the two types of bacteria. Included are the materials and methods used to identify the gram positive and gram negative bacteria and methods which also differentiate between microbes of each group. The implications of the methods of

The island lies in the Pacific Ring of Fire that is characterized by having active volcanic and tectonic activity. Due to its geomorphology‚ the area is very vulnerable to environmental hazards such as earthquakes‚ tsunamis‚ and

designed to impact on a rock particle placed between a fixed and a moving plate (jaw). The faces of the plates are made of hardened steel. Both plates could be flat or the fixed plate flat and the moving plate convex. The surfaces of both plates could be plain or corrugated. The moving plate applies the force of impact on the particles held against the stationary plate. Both plates are bolted on to a heavy block. The moving plate is pivoted at the top end (Blate crusher) or at the bottom end (Dodge-type

Mt Etna is a stratovolcano ( another name is a composite cone) which means that multiple layers of ash and solidified lava have formed this volcano. Mount Etna is formed on a convergent plate boundary‚ on two of the world’s active continental plates- the African and The Eurasian Plate. The Eurasian and African plates are moving past each other along most of the boundary‚ making it a

A volcano may appear when magma in the mantle rises through the plates. 4 Types of Boundaries Destructive Constructive Collision Conservative Destructive Boundary (Pacific) Oceanic with Continental If there is friction between two plates there may be an earthquake Constructive Boundary (Atlantic)

theory about the formation of the Himalayas started to take shape in the year 1912 when German meteorologist Alfred Wegener developed his Theory of Continental Drift. According to Wegener‚ the earth was composed of several giant plates called tectonic plates. On these plates lie the continents and the oceans of the earth. The continents were said to have formed a single mass at one point in time. From this single mass‚ today’s continents have "drifted" apart from each other over a period of millions
