The theory of plate tectonics states that the Earth’s lithosphere is broken up into many different pieces separated by jagged cracks. These are called the tectonic plates. They are in slow‚ constant motion pushed by the convection currents in Earth’s asthenosphere. This theory explains the process of sea floor spreading at mid-ocean ridges‚ and subduction at deep ocean trenches. It was proposed by J. Tuzo Wilson in 1965. He combined the discoveries of Harry Hess and Alfred Wegner to support this

‘How might criminology help explain corporate crime?’ Corporate crime is a wide-ranging term‚ covering a vast range of offenses with differing types of perpetrators‚ modes of operation‚ effects and victims (Hale et al. 2005‚ p.268-9). Types of corporate crime range from financial crimes including illegal share dealings‚ merger‚ takeovers and tax evasion to crimes directly against the consumer‚ employment relations and crimes against the environment. In the past criminology has put little energy

Rock and Roll evolved from blues in America and started in the 1920’s but only became popular in the 1950’s. Rock mainly uses a fast paste beat of drums‚ electric guitar‚ bass guitar and acoustic guitar. Some famous Rock musicians such as Elvis Presley were in the early stages of when Rock was popular

WHAT ARE ROCKS? What are Rocks? Making up most of the Earth’s crust‚ rocks are usually defined as a mixture of common minerals. Rocks can be hard or soft‚ as small as a grain or as large as a building. Combined with the effects of weathering and vegetation (vegetation can also weather rock as the tree or bush is "yanked" out of the ground by forces of wind or by merely falling over after it has died. Root systems tend to go under the surface and attach themselves to

Mini-Literature Review The Ox Mountain range is in County Sligo. ‘’The Ox Mountains lie along Sligo’s border with Co. Mayo’’(Libraries 2010). A strip of ancient rocks - gneiss‚ schist and granite - form the bedrock of the Ox Mountains’’(Geological 2016). The uplands of the Ox Mountains are wild and mainly covered by blanket bog. Some parts of the Ox Mountains are heavily forested. To the north and south of the Ox Mountains is farmland that is mainly underlain by Carboniferous Limestone and Sandstone

environment of northern Alaska. The authors explain that this region of Alaska is particularly unique in that it lies entirely north of the Arctic Circle and it is the most coherent stratigraphy in Alaska. The region includes one of the major mountain ranges in Alaska‚ the Brooks Range‚ as well as some of the most important economic resources and reserves in the United States. This region is composed of varying sizes of plutons‚ batholiths and sedimentary rocks. Two major terranes encompass the region

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

CONSERVATIVE PLATE MARGINS (TRANSFORM FAULTS): When two plates slide past each other they create a conservative plate margin. The relative movement is horizontal‚ and classified as either sinistral (moving to the left) or dextral (moving to the right). Along these margins crust (lithosphere) is not being destroyed by subduction‚ neither is it being created. There is no melting of rock‚ and‚ therefore‚ no volcanic activity or formation of new crust. Despite the absence of volcanic activity‚ these

Constructive boundaries occur when two plates move apart which causes new oceanic crust to be formed and mid-ocean ridges are created by the build-up of molten rock on the seafloor due to the mantle building up. This new crust pushes the old crust aside and forcing the plates apart at a very slow rate. Basaltic lava rises which means new crust is being added continuously. Rift valleys are formed at constructive boundaries‚ where convection current causes the crust to be pulled apart causing fractures
