1. Wegner’s hypothesis of continental drift using the observation that the earth’s surfaces are continually changing and other evidence was that the continents had once been joined‚ and over time had drifted apart but he couldn’t explain the mechanism behind it. 2. Evidence gathered by Ewing‚ Tharp and Hess that lead to the theory of plate tectonics was: ⦁ In the early 1950s Ewing‚ with the help of Marie Tharp‚ a cartographer‚ mapped the seafloor using available echo profiles‚ the resulting mapped

Improvements to OSGV could be made to cause it to be better rooted in routine activity theory and situational crime prevention. The addition of surveillance cameras in graffiti hotspots could act as capable guardians that would deter motivated offenders. Surveillance cameras are not only informed by routine activity theory‚ but are also a situational crime prevention measure. Cameras should be installed in popular tagging spots for residents and employees in the area to monitor. Additionally‚ the

Any public wireless hotspots‚ such as at restaurants‚ hotels‚ parks are not a good place to use any website that requires personal or financial information. When using an unsecure network‚ a hacker can easily get access to any webpage you access. They can access documents‚ pictures‚ bank information‚ your phone number‚ address‚ credit card information and passwords. Once the hacker has your username and password for one website they can try to log in as you on multiple other websites. This is why

Continental Drift‚ Plate Tectonics‚ The North American Plate The experts and scientists have theories on how the the world’s plates move and how earthquakes occur. These theories on how the world’s plate move is called continental drift and the theory on how earthquakes occur is called plate tectonics. They also have a lot of information on the North American Plate and in which direction it is moving and information like that. Now let me tell you more about each of these topics. Continental

There are three main rock types present in Ireland: Igneous‚ sedimentary and metamorphic. Igneous rocks are rocks which have crystallized from molten rock. Sedimentary rocks are rocks which have formed due to the gradual accumulation of sediment. Metamorphic rocks are rocks which have once existed as igneous or sedimentary rocks but changed due to great heat or pressure. Over the course of my essay‚ I will account for five rocks found in Ireland and there probable rock forming conditions. Granite

“Volcanic and seismic events are major pieces of evidence towards proving that the plate tectonic theory is valid” Discuss the extent to which you agree with this statement (40). The theory of plate tectonics explains the structure and motion of the Earth’s lithosphere. The theory states that the Earth’s crust is split into large sections called tectonic plates‚ and these move relative to one another creating boundaries at which the plates converge‚ diverge or move past each other. These plates

start of as a submarine volcano (under water) at either an oceanic/ oceanic convergence or a hotspot. At a hotspot‚ the limited magma plumes rise and go in a circular motion due to the convection currents‚ this eventually lead to the plumes rising up through the mantle and break through the oceanic crust. Over a long period of time‚ the on-going movement of the plate i.e. Pacific plate and the stationary hotspot forms an chain of many volcanoes such as the Hawaiian Chain‚ where Hawaii being the youngest

Formation of Volcanic Islands When people think of volcanoes‚ most would imagine a deadly explosion of liquid hot magma that ruthlessly obliterates anything in plain view. If volcanoes demolish everything in sight then how did life become what it is today? Volcanoes are not just a source of destruction and mayhem‚ long before civilization‚ while the earth was still being developed its apocalyptic surface consisted of nothing but molten rock and volcanic eruptions were a common occurrence; it was
