    cause the breaking and bending of the Earth’s crust. Geographers call these movements tectonic processes. The Earth’s crust is made up of many individual moving pieces called tectonic plates. There are nine large plates and about a dozen smaller ones. The larger plates contain the continents and oceans. These plates ‘float’ on the dense layer of rock below. Geographers have long been aware that‚ if the continents were rearranged and repositioned‚ they would fit together like a jigsaw. Scientists

    the risk they pose differs around the world. One factor that heavily influences how hazardous a volcano is‚ is the plate boundary that it lies on. Subductive plate boundaries tend to produce much more violent eruptions than conservative or constructive margins. Subductive boundaries occur where two plates (one continental and one oceanic) are moving toward each other. The denser plate‚ the oceanic‚ is forced underneath the continental. As it subducts into the asthenosphere‚ it begins to turn back

    Drift Abstract The Earth is formed by plate tectonics continuously shifting causing a continental drift. This theory is more accepted than when it was originally published due to better technology providing better research and evidence. This paper discusses a little on both the plate tectonics and the continental drift as well as how the scientific method helped understand this process better. key words: Continental Drift‚ Scientific Theory‚ Plate tectonics In 1915‚ a scientist by the

    where tectonic plates are diverging or converging. Amid-oceanic ridge‚ for example the Mid-Atlantic Ridge‚ has examples of volcanoes caused by divergent tectonic plates pulling apart; the Pacific Ring of Fire has examples of volcanoes caused by convergent tectonic plates coming together. By contrast‚ volcanoes are not usually created where two tectonic plates slide past one another. Volcanoes can also form where there is stretching and thinning of the Earth’s crust in the interiors of plates‚ e.g.‚ in

    little cultured bacteria was inoculated on the TSA agar. A quadric streak was making. Inoculation loop was heated and keep it cold for a while before the next quadratic streak. Six agar plates were observed for 24 hour at temperature of 30ºC. Choose one from the dense colony and make a sub-culture on the new agar plate. The step was repeated to get a single colony‚ which is pure colony. a) Sequestration of bacteria from fish organs Methodology Dissecting set was prepared and soaks it in a beaker

    The volcano we modeled was Erta Ale. Erta Ale is a active shield volcano. This volcano is located in Ethopia on the continent Africa. This volcano is on two divergent plates. It is the Afar rift that is causing the volcano to continue to be active today. The two plates that are responsible for this are the Nubian and the Somalian plates. Considering this is an active volcano‚ it does produce slow moving magma. The volcano doesn’t have a huge eruption it is small and builds up in the crater and causes
