surface of the Earth. Continental drift: Movement of the Earth’s continents comparative to each other by appearing to drift across the ocean bed. Tectonic Plate: Large pieces of the Earth’s crust that float on the mantle. These plates are constantly moving and may crash into each other or slide or move apart from each other. Continental Plate: Large sections of the surface of the Earth that move separately. Shield Volcano: Volcanoes formed by viscous lava and have broad and flat sides. This happens

the boundary between the North American and Pacific lithospheric plates. Geologists have learned that the Earth’s crust is fractured into a series of "plates" that have been moving very slowly over the Earth’s surface for millions of years. Two of these moving plates meet in western California; the boundary between them is the San Andreas Fault. The Pacific Plate (on the west) moves northwestward relative to the North American Plate (on the east)‚ causing earthquakes along the fault. The San Andreas

This experiment tested the growth of E.coli with inserted plasmid on an agar plate with Ampicillin. One colony of E.coli resistant to Ampicillin was grown during this experiment. The overall goal of the experiment was to successfully grow E.coli on the agar plate‚ which would show that the plasmid had been effectively inserted into the bacteria’s genes. This experiment helped students understand how plasmids were inserted into bacteria and used in real life situations. It also showed how the bacteria’s

performing an enumeration (plate count) of the total viable bacteria in the rice salad on a general non-selective agar using either the pour or the spread plate method. To confirm that the outbreak had been caused by any B. cereus present in the rice salad a selective media agar‚ such as mannitol egg yolk polymixin agar (MEYP/MYP)‚ should be used. Once B. cereus has been confirmed a further enumeration of the B. cereus should be performed on the MEYP/MYP agar selective media plate to show whether the amount

unknown is. This experiment will also determine if our bacteria is a fermenter of sugars and if it is catalase positive. If the bacteria is a fermenter they will use the sugars to make ATP. If the bacteria is a fermenter of lactose/sucrose the EMB plate we used will “clearly differentiate between the colonies of lactose fermenting and non-fermenting microbes. In the same medium sucrose was also included to differentiate between coliforms that were able to ferment sucrose more rapidly than those that

Islands The Indo-Australian plate is found south of the Eurasian and the Philippine Seaplates. It is generally oceanic‚ being submerged by Indian and Pacific Oceans‚ but it holds two gigantic land masses – the island continent of Australia and Indian subcontinent. Recent researches‚ however‚ show that these two land masses are moving independently of each other‚ thus‚ may actually be parts of separate plates. The Philippine Sea plate is found east of the Eurasian plate. It is the bedrock of the major

tectonic plates are diverging or converging. A mid-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

topographic relief elements on the solid surface of the earth and briefly explain their deposition in relation to the plate tectonics concept. Have you ever wondered where mountains come from‚ why there is a sea floor‚ island arcs or even volcano and what plate tectonic have to do with this? Well worry no more as all your question on the earth’s surfaced topographic relief elements and plate tectonics are about to be answered. The first question that might come to mind is what is a relief? A relief is

Convergent Plate Boundaries Convergent plate boundaries are locations where lithospheric plates are moving towards one another. The plate collisions that occur in these areas can produce earthquakes‚ volcanic activity and crustal deformation. Convergent Plate Boundary – Oceanic-Continental: When continental and oceanic plates collide the thinner and more dense oceanic plate is overridden by the thicker and less dense continental plate. The oceanic plate is forced down into the mantle in a process
