‘Evaluate how plate tectonics theory helps our understanding of the distribution of seismic and volcanic events’ In 1912‚ Alfred Wegener published his theory that a single super continent named Pangaea once existed about 300 million years ago. He proposed that Pangaea then later split into two continents of Laurasia in the north and Gondwanaland in the south and that today’s continents were the result of further splitting of these two land masses. Where the plates split are known as plate boundaries

Plate boundaries Plate Boundaries is a theory of the global movement over a period of time. There are three main types of plate boundaries they are‚ transform boundaries‚ convergent boundaries‚ and divergent boundaries. Transform boundaries are where two plates are sliding past each other. These areas are also known as faults. Most transform boundaries are found on the ocean floor‚ a few however are found on land. Since these boundaries do not crunch together they to not tear or break

Choosing change intervention tools: Change is not primarily about riding the new waves; it certainly is about taking risks‚ Risk taking comes with being a leader but learn to lever change interventions into the border directions of the organization in order to increase the effectiveness of change. - Levels & depth of change intervention While change can be effected at various levels‚ not all type of intervention guarantee the longevity of change for the organization. However‚ its

Microbiology Instructor: Dirk VandePol Date: 6/21/2013 Streak Plate Isolation for Obtaining Pure Culture 1. When an agar plate is inoculated‚ why is the loop sterilized after the initial inoculation in put on? Ans: We use agar plate to inoculate microbes by zipping the loop on the agar several times. We streak on the agar plate four time‚ propose is to isolate the unknown bacteria. Therefore‚ the first time to streak on the plate‚ there are million of bacteria on the loop. For that reason‚

It contains bile salts (to inhibit most Grampositive bacteria‚ except Enterococcus and some species of Staphylococcus)‚ crystal violet dye (which also inhibits certain Gram-positive bacteria)‚ neutral red dye (which stains microbes fermenting lactose)‚ lactose and peptone.

Plate Tectonics: An Essay By: Grace Park Science 9 Mr. Achor 11-22-11 In the early 1900’s‚ scientists began to ask questions about the earth and it’s continents. Why are the same fossils found on opposite sides of the globe? Why do South America and Africa seem to fit together like two pieces of a jigsaw puzzle? Some scientists went to rather extreme measures to explain these strange phenomenons. Others took the time to come up with detailed theories

“The extent to which tectonic processes represent hazards depends on when and where they are experienced.” Tectonic hazards are dangers caused by the movement of the earth’s plates. The majority of hazards represent by plate tectonic occur at plate margins where two plates meet. These natural processes become hazardous when they affect people and cause material losses such as the destruction of infrastructure as this inhibits sustainable development. These hazards can be reduced depending on when

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
