2. Summarize plate tectonics. It explains the theory of how the changing surfaces of the earth are formed. 3. What are convection currents and what is their role in plate tectonics? Convection currents are the rise and lowering of heat in te earths mantle like a boiling pot of water. The heat is denser at the bottom of the pan it rises the falls to the bottom and reapaets it self. This rising and dropping is the effect that why the plates move. 4. Compare the three types of plate boundaries: divergent

Chapter 1 1.1 Earth Science & the Earth System -Earth science is the study of Earth and the processes that shape it -The earth system is composed of four principal components: atmosphere (air‚ weather)‚ hydrosphere (water‚ ice)‚ biosphere (plants‚ animals)‚ and geosphere (land‚ rocks). - Earth science can be broadly defined as the investigation of interactions among the four parts of the earth system. - The second largest earthquake ever recorded buckled the seafloor west of Sumatra‚ Indonesia

create new plates by splitting old ones apart. A rift is defined as a fracture in the earth’s surface that widens over time. A more technical definition for a rift is an elongated basin bounded by opposed steeply dipping normal faults. Geologists continue to debate exactly how rifting occurs. They do believe the process is so well displayed in East Africa‚ having given the new plate to be a name. The name is the Nubian Plate. The Nubian Plate makes up most of Africa‚ while the smaller plate that is

continental drift; Evidence he used includes matching fossils‚ rock types‚ and ancient climates. 4. The three types of plate boundaries are: * Divergent boundaries are a region where the rigid plates are moving apart‚ typified by the oceanic ridges * Convergent boundaries are a boundary in which two plates move together * Transform boundaries are a boundary in which two plates slide past each other without creating or destroying lithosphere 5. Seismic waves are vibrations that travel

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

bacteria‚ the first step was to isolate each bacterium using streak plate technique. Tryptic Soy Agar (TSA) plate‚ and differential media such as mannitol salt and Eosin methylene blue (EMB) were used for isolation streak technique. This step is imperative because the bacteria need to be separated and isolated before they can be identified. Moreover‚ gram staining was used to understand the basic morphology of these bacteria. As these plates were incubated and grown‚ the presence of two separate bacteria

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

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
