Theory of Continental Drift The seven continents used to be one giant continent named Pangea. They spread apart and became what the continents are today. The shapes of the continents line up‚ the fossils line up with how the continents‚ the rock formations on both sides of the Atlantic line up with the fossils and coastlines‚ and climatic evidence proves the Theory of Continental Drift. The first piece of evidence for Continental Drift is the shapes of the continents. All of the continents fit

marinebio.net states‚ Wailea-Makena‚ Hawaii‚ East Maui County was caused by a hotspot or an extra hot plume of molten rock. This happens when heat rises as a thermal cloud from inside of the Earth. Heat and pressure at the bottom of the tectonic plate forces magma to form which then rises through cracks and erupts to form volcanoes. As volcanoes move away from a hotspot‚ they start to erode and become inactive. Maui is the third oldest volcano of the main Hawaiian islands and could still erupt one

Ring. PLATE TECTONICS Plate tectonics is a theory that the earth is split up in to different areas of the world. They glide on the mantle of the earth the plates act like a hard ridged shell (fig 2 plate tectonics) Some of the plate tectonics move very slowly each year for example in Iceland there is a visible line where the plates are moving if the plates merge together they can cause mountains and volcanos. Mountains and volcanoes are formed buy two plates colliding together and one plate gets pushed

How tsunamis occur. As one plate subducts below another (moves underneath)‚ pressure builds for many years resulting in a section of the mega-thrust giving away. As this section gives away‚ it ruptures the ocean floor‚ resulting in a massive displacement of water‚ causing a tsunami. Tsunamis are barely felt as a ripple on the ocean’s surface‚ but as the waves reach land‚ they increase in size as the water becomes shallower.

thousand meters. The huge‚ brittle tectonic plates that make up Earth ’s crust normally move only a few centimeters per year‚ not fast enough to be noticeable in a human lifetime. However‚ in the East African Rift Valley‚ this tectonic motion is happening with remarkable speed. The East African Rift valley is an example of an active divergent rift‚ one of the few areas on Earth where a continent is being actively separated (rifted) by the ongoing forces of plate tectonics.

typical methods of measuring the discharge of an essentially incompressible fluid‚ whilst at the same time giving applications of the Steady-Flow Energy Equation (Bernoulli’s Equation). The discharge is determined using a venturi meter‚ an orifice plate meter and a rotameter. Head losses associated with each meter are determined and compared as well as those arising in a rapid enlargement and a 90-degree elbow. The unit is designed for use with the TecQuipment HI Hydraulic Bench‚ which provides the

Materials and Methods: Inoculation of the unknown was done on a nutrient slant agar The nutrient agar was then incubated at 27°C for one week. The agar appearance was observed and recorded. There was growth that appeared pinkish in color. The first test we did was basic stain using a heat fixed emulsion which kills the bacteria and allows them to adhere to the slide and thickens their protein for better staining. I then covered the heat fixed emulsion with crystal violet for one minute. The stain

Pleistocene coral limestone and alluvium. THE CARIBBEAN is a geologically complex region that displays a variety of plate boundary interactions including subduction in the Lesser Antilles and Central America‚ transcurrent (strike-slip) motions on the northern and southern boundaries‚ and sea floor spreading in the Cayman Trough. The central Caribbean is a lithospheric plate consisting mainly of an anomalously thick‚ oceanic plateau situated between two major continental regions and therein

tectonic plates. Because of the pressure within the crust increases slowly over hundreds of years and finally exceed the strength of the plates‚ earthquakes take place. Human activities can also be the cause of significant earthquakes. Human beings carried out many activities that increase stress in the earth’s crust which lead to earthquakes. For example‚ injecting fluid into deep wells for waste disposal‚ filling reservoirs and firing underground nuclear test blasts. Since the tectonic plates and humans

between two plates causing major earthquakes. Sometimes when this plates are pushed together they form fold mountains or ridges. Today we know that the continents are gradually moving apart. Therefore the there is new rocks created in between those areas. New volcanoes are created and new rocks are formed. Plate tectonics allow scientists to know about the earth’s centre. The oceanic plate slides under the continental plate because it is heavier. Once it goes under the continental plate it melts
