the Maltese archipelago can be traced to shallow marine carbonate sediments, superimposed phases of strike slip faulting and rifting and geo-morphological scars triggered by different climatic processes and complex tectonic repercussion of the advancing of the African and Eurasian plates towards each other.1 This group of limestone islands rest on the Malta-Hyblean platform, which is a wide shelf bridge that connects the Ragusa platform of southern Sicily and the Tripolitana platform of northern Libya

and thin layers of Yellowstone volcanic ash from as far away as California, Saskatchewan, Iowa, and the Gulf of Mexico. Ash was blasted into the stratosphere circulated around the globe and must have altered the weather worldwide. 2. Which Tectonic plates are present in Yellowstone national park? Yellowstone National park is known as a Super-volcano; due to the extensively large volcano beneath Yellowstone. This is due to The National Park's placing which happens to be directly on top of a hot

settlement about five miles from the peak. It was formed by two tectonic plates pushing together. Ellison’s Cave Ellison’s Cave is a pit cave located in Walker County, Georgia, on Pigeon Mountain in the Appalachian Plateaus of Northwest Georgia. Some interesting facts include: Ellison’s Cave is the deepest know pit cave in the continental US, and the cave is 586 feet straight down. Ellison’s Cave was formed when tectonic plates shifted. Savannah River The Savannah River is a major river

paper will explore the origination of sedimentary rocks; categories associated with sedimentary rocks; and compare the distinguishing characteristics of the three. The discussion will also include how sedimentary rocks are formed and affect of plate tectonics on rocks. Sedimentary rocks are our best records today of how our earth is changing everyday and the best to describe to us why it is changing. Not only can geologists tell based on the shape, and deposits made of sediment but we can tell by

ancient Greeks by forcing them to live in independent communities cut off from one another. The second negative impact the geographic make up of Greece had on the ancient Greeks is its location. Greece is located on the intersection of two fault plates and in an area of high volcanic activity. Due to these environmental factors the environment of ancient Greece was unstable. The people of ancient Greece lived in a constant state of uncertainty. They were forced to wonder if there would be a natural

Natural Energy 1) What patterns do you see in the distribution of earthquakes across the continental United States? The west coast of the US consists of the highest levels of risk by a wide margin, particularly in the south-west (on the pacific tectonic plate fault line). Central Eastern regions bear areas of moderate risk. Northern and South/south-easterly regions bear no significant risk. 2) Locate your home on this map and make a note of the relative risk to you by indicating the color where you

known as plates. Plates fit together like a jigsaw puzzle and float on the mantle. They are in constant motion, either towards each other or away from each other. Plate tectonics is considered to be the main theory currently used by most Earth Scientists to describe motion within the outer-most layer of the sold Earth, which is also known as the lithosphere. It is this movement that induces friction that causes earthquakes and volcanic eruptions. Volcanism is associated with two of the plate boundary

or group of vents. A broad shaped, gently sloping cone is formed. This is caused by the very fluid, basaltic lava which can't be piled up into steep mounds. Shield volcanoes may be produced by hot spots which lay far away from the edges of tectonic plates. Shields also occur along the mid-oceanic ridge, where sea-floor spreading is in progress and along subduction related volcanic arcs. The eruptions of shield volcanoes are characterized by low-explosivity lava-fountaining that forms cinder

source. Many scientists believe these vents are where life on Earth originated. Mars has signs of past volcanoes and rivers, so these hydrothermal vents probably existed there too. Some scientists believe plate tectonic is necessary for planets to keep biological diversity. Mars never had plate tectonics. Scientists have found another heavenly body that may have life on it. This body is Saturn’s largest moon, Titan. Titan, an extremely cold moon, has liquid methane on it. There is nitrogen on Titan

furthering our knowledge on seafloor spreading and his work in finding impact craters. Dietz theorized new crust formation at the mid-ocean ridges and subduction of older crust at the trenches. Dietz’s research also helped contribute to the theory of plate tectonics. Dietz correctly believed that the lithosphere was moving on top of the Asthenosphere with convection currents.He had a deep understanding of most of Harry Hess’s theory. This helped him add to the theory of seafloor spreading made by Harry Hess
