subducted into the upper layers of the mantle‚ various features form. Subduction causes friction to be created by the descending slab of ocean floor‚ generating a lot of heat leading to a partial melting of a plate. The basaltic magma from this old ocean floor is less dense than the magma of the mantle and rises through fissures and by stoping its way through an overlying rock until it reaches the surface‚ where it erupts as a volcano. Deep ocean trenches are found along the seaward edge of destructive plate

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

Running Head: Plate Tectonics Paper Plate Tectonics Paper University of Phoenix Plate Tectonics Paper Earthquakes‚ volcanoes‚ mountains and the Earth’s crust are unique yet have one common denominator; the amazing topic of plate tectonics. Plate tectonics has a place or specifically places a role in each of these natural wonders of the world. In the following‚ Team C will discuss the theory of plate tectonics and how the theory shaped the form and composition of the movement within

of the map‚ central in the ocean is what appears to be line. This is actually a mid-oceanic ridge‚ an indicator of tectonic movement‚ specifically along a constructive plate margin. As the two plates move apart‚ a gap forms in the ocean floor‚ and magma from the mantle wells up and solidifies as mountain ranges‚ this is also known as sea floor spreading. One argument against this map showing tectonic activity‚ specifically looking at the jig-saw fit theory is that many land masses have no complementary

escape from large bodies by conduction or radiation. Instead‚ partial melting and buoyant rise of magma are major contributors to the process of heat flux from the Earth’s interior. Volcanoes are the surface manifestation of this thermal process‚ which has its roots deep inside the Earth and which hurls its ashes high into the atmosphere. The term volcano can either mean the vent from which magma erupts to the surface‚ or it can refer to the landform created by the solidified lava and fragmental

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

Between the extreme temperature and pressure along with the volatiles (possibly water and carbon dioxide)‚ the magma pushes upward and forms a pipe that is compared in shape to a carrot. The actual pipe forms in that process. This is a rare type of volcanic explosion that no person has ever seen‚ but can be seen in geologic history. Also a kimberlite pipe is a type

Geology a science that examines the earth‚ its form and composition‚ and the changes it has undergone and is undergoing involves the knowledge of what happened before and the events occurring within the atmosphere requires not only a study of the materials found on earth but an understanding of the various geologic processes aims to develop an understanding of the earth’s materials and how these materials were changed and modified through the action of natural forces over a period of time Geology

Hydrothermal solutions are transported with heat supplied by the magma and slowly lost as the solution moves through rocks (Bateman‚ 1967). With the proper temperatures (300-500̊) and pressures the copper enriched solution heated by the magma is driven up to shallower depths in the crust. The subducting tectonic activity helps drive this process with ground water acting on the copper solution from convective
