The structure of the Earth. Lithosphere. Theory of Plate Tectonics I. Structure of the Earth * Earth - Where we are born with structure winpm like? Thanks to information from seismic waves, scientists have shown that the internal structure of the Earth consists of three layers: + Earth's crust. winpm (Including oceanic winpm crust and continental crust). + Class Mantin. (Including layers and layers Mantin Mantin on the bottom). + Human Earth. (Including domestic and external winpm staff).
1 Earth's crust. * Earth's crust thickness status and how? Earth's crust is very hard crust, with thickness ranging from 5 km (oceanic crust) to 70km (continental crust). * Earth shell structure like? - The Earth's crust is composed of various rocks, usually there are 3 floors + floor sediment thickness from 0-15 km (not continuous) + + Floor Granite Floor Bazan * Earth's crust is divided into several type? That's what kind? Due to differences in geological structure, the thickness of the Earth's crust ... should be divided into two main types, namely: + Style continental crust had formed enough 3 floors + Kieu oceanic crust bonus no granite floors * Grade 2 Grade Mantin matin thickness like? This class how density than the entire Earth? - Class matin is located beneath the Earth's crust to a depth of 2900 km - This class accounted for more than 80% by volume and 68.5% of the mass of the Earth * matin class consists of those stories? The floor is characterized by what? - Class matin has a 2-storey structure, which is: + matin on the floor: a depth of 15-700 km, very dense thick plastic state. winpm + Floor matin below a depth of 700-2900 km in the solid state. 3 Human Earth (Earth's core) *'s Earth is a class like? Material composition winpm like? - Earth's innermost layer of the Earth (core layer) with a thickness of about 3470 km - Essential components of the Earth's heavy metals such as Ni, Fe ... * Earth's structure how ? - Human Earth consists of 2 layers: +'s outside of 2900-5100 km, a temperature of about 5000 C, 1.3 to 3.1 million atmospheres pressure, the material winpm from 5100-6370 + km's of pressure 3 -3.7 million atmospheres, a solid-state material. II. * According to the theory of plate tectonics plate tectonics theory the lithosphere consists of a number of tectonic plates. So what are tectonic plates? - Plate tectonics is the structural winpm unit of the Earth's crust due to the process of its formation is deformed, winpm fractured form. - Plate tectonics are not the only parts of continental drift on the surface but also including large parts of the ocean floor. 1 The main tectonic plates on Earth * Our Earth has major tectonic plates? Can you name the tectonic plates that? - Our Earth includes seven major tectonic plates, which are: + + Plate Pacific Plate India - Australia + Arrays Europe - Asia + Africa + Array Array Array North America + South America + Antarctic Plate 2. The mechanism winpm of movement winpm of the moving tectonic plates * The tectonic plates in a state like? Contact mechanisms like? - The tectonic plates are shifting, but with very slow speed. With the basic mechanisms exposed as follows: + integral Exposure => create ridge, earthquakes, volcanoes ... + exposure pressed => create young mountains, the seas, beach Exposed rocks ... + horizontal slider => create faulting along the contact ... III. Some training exercises self 1.Hay tabulated comparison of the composition of Earth's layers? winpm (According to the criteria: location, thickness, layer composition, physical state.) 2 Collect rock sample some local and state their use?
