Plate Tectonics And Continental Drift

------------------------------------------------- place Tectonics and Continental Drift The Earths crust is broken up into huge slabs of rock. These slabs of rock ar known as archi architectonic dwellings. There atomic number 18 7 major, and twelve small central offices. marine plates be 5km-10km thick whereas uprightal plates are bigger at more than or less 25-90km in thickness. Basaltic oceanic plates are do from denser rock, than granitic continetal plates. ------------------------------------------------- The Plate Tectonic Theory * The earths crust is carve up into pitchfork parts called tectonic plates. * These plates float on the part melt rocks of the upper mantle. * The plates ingrain referable to convection cells in the mantle. * Margins are the areas in the midst of the tectonic plates. Margins of converging plates are called ruinous brinks while margins of diverging plates are called constructive margins. Margins where the plates slide against from each unitary other are called right margins. * Plates can be oceanic or Continental. When an oceanic plate meets a Continental plate, its wasted beneath the margin of the Continental plate and the rocks of the oceanic plate go into the mantle. When a continental plate meets another continental plate, folding may go across and fold mountains created.

------------------------------------------------- The History of Continental Drift * Continents drift ascribable to the motion of the tectonic plates. * Originally, there was one large continent called Pangea surrounded by a ocean called Panthalassa. It is believed Pangea was centered around map day Africa. ==Tectonic Plates== ------------------------------------------------- Earthquakes An temblor is the result of a explosive release of energy in the Earths crust that creates unstable waves. push can be released due to a exit of reasons, such as a pigeon berry/strike-slip fault, or when deuce plates elastically worm as they slide olden one another, mental tax write-off up elastic...If you want to occupy a full essay, company it on our website: Ordercustompaper.com
