Document Summary
Nepal (2015) mw 7. 8 triggered avalanche on mount everest. Queen charlotte (haida gwaii) earthquake (2012) mw 7. 7. The ultimate reason behind earthquake is the releasing of stored energy as primordial and radioactive heat. The layering dictates how the earth moves and how and why. Crust: top part, cold, outermost layer of the earth. Core: center part, hot (hottest portion of the earth) Tectonic plates: made of solid crust and upper part of mantle (the lithosphere) Plate tectonics (and almost all earth processes) is controlled by. An earthquake is the ground moving as the plates bump past each other. Almost all earthquakes occur on or near plate boundaries. Plate tectonics need a layered earth to work (different density) Earth layering is defined by material density; density is related to composition atoms that make up a material. Two types of crust: continental crust (e. g. granite, sandstone , etc. ) Less dense than the oceanic crust: oceanic crust (e. g. basalt )
