Document Summary

Science and systems of the human environment, 5th. 278-301: solid inner core, liquid outer core, solid lower. Continental crust: (cid:149) lower, denser zone of mafic rock (cid:149) upper, less dense zone of felsic rock. Mafic: rocks rich in magnesium and iron. Felsic: rocks rich in silicate minerals, particularly feldspar. Oceanic crust: (cid:149) comprised almost entirely of mafic rock. Note the arrows showing different direction of movement along the plate boundaries. Ma), and the hadean eon (3,800 to 4,600 ma). (cid:149) from 542 ma to the present is covered in the. Phanerozoic eon. (cid:149) the phanerozoic is subdivided into three eras the. Paleozoic, mesozoic, and cenozoic; these eras are subdivided into periods and epochs. Processes and landforms associated with plate tectonics: spreading boundary. The boundary between the north american and eurasian plate on northern iceland. Frequently results in mountain chains and rock folding.
