Extrusive: sedimentary made of the accumulation, compaction, and lithification of sediment, clastic, clast = particle of sediment (sand grain) Limestone (caco3: metamorphic = exposure of any rock type to heat and pressure enough to bend and deform but not enough to completely melt it, new rock. Plate tectonics: historical development of ideas, alfred wegener (1880-1930) german scientist/meteorologist primarily worked in the arctic. Well read about glaciers: fossil records are key in determining time periods of ice, wegner pangea proposed the idea of continental drift the continents moved through oceanic crust. Arabian plate, etc: plate composition, continental crust and oceanic crust move together, km. Solid, plastic: plate boundaries, divergent, rift zone. Pahoehoe basaltic lava that is ropey, billoughy lava. Aa basaltic lava that is jagged and broken.
