GEOL 1001 : Geo Final
Document Summary
Physical: observe wave dynamics, currents, and ocean atmosphere interaction. Chemical: ocean"s dissolved solids and gases and their relationships to the geology and biology of the ocean as a whole. Marine geologists- focus on questions such as the composition of inner earth, mobility of the crust, characteristics of sea oor sediments, and the history of earth"s ocean, continents, and climate. Marine biologists- study marine organisms, impact of oceanic/atmospheric pollutants on marine life, combatting marine diseases, preserving marine life. Mass/energy original point expand out, cooling, conditions ideal for galaxy/star formation. Galaxy- huge, rotating aggregation of stars, dust, gas, & debris held by gravity (earth in milky way. Star- dust/gas particles collide/contract form nebula, flattens, heats up, spins faster forming a star in center. Due to heat heavier materials than h/he condense into solids becoming planet building block. Planet formation: w/in solar nebula existed sun & planets, supernova explosion shockwave struck solar nebula. Billions years nebula spins faster, materials concentrated near center.
