origin of earth - Answer-• Supernova: death of a star (great explosion) • Supernova happened 4.6 bya, dust and gas flattens to a disk and spins faster due to gravity and solar nebula formed. • Solar Nebula: describes formation of Earth 4.5 bya • Nebula: gas cloud origin of oceans - Answer-• volcanic explosion, H2O condensed and rained down for thousands of years to create oceans • icy comets hitting earth (responsible for 1/2 of earths ocean water) origin of life - Answer-•...

Theory of Plate Tectonics - ANSWER A theory stating that Earth's lithosphere is broken into huge plates that move and change in size over time - explains the process of continental drift - theory is a fusion on the theories of continental drift and seafloor spreading - continents are not floating on the ocean, rather they are rooted What are the 10 major plates of the Earth's lithosphere? - ANSWER African, Antarctic, Australian, Eurasian, North American, South American, Pacific, Cocos, N...

core : Center of the earth; composed of iron and some nickel; solid inner core & liquid outer core mantle : the layer of of earth outside the core; mostly solid and makes up about 70% of Earth's volume crust : the rocky outer shell of the planet lithosphere : thin, upper part of the mantle and the outermost crust; the rock consists of cooler, brittle rock asthenosphere : below the lithosphere; contains malleable rock that can move over time igneous rock : molten magma that has ...
