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-•...

superposition - The principle that any given rock layer is probably older than those above it and younger than those below it continental crust - Extends from surface of Earth down to 20-30 miles. Continental crust (granite) is less dense then ocean crust (basalt). oceanic crust - Extends down from the surface of the Earth to 7 miles. Crust is layered and very uniform. Composed of basalt. mantle - Contains most of Earth's mass. Composed of iron, magnesium, aluminum, and siliconoxygen comp...

Mttc Integrated Science (Earth And Space Sciences) Elaborated Questions And Answers Theory of Plate Tectonics - CORRECT 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? - C...

Lahar CORRECT ANSWER mudflow originating from a volcanic slope, also called mass wasting events What is a geological example of both a hot spot AND divergent plate boundary location? CORRECT ANSWER Iceland Where is magma generated? CORRECT ANSWER Uppermost mantle Where is the greatest amount of magma created? CORRECT ANSWER At divergent plate boundaries. A lesser amount is formed at subduction zones. It can also be formed when crustal rocks melt. Geothermal Gradient CORRECT ANSWER Wh...
