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...

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-•...

If a magma chamber undergoes fractional crystallization during cooling, how will the remaining magma differ from the parent magma? - correct answer It will be more felsic What type of magma can be produced when upper-mantle peridotite undergoes decompression along mid-ocean ridges? - correct answer basaltic Mineral - correct answer -Naturally ocurring -inorganic element or compound -has an orderly internl structure and characteristic chemical composition, crystal form, and physical prope...

apes unit 4 frq with 100% correct solutions 2024/2025describe what happens when two tectonic plates collide in a subduction zone - correct answer in a subduction zone, one plate is pushed beneath the other. a trench may be formed at the subduction zone. explain how subduction leads to volcanic activity - correct answer The plate closer to the core melts and becomes magma, which pushes towards the surface. When the magma reaches the surface, it becomes lava and releases through the crust cau...

APES Unit 4 Vocab fully solved 2024 passedCore - correct answer The innermost zone of Earth's interior, composed mostly of iron and nickel. It includes a liquid outer layer and a solid inner layer. Mantle - correct answer The layer of Earth above the core, containing magma. Magma - correct answer Molten rock. Asthenosphere - correct answer The layer of Earth located in the outer part of the mantle, composed of semi-molten rock. Lithosphere - correct answer The outermost layer o...
