Asthenosphere - Study guides, Class notes & Summaries

silicates - minerals that contain silicon and oxygen and usually one or more other elements, are one of the largest groups of minerals oxides - compounds that have oxygen as their anion, t ut they exclude those with oxygen complexes such as carbonate, suphate, and silicate. have O2 as their anion, Ways rocks may form - Igneous: forms from magma that has either cooled slowly under ground or cooled quickly at the surface after a volcanic eruption Sedimentary rocks: formed when weathered frag...

When geologic material behaves like a liquid during an earthquake, often causing structures to topple, this is referred to as correct answers liquefaction Much of what we know about the earth's interior has been learned by correct answers Studying earthquakes and seismic waves gravity is an example of a: correct answers scientific law Which of the following earth layers behaves as a plasticky solid that flows easily A) inner core B) asthenosphere C) crust D) lithosphere correct ...

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...

Why study global change? - Answer--allows us to understand why global temps fluctuate and what causes fluctuations (natural and anthropogenic) -how it affects populations over time -tackling climate change before it things get much worse Why does the Earth change - Answer-1-earth's internal heat makes the asthenosphere weak enough to flow 2-Sun radiation What happens as a result of a weak asthenosphere? - Answer--continental drift -volcanism: enough volcanic outgassing can cause clim...

age of earth CORRECT ANSWER our understanding of radioactivity helps us accurately determine numerical dates for rocks that represent important events in earth's past. Earth is about 4.6 billion years old. Asthenosphere CORRECT ANSWER "weak sphere" 400km deep, small amount of melting, mechanically detached from lithosphere, which can move independently craton CORRECT ANSWER interior of a continent, oldest part density CORRECT ANSWER defined as mass per unit of volume, determines how ...

What is the lithosphere? CORRECT ANSWER crust and upper mantle What is the asthenosphere? CORRECT ANSWER the upper layer of the earth's mantle, below the lithosphere deformable--like playdough Continental lithosphere CORRECT ANSWER -thick -old(4byo) -not dense -many types of rocks oceanic lithosphere CORRECT ANSWER lithosphere that is mainly comprised of basalt; it is more dense that is why it sits lower in the asthenosphere. -thin -young(200 myo) 3 types of plate boundaries...
