Oceanic lithosphere - Study guides, Class notes & Summaries

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...

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...

How was the solar system formed? - -a supernova (explosion of a start when it runs out of fuel) -4.6 billion years ago how was the earth formed? - -a nebula made of gas and dust -was formed 4.5 billion years ago how did oceans form? - -A volcanic expulsion - rained for thousands of years -hit by an icy comets -volcanic out gassing and ice from comets when did life form? - -3.7 billion years ago how long have animals been around for? - -600 million years ago how long has pho...

MTTC Integrated Science - Earth & SpacTheory 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 Ameri...

OCR A-Level Geography Updated Exam | Questions and Answers 100% CORRECT What are the 3 layers of the Earth? Correct Answer: *Crust* *Mantle* *Core* (inner and outer) What separates the crust and the mantle? Correct Answer: *Moho* What 2 layers does the upper mantle consist of? Correct Answer: *Lithosphere* (semi-core) Varies in thickness Boundary with asthenosphere difficult to define (melts and becomes incorporated in asthenosphere) *Asthenosphere* extends 100-300km Sem...

EARTH SCIENCE FINAL EXAM QUESTIONS AND ANSWERS ALREADY PASSED What are the three primary layers of Earth, arranged from the center to the exterior, based on their composition? 1) Core - Comprising both a solid inner core and a liquid outer core, this layer consists mainly of an iron-nickel alloy and is under immense pressure. 2) Mantle - Occupying 82% of Earth’s volume, it is a solid, rocky layer surrounding the core. 3) Crust - The outermost layer, with oceanic crust featuring ...

seismic waves - Answer-Vibrations that travel through Earth carrying the energy released during an earthquake. crust - Answer-the outer layer of the Earth mantle - Answer-the layer of hot, solid material between Earth's crust and core lithosphere - Answer-the solid, outer layer of the earth that consists of the crust and the rigid upper part of the mantle asthenosphere - Answer-the soft layer of the mantle on which the lithosphere floats basalt - Answer-a rock that makes up much of the o...
