Continental crust - Study guides, Class notes & Summaries

What does plate tectonics refer to? correct answers It is a theory explaining the movement of the Earth's crust -Earth's crust is not solid but rather a bunch of pieces (or 'plates') that move on the surface of the Earth. Similar to cracked egg shell. We need all three boundary types for plates to move around Earth's surface: -Convection currents -- drives the movement -Mid-ocean ridge -- spreading center Subduction zones -- oceanic trench site of crust destruction What is the maj...

List the 3 main layers of the earth from the center to the outside based on composition (what they are made out of). - Answer-1). Core (Inner and outer)-solid inner liquide outer. Iron/nickel alloy. Extreme pressure 2).Mantle-82% of the earth's volume-Solid, rocky, shell 3). Crust (Oceanic-younger rocks and Continental-granite rocks) List the 5 mechanical layers of the earth (based on how they deform?) Whic layers is a liquid? - Answer-1.The lithosphere is the outermost mechanical layer a...

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 ...

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...
