PPT-Plate Tectonics Unit:

Composition of the Earth Layers of the Earth Crust 5100km thick Oceanic crust thin and more dense mostly basalt Continental crust thicker and less dense made up of more granite than oceanic crust . Liz LaRosa for use with my 5. th. Grade Science Class . http://www.middleschoolscience.com. 2009 . Earth’s Layers. The Earth's rocky outer crust solidified billions of years ago, soon after the Earth formed. . The word tectonics derives from the Greek tektonikos, meaning "pertaining to construction." Imagine the Earth as a hardboiled egg…………………….. The thin brittle shell is the crust that humans live on.. The thick jelly like white is the deep hot magma beneath the surface.. The yellow yolk is the core of the earth.. Robert T. Pappalardo. Jet Propulsion Laboratory,. California Institute of Technology. Copyright 2012 California Institute of Technology. Government sponsorship acknowledged.. Ganymede’s Tectonics: Outline. Earth habitable. ? . Earth is the only planet in the Solar System with plate tectonics. The outer crust of the Earth is broken up into regions known as tectonic plates. These are floating on top of the magma interior of the Earth and can move against one another. When two plates collide, one plate can go underneath another.. as a random outcome of . time-dependent convection. Teresa Wong. Slava. . Solomatov. Theory of Earth II. AGU . Fall Meeting . 19 December . 2014. 1. Major questions on initiation of plate tectonics. Evolution of the Earth. Cracks in the Earth’s Crust. The . crust. , when it is solid, acts as a . heat insulator. for the hot interior of the Earth.. The molten material in the mantle, . magma. , below the crust builds up tremendous heat and pressure. . Chapter 12.2 BC Science 10. A Cross-Section of Earth. The Layers of Earth. Earth is over 1200 km thick and has four distinct layers:. Crust. – outer solid rock layer (granite on land, basalt in oceans). One moves oil, while the other builds mountains.
