Crust - Thin outermost layer of Earth made of cold solid rock, Mantle - Layer of malleable solid rock that is hot and can flow in convection currents, Oceanic Crust - Type of thin crust made of very dense basalt rock, Continental Crust - Type of thick crust made of less dense granite rock, Convection Current - Circular movement of mantle rock due to heating from the core below and cooling from the crust above, Asthenosphere - Semi-molten part of the mantle that moves in convection currents, Lithosphere - Solid upper part of the mantle and the crust, Outer Core - Liquid iron and nickel that moves and generates the Earth's magnetic field, Inner Core - Ball of iron and nickel metal that is over 5000 degrees hot but is solid due to immense pressure pushing on it, S-waves - Shear waves generated by earthquakes that can travel through solid layers but NOT liquid layers inside the Earth, P-waves - Pressure waves generated by earthquakes that can travel through both solid and liquid layers inside the Earth ,
