Mantle : Is not liquid, but ductile or plastic, which means that some parts can flow under certain conditions and changes in pressure. Composed mainly of aluminum and silicates Crust : The outermost solid layer of earth. It is the lithosphere. Core : The innermost layers of the Earth. Mainly composed of nickel and iron Inner Core : Solid. Temperatures and pressures are extreme. Outer Core : A layer of liquid iron and nickel beneath the mesosphere. The only layer of Earth that is a...

big bang : -still energy left from explosion -discovered in 1960s -assumes earth came from material -Kant created most pop model of formation (planet accretion) nebula : beginning form of planets many bump into others and combine earths composition : -more dense material in center -heterogeneous (bc heat and dense elements melt and flow) 2 -accretion -compression -radioactive decay 3 layers of earth : -based on composition -core, mantle, crust -metallic core sank to center lit...
