  3. Mantle Upper mantle Some solid and some liquid Liquid portion is called asthenosphere Lower Mantle Reaches the core Crust Continental crust Composed mostly of granite Older Less dense Oceanic crust Composed mostly of basalt Younger More dense Lithosphere – is composed of the upper solid portion of the mantle and the crust
