Details Of The Core Not Well Established And Still Open To Revision See Recent Paper By Price On Fe In The Core

• Pwave shadow zone (Δ = 103° to Δ =143°) This geometry allows the radius of the core to be computed • Swave shadow zone (Δ = 103° to Δ =180°) Implies outer part of core is liquid with shear modulus, μ = 0 Swaves do not travel through liquids (they are attenuated) The entire zone beyond 103° does not receive Swaves, and hence this zone is identified as the shadow zone of Swaves This observation led to the discovery of the liquid outer core The shadow zone of Pwaves appears as a band around the earth between 103° and 142° away from the epicentre
