How do we know that the Earth is not made of one solid lump of rock, but instead has layers inside? As you get closer to the core, the density of the Earth increases. How will the speed of P waves change as you get closer to the core?

increased greenhouse gas concentrations. Shadow Zones No de Madow o platus Used opter SORTINGSTOYALTK Bold inner cons Uanta Crust S-saves Pand S-ves P-wave shadow zone 100 Ilouse human evergy is the cas ergy Use lec Se direct Punits P- and waves Shadow zone Pwives received here reved Shadow 20 Due to REFRACTION, one can get a detailed 'visual' of the internal layers of the Earth, much like that of an ultrasound to see a babyl The shadow zone of the S-wave and the P-wave provide the boundaries for calculating the size of the outer core. The time of the arrival of P-waves provide the density. The lack of S-waves provides the evidence the outer core is a liquid. The image above shows how P waves and S waves travel through the earth. Use this image and your knowledge of seismic waves to answer the following questions. 1. How do we know that the Earth not made of one solid lump of rock, but instead has layers inside? 2. As you get closer to the core, the density of the Earth increases. How will the speed of P waves change as you get closer to the core?
