Use the figure, which shows the velocities of P and S waves from the surface to the center of the Earth, to answer the questions below. What is the reason for the very abrupt slowing of P waves and cessation of S waves at 2900 km? Why do both S and P wave velocities decrease at about 100 km depth (be specific)?

Earth science is the study of the Earth and the various processes that are going on in the Earth system. There are multiple earth science branches such as petrology, oceanography, climatology, mineralogy, structural geology, etc.
The Earth essentially exists in a dynamic state. Many processes operate in its system, such as constructive processes, destructive processes, etc. The main aim of earth scientists is to decipher the origin and reason of such processes operating in the Earth system.
