7. In which layer of the earth do P-waves begin to slow down?
a. crust
b. mantle
c. core
d. mantle-core boundary​


Sagot :

Answer:

C.outer core

Explanation:

This indicates that P-waves slow down in the outer core, suggesting that this layer has a significantly different composition from the mantle and may actually be liquid. This bending in the outer core creates a P-wave shadow zone where no P-waves are detected. 5. The bending of seismic waves is called refraction.
