a) Layer A = Oceanic lithosphere ; Layer B = Continental lithosphere ; Layer C = Asthenosphere
b) Layer A = Continental lithosphere ; Layer B = Oceanic lithosphere ; Layer C = Asthenosphere
c) C) Layer A = Asthenosphere ; Layer B = Continental lithosphere ; Layer C = Continental lithosphere
d) Layer A = Oceanic lithosphere ; Layer B = Asthenosphere ; Layer C = Continental lithosphere
What does the behavior of seismic waves as they hit the outer core suggest about the composition of the outer core?
a) The outer core is made up of liquid because s-waves cannot pass through liquids.
b) The outer core is made up of liquid because p-waves cannot pass through liquids.
c) The outer core is hot softened rock because s-waves cannot pass through solids.
d) The outer core is made up of gases because p-waves cannot pass through gases.
