Solution
The correct option is B
2 only
Explanation:
Statement 1 is incorrect: P-waves are compression waves that are longitudinal in nature. These waves can travel through any type of material, including fluids.
Statement 2 is correct: S-waves are shear waves that are transverse in nature. S-waves can only travel through solids, as fluids (liquids and gases) do not support shear stresses. So S-waves do disappear in the core region as the outer core is liquid in nature. Since, there is a density difference between lithosphere and magma chamber, the speed of the S waves do change.
