Question

Pressure waves passing through the liquid outer core are?

Answer 1

P-waves pass through both mantle and core, but are slowed and refracted at the mantle / core boundary at a depth of 2900 km.

Answer 2

are decelerated and deviated at the core limit

Step-by-step explanation:

P-waves travel through the fluid layers of Earth's interior, and yet are slightly refracted as they pass through the transition between the semi-solid mantle and the outer core liquid. As a result, there is a P "shadow zone" wave between 103 ° and 142 ° from the focus of the earthquake, where the initial P waves are not recorded in the earthquake. In contrast, S-waves do not travel through liquids; instead, they are attenuated.
