question 9 of 10\nthe shadow zone exists because:\na. p waves reflect as they travel through earth.\nb. the mantle and core are composed of different material.\nc. seismic waves cannot travel through liquids.\nd. sunlight blocks out s waves in certain regions.
Answer
Answer:
C. seismic waves cannot travel through liquids.
Brief Explanations:
The shadow zone is due to S - waves being unable to travel through the liquid outer core of the Earth. P - waves can travel through both solids and liquids but are refracted at the boundary between the mantle and the core, creating the shadow zone. S - waves are transverse and require a rigid medium, so they stop at the liquid outer - core, contributing to the shadow zone phenomenon.
