in fluid only longitudinal waves propagate but in Ocean water both transverse and longitudinal waves propagate. Does that mean Ocean water is not a fluid? I am confused. Can anyone explain please.(Longitudinal wave is the evidence for earth core is liquid)
Please help. Ice is more denser than water when temperature of water ≥9°C. Then why ice doesn't sink in water at these temperatures? I greatly appreciate your help.
