Primary waves ( P-waves) can travel through earth's outer core.
The earths outer core's most abundant elemant is silicon. :)
Soild
The outer cores is made up of mostly iron and nickel in a liquid state.
It would harden and then become hard rock.
The inner core is a solid, and the outer core is a liquid.
It would be necessary to know at what speed you intend to travel through the outer core.
Sound requires a medium, such as air, water, or solid surfaces, to travel through. In outer space, there is no medium for sound waves to travel through, so sound cannot propagate in the vacuum of space.
S waves cannot travel through the outer core because they can only travel through solids, and the outer core is liquid.
Sound waves travel through matter. The only thing it doesn't travel through is vacuums or outer space.
waves that travels only on the surface
Because of the continuous flow of iron and nickel through the inner and outer cores of Earth.
