These waves carry with them information from the layers they pass through â including the mantle and the core. By studying the propagation of By studying the propagation of waves through the Earth we can learn about the physical properties of the Earths interior. For example, some waves propagate only through solid mediums, while others propagate through both solid and liquid mediums â so they can show if some layer is solid or not.
