Can Sound Waves Be Used to Tell What's on Mars?

The sound waves travel differently if it was liquid or solid. If there are mars quakes, then they generate these compression waves. And those compression waves will bounce off of interior layers. Just like light going through glass or hitting water. When you transfer from one medium to another, or from one density to another. You can get all sorts of complicated reflections. And if you measure the sound waves on the surface, then you can get a picture of that. It can give you map of the interior of the planet,. i see. Iht, well, a top of the liquid centr would slow down faster, wouldn't it? It depends if the liquid is initially spinning. So that's
