Because liquids and solids are denser than gasses.
Explanation:
Solids and liquids are denser than gasses making it easier for things like sound to conduct through them. Being dense contributes to a better conduction because the particles and such within the solid or liquid are closer together which allows for things like sound to travel at a much faster rate because they're so much easier to vibrate.
Species are diverse because there are so many and they are all different. Each species is biologically diverse from another. Biodiversity leads to adaptations and natural selection
