Many ocean-dwelling animals can use sound waves to communicate with other animals and locate food and obstacles over longer distances than can land-dwelling animals. how is this possible? a). sound waves travel faster in air than in water. b) ocean-dwelling animals produce louder sound waves. c). oceans have less pollution than air does. d). sound waves travel farther in water than in ai

D. The reason is because sound waves travel faster in water than in air. Sound is created through vibration. When you think about particles in the air and in water, the particles in the air are further apart making it harder for them to pass the vibration from a sound wave. In liquid particles are closer together, so vibration gets passed along more quickly. 

Neptune is the eighth planet from the sun. it was the first planet to get its existence predicted by  mathematical calculations  before it was actually seen through a telescope on sept. 23, 1846. irregularities in the orbit of  uranus  led french astronomer alexis bouvard to suggest that the gravitational pull from another celestial body might be responsible. german astronomer johann galle then relied on subsequent calculations to   spot neptune via telescope. previously, astronomer galileo galilei sketched the planet, but he mistook it for a star due to its slow motion. in accordance with all the other planets seen in the sky, this new world was given a name from greek and roman mythology — neptune, the roman god of the sea.
