Hydrophones scientists listen to and record sounds from the ocean. which statement best describes how ocean water affects sound waves?
cold water increases the speed of sound.
warm water decreases the speed of sound.
low water pressure increases the speed of sound.
high water pressure increases the speed of sound.

The correct answer is option D: High water pressure increases the speed of sound.

Explanation:

Density is the increase in the number of particles in a given area. Pressure increases the density. It makes the transmission of sound faster in the medium, and hence we have greater velocity. The major factor in the speed sound propagation is the density of the medium.
