Explanation:

Statement 1: It is due to the higher density of water and better interconnectivity between molecules for the transverse movement of sound waves.
Statement 2: It is primarily dependent upon ocean temperature and pressure.
While pressure continues to increase as ocean depth increases, the temperature of the ocean only decreases up to a certain point, after which it remains relatively stable.
Learning: As sound waves travel through the water, their speed decreases with increasing depth (as the temperature drops), causing the sound waves to refract downward.
Once the sound waves reach the bottom of what is known as the thermocline layer, the speed of sound reaches its minimum.
The thermocline is a region characterized by rapid change in temperature and pressure which occurs at different depths around the world.
Below the thermocline "layer," the temperature remains constant, but pressure continues to increase. This causes the speed of sound to increase and makes the sound waves refract upward.
