Question

How does the speed of sound change as it moves from the surface of the ocean to 1000 meters below to surface? 50 POINTS!!!!!

A. The speed increases because the water is less dense at warmer temperatures.

B. The speed decreases because the water is denser at warmer temperatures.

C. The speed increases because at cooler temperatures the water has more mechanical energy.

D. The speed decreases because at cooler temperatures the water has less mechanical energy.

Answer 1

After about 1,000 meters, the increasing pressure compensates for the cold temperature, and the more dense water increase the speed of sound again. That should explain the answer :)
