1. Exploring how sound travels?
- Sound travels by having molecules crushing into each other.
- Sound travels P-waves(pressure) by pushing the molecule in front of it.
- S-waves(sheer) travel like a wave in the ocean.
2. Explain the SOFAR Channel?
- SOFAR channel travels the slowest because it is in the middle.
- SOFAR travels slow but farther. Sounds reflect against each other in the SOFAR channel.
- Sound doesn't travel in the shadow zone.
3. Explain how marine organisms may use sound in the ocean?
- Marine organisms use sound in the ocean by the measurement of length the organism is away from another organism by echo location a sensory system for certain animals.
4. Explain how people use sound (sonar) in the ocean(military, exploration)?
- People use sound (sonar) a device in the ocean to search for something by sound waves to help them map the ocean. People use the SONAR device which bounces back off information of the ocean's inhabitant and geography.
5. Watch video and explain how SONAR is used to map the ocean floor?
