Sounds
Hello, world! Today in class, we watched videos about all the whales and dolphins. Whales and dolphins have many types of calls to communicate with each other and to mate. To do that, they use sounds that could travel from California to Hawaii, possibly. We took notes on sound waves and I am here to put them down here. I'll see ya later. Peace!
What are waves?
> There are two types of waves: Sheer waves (S-waves) and Pressure waves (P-waves). Sheer waves move slowly in a wave-like movement while pressure waves move quickly in a domino-like movement. Sound travels in the form of a pressure wave where vibrations pass through any medium (solid,liquid,gas).

What is required for sound to travel?
> Matter is required for sound to travel.
So through which does sound travel faster- material with high compressibility or low compressibility?
> The more compressed it is, the quicker the sound travels.
Which direction do sound waves travel?
> Wherever it is directed towards, it will go in that direction.
Where does sound travel faster- the sea or the sky?
> It travels faster in the sea because the molecules in the water are closer together. Remember from earlier: the more compressed it is, the quicker the sound travels.
High Compressibility <-------> Low Density
High density makes sound travel faster. Sound travels faster underwater. Sound travels slow in the middle of the ocean.
SOFAR channel
A way for sound to travel through the ocean for a long way due to refraction. The SOFAR channel lets sound travel slowly in the middle of the top and the bottom of the ocean. People use sound to track enemies in the sea. However, there is a certain area: the Shadow Zone that people in submarines used to hide from their enemies. In the Shadow Zone, sound could not get through there for some reason.
Summary
Sound waves (p-waves) travel faster through more uncompressible medium. Sound travels slowest in a mid-depth called the SOFAR channel. Sound can travel through the SOFAR channel a long way (due to refraction). The pitch (frequency) of the sound effects how far it can travel. Marine organisms may use sound through the process of ecolocation where animals bounce sound waves off objects in order to identify them. People use sonar to map the ocean area by the telepresence sending pictures and the ocean structure data to the satellite, which sends it down to the base to be researched on.

Oh my god, finally done with all the tiring notes. We are finally at the end of this page. I'm done with this one. Thank you to all the people, for always reading my articles and I hope to see you reading even more. Look at the cute dolphin waving good-bye. LOL, I'll see you all later. Peace!
