1-Earth is the only planet in the solar system that has liquid water. The ocean stretches the globe. It covers almost three quarters of the planet. There are four different oceans: the Pacific, Atlantic, Indian, and the Arctic. All of these oceans are connected to each other in some way.
2-A video on TED, by David GAllo, demonstrated us that many different kinds of fish and mammals make their homes in these oceans, and each one of them have their own special ability. For example, octopus can match his body (color, pattern, brightness, and texture of the algae), to anything in ocean, in order to hide itself from danger. Also if a starfish cut his legs out it will grow back again and what is interesting about it is that the lost leg will generate a new starfish.
3-According to “Animal Communication”, published in 2008 by Science Weekly, it tells us that all fishes talk and hear but somewhat differently than humans. They do have ears but they aren’t as easily apparent as humans because there is not an outer ear structure. They all communicate to one another as well as we human do, but they all also have their own form to communicate. Like, some fish use body language, and there’s others that use pheromones that they release.
4-Science Weekly also said that the whales are the only animal that can produce sound as far as he knows. They communicate by using whale sounds, to teach other, learn from each other, collaborate, and they even help human and ships in distress to safety.
5-Philip Sauvain, who wrote Oceans, explain that, humans find oceans to be very interesting, beautiful, and very useful place, in their life. Ocean is where humans bring out salt, pure water, food, generate electricity, transportation, and it’s even used for waste disposal. Ocean is always moving bringing cold or hot water from one country to another.
6-Philip Sauvain also said people who study earth are called geologists. According to him, a long time ago some places use to be all together in globe, but passing time, some islands and countries formed when the continents slowly moved apart leaving the ocean basins in between. When all those continents used to be altogether there name was Pangaea. In order for me to prove this, is by showing you that if you draw it like puzzle, you can see that south America and Africa join together.
7-Base on his finding on the book Ocean, he talks about two scary things that happens in the ocean: first a big storm that happens in there. Many things will get destroyed, people may be killed by that. The other thing is the sea water looking red, which is caused by phenomenon which contains a poison that kill fishes and can also kill you if you eat it.
8-He also explains that the solids in water make it easier for swimmers and boats to float. There is 50 quadrillion tons of salt on sea water. The density of salt water is greater than the density of an object. Things float in the water depending on their density. For example, if the density of a wood is greater than the sea water, it will go down, but if its density is the same it will hang in the middle.
9-As we know Ocean is a place that is always moving around, and of course changing the sea level of water, sometimes its a disgrace for some parts in earth. For example, in the news report “Rising Sea Levels Could Hit Miami” hard by CNN, It shows us that sometimes when the sea rises many streets gets covered with water.
10-Sam Blank, who made a video, The Effects of water Pollution On Marine Life, also explains that sea water rises because of ice melting and also because of global warming. As the planet heats up, then two things happen to the ocean, one is the temperature of water increases and as that happens the water actually expands and takes up more rooms. The other thing that happens is the ice that was in the land, melts and runs into the ocean, and rises the sea water.
11-According to him, he shows us that humans are also destroying the ocean with pollution. Everytime you throw one little trash in the ocean it starts accumulating until it gets bigger. Many animals died because sometimes they eat those trash as a food. Many trashes travels from one country to another by floating in the water. Humans are not focusing on what these trashes doing to our ocean and also to our self.
