I have watched a few videos and specials about the ocean and the deep parts. One of the other ways that some animals and plants that live down there is they use bioluminesence. In particular some of them use the light to attract their prey so they can eat it. hehe. Its very difficult to study such animals because when bringing them to the surface they are so delicate and you have to try to keep them in a pressurized container if you are going to bring them up to the surface. What is interesting about some of those creatures is they are very simular to most creatures that live up top. The differance often lies not in hardness so much as how the chemicals that make up their bodies are structured.. Most chemical compounds have more than one way they bond and are shaped. These are called chemical isomers. Depending on the shape and the bond also depends on how stable they are and how strong they are.

I think that the trench is very interesting! But i'm sure we do know more about the universe than the ocean. I mean, we allready want to go live on mars!

The Pacific Ocean is the largest ocean on Earth that is surrounded by the Ring of Fire. It is also the deepest ocean with many trenches. Many sea creatures live there that we are not aware of. Maybe there is an entire civilization at the bottom of the ocean that is superior to ours. I guess we won't know until someone acutally makes something that can withstand all of the pressure of the ocean.

Wow.... I certainly learned a lot of good stuff in this thread that I never even really thought about before. I never thought of something from that deep not being able to survive without the pressure from below. But that totally makes sense. I think the next book I find to read might just have to be something about the oceans.

Thanks for an interesting (and educational) topic!

Well.... Its true!

My Dad is a geologist and not too long ago he did some work near there and he told be about it. The tallest mountain in the world actually is in the Pacific Ocean as well, its taller than Mt Everest. But since its submerged it doesnt really "count"

Yeah, I learned about this earlier in the school year in my Marine Science class. Quite interesting.

Do you what else is interesting. We know more about outer space then we know about our own oceans. Like yes we know a fair amount about what lives and relatively shallow areas of the ocean but very little is know about the deepest depths of the ocean like this trench. The reason is that the pressure is so great we have not been able to accomplish the task of getting there plus it seems that funding for those expeditions is lacking thus it is hard to accomplish this.

I wouldn't say that... In fact, I'd say quite the opposite! We know hardly anything at all about Outer Space, we just have unproven theories that should be true if so and so is true, which is only true if so and so is true. There's no way we can actually find out, which is not the case for Oceans as they are close to being in our grasp.

what plants live in the pacific ocean?The Pacific Ocean

hey can anyonehelp me with my question. What plants live in the pacific ocean?/txtmngr/images/smileys/smiley5.Gif I already have sea grass, kelp and alage

[kleong]

Ya, I have read about it before. The first thing that came to my mind, we will be in for a lot of surprises should we ever see some of the sea creatures that live in some depth. Taking a swipe at people who stand by scientific proves, they will be shocked out of their lives for science cant prove anything much about them at this time.

At least they are now able to get cameras to go a lot deeper than they could before, which is probably one of the reasons we are seeing new pictures of undiscovered sea creatures all the time. I mean, something like the mega mouth shark is
a fairly new discovery. It boggles the imagination to think of what they could find.
Maybe there are some giant monsters down there. Really creepy things.

What's also interesting is that the ocean really is very shallow compared to the diameter of the earth. Seven miles is nothing really. As much as I expected much deeper it's still a daunting thought though.

But i thought came to mine when I was revisiting the thread. What would be the temperature at the bottom of the trench. Should be very cold because that area, the sunlight will never reach. But then, it is nearer to the core of the Earth which contain molten rocks so it should be hot?
