What are the lyrics to Beside You by Mariana's Trench? by Q: I'd like the full lyrics to the song Beside You by Mariana's Trench. No links, paste them here. Easy 10 points :] (And don't tell me, "Google it, lazy." I have my reasons for not using Google.)

A: When your tears are spent on your last pretense And your tired eyes refuse to close and sleep in your defense When it's in your spine like you've walked for miles And the only thing you want is just to be still for a while If your heart wears thin I will hold you up And I will hide you when it gets too much I'll be right beside you I'll be right beside you When you're overwhelmed and you've lost your breath When the space between the things you know is blurry nonetheless When you try to speak but you make no sound And the words you want are out of reach but they've never been so loud If your heart wears thin I will hold you up And I will hide you when it gets too much I'll be right beside you I'll be right beside you I will stay Nobody will break you Trust in me, trust in me Don't pull away Just trust in me, trust in me Cause I'm just trying to keep this together Cause I could do worse and you could do better Tears are spent on your last pretense And your tired eyes refuse to close and sleep in your defense If your heart wears thin I will hold you up And I will hide you when it gets too much I'll be right beside you Nobody will break you If your heart wears thin I will hold you up And I will hide you when it gets too much I'll be right beside you Nobody will break you

What kind of freaky stuff do you think lives at the bottom of the Challenger Deep in the Mariana Trench? by Obama is not my president Q:

A: If by 'freaky stuff' you refer to lifeforms, there must be many we still don't know about. As to freaky...well I find humans freakier than any lifeform we've discovered so far. We're supposed to be the thinkers, we modify our environment to suit our needs, we make these great scientific advances, and yet...we hardly know how to communicate properly, we are hedonist and selfish, and dumb to boot sometimes. At least the lifeforms deep in the Mariana Trench just have to worry about living, which is more than I can say for humanity.

I need help with the Mariana trench? by Evan Pepper Q: What was the Mariana trench like in the past - geologically speaking. and what has it done since then and what is it still doing?

A: http://www.marianatrench.com/ http://en.wikipedia.org/wiki/Mariana_Trench

If you were an animal in the Mariana trench what adaptations would u have? by im ur daddy Q: plz im being serious i need real adaptations the animals really have. thnx i need couple for adaptations you need to explain hwo and y dude some research b4 u talk crap aight

A: skin and organs which are adapted to face damn high pressure some bacteria to produce artificial light uses fluorescent tentacles to lure prey. The deep sea is also an extremely hostile environment, with pressures between 20 and 1,000 atmospheres (between 2 and 100 megapascals), temperatures between 3 and 10 degrees Celsius, and a lack of carbon dioxide. It has also been found that the deeper a fish lives, the more jelly-like its flesh and the more minimal its bone structure. This makes them slower and less agile than surface fish.

The Mariana Trench is a boundary between? by iampimp33 Q: The Mariana Trench, site of the deepest known point within the Earth's crust, is a boundary between the following types of tectonic plates Divergent/Transform Transform/Conform Ocean/Continent None of the choices are correct Continent/Continent Ocean/Ocean

A: Trenches are usually ocean-ocean or ocean-continent, so you could've eliminated some of the answer choices. To get the answer, you could've used Google Earth to look at the Mariana Trench. It should be obvious that it's an ocean-ocean convergence.

which is the densest animal? If dead and dropped in the Mariana trench; which would sink to the bottom? by LongXitian Q: I suspect some kind of whale (which sink to the bottom on death or hagfish which lives down at great depths but does anybody know?

A: Whenever any dense animal that will sink it's lungs will get filled up with water so it could be the blue whale if it's lungs was big enough increasing it's weight...but it could be a elephant.

Is it possible to scuba dive to the bottom of Mariana Trench in the Pacific Ocean with normal scuba gear? by Q:

A: The deepest a person can dive in scuba gear is about 100-150 feet. The Mariana trench is 35,994 ft. At that depth the pressure of the water is about 1000 time sea level pressure. You would die instantly.

what is the landscape in the mariana trench? by Q: how rocky, what is it made of, what created it (the land scape)

A: Sometimes a piece of the ocean floor (called a plate) will form a crack, and one side of the crack will sink beneath the other side. As the sinking side falls into the Earth’s mantle below, it pulls the rest of its plate with it. The ocean floor deepens along this crack. The sinking sea floor grinds against the other side of the crack and tears pieces off to be carried down into the Earth. The overall result is a long, deep trench that marks the location of the initial crack. We call such features subduction zones or oceanic trenches. This process is how the Mariana Trench formed.

Ufo bases are on moon, lake baikal, mariana trench, fake mountain in tibet? by Q: demons take care of these bases. buddhists consider the fake mountain the holiest (of course, demons guard this satanic mountain whose height is 6666 meters). well-functioning evil city of atlantis is underneath mariana trench (pacific ocean). these aliens are demons. the only way to fight them is with christian prayer.

A: Where do u get ur beliefs from? Sounds like u been brainwashed by some money pumping christian hippy.

Has any submersible (manned or not) ever explored the bottom of the Mariana Trench? by J K Q: What is the deepest depth achieved and verified?

A: Yes they have, the Treiste naval bathyscaphe from the USA reached the bottom on January 23rd 1960 with two men onboard. 10,916 meters (35,813 ft) was officially verified and achieved by the submarine. They apparently saw 30cm sized sole and some shrimp.

how close is the Mariana Trench to the center of the earth? by Q: just wondering how close this trench goes to the center of the earth

A: In a proportion sense, a small scratch on a billiard ball comes closer to the center of the billiard ball than the Marianas trench comes to the center of the earth. The Marianas trench, at 6.85 miles (11.03 kilometers) is about 3,393 miles (6440 km) from the center of the earth.

What would be the height from the bottom of the Mariana Trench to the peak of Mt. Everest? by TeejSSX16 Q: I just thought of this question and I want to know. Thank you to anyone who answers!!!!

A: the marianas trench is 36201 feet deep the maximum height of mt everest is 29,029 the difference would be 65230 feet

Does anyone know what is at the bottom of the Mariana Trench? by kenny g Q: Has anyone even put a Camera down that far? Have they scanned it or something? Please tell??

A: Challenger Deep (deepest point in the Mariana Trench and in all the Oceans) got its name from the British survey ship Challenger II, which pinpointed the deep water off the Marianas Islands in 1951. Then in 1960, the US Navy sent the Trieste (a submersible - a mini-submarine designed to go really deep) down into the depths of the Marianas trench to see just how far they would go (read the original press release). They touched bottom at 35,838 ft/10,923m. That means, while they were parked on the bottom in the bathyscaphe, there were almost seven miles/11km of water over their heads! The specimen in the photo on the deepest creature page was dredged up with 129 others from the Challenger Deep. This little guy is only about 4.5 cm long, but in amphipod terms, that’s a world record. Amphipods are flea-like creatures that are one of the most plentiful species of living things in all the worlds’ oceans. Many species of amphipods are from 1 to 10 mm long, with the largest specimens growing up to 30mm. Finding living creatures at the bottom of the ocean in the Challenger Deep was exciting for the scientists who discovered them. They were equally surprised by the sheer size of these world-record holding amphipods. Extremely Barophilic Bacteria Isolated from the Mariana Trench, Challenger Deep, at a Depth of 11,000 Meters: Two strains of obligately barophilic bacteria were isolated from a sample of the world’s deepest sediment, which was obtained by the unmanned deep-sea submersible Kaiko in the Mariana Trench, Challenger Deep, at a depth of 10,898 m. When the Trieste finally settled on the bottom, it raised clouds of fine white silt. Dr. Andreas B. Rechnitzer, the scientist in charge of the dive, identified the "dust" as diatomaceous ooze, the silica skeletons of small sea creatures, often used as scouring powder. In effect, the Trieste landed in a cloud of Bab-O. Clearly visible when the dust settled was a white flatfish about one foot long. It seemed healthy and it had eyes, although the nearest trace of sunlight was more than seven miles overhead. Swimming six feet above the bottom were a shrimp and a jellyfish, neither of them bothered by the enormous pressure on their bodies. The very fact that these creatures were living and healthy proved that the water had oxygen in it. Therefore it must circulate, because if it were stagnant in the trench, its oxygen would long since have disappeared.

How long would it take t get from the Phillipines to the Mariana Trench? by Megfla Q: well basically as above, if you were in an average boat (speed wise, also, im sorry i don't really know how fast nots are and whatever they are :/ ) thank you x

A: By boat will take days because the distance is like going to Japan.

What is the pressure at the bottom of Mariana Trench? by Ali Q: Is there any living animals there?

A: Te pressure is around 108.6 MPa whhich is about a 1000 times thhe pressure at sea eve. And yes tere are animals and plants tere. Some bacteria and plankton live tere

Would you rather climb the Mount Everest or dive to the bottom of the Mariana Trench? by Marina Marina Marina Q: What would be more thrilling for you and why?

A: I'd love to be able to climb Everest! But vigorous training would be required to do this. The Mariana Trench would be pretty cool too, but there wouldn't be a whole lot to see down without the aid of the submersibles exterior lights. Still...it would be exiting! I guess my choice would be Mount Everest...let the training begin!

How did they survive the dive to the bottom of Mariana's Trench? by Jake S Q: In 1960 Jacques Piccard and Don Walsh made a manned dive to the bottom of Mariana's Trench, the deepest part of the world's oceans. I know very little about diving but am still amazed at this type of dive with the amount of pressure that is present at those depths. So how was survival possible? Would there not be extreme strain on the body? And how come there hasn't been a manned dive since, only two unmanned dives? Thanks

A: well i dont know about that deep of a trench but in korea, people skin scooba down to get oysters, clams or something and they dont even wear oxygen masks. they do it for most of their lives and i heard that as they come up, they can't exhale or the sudden pressure change would literally burst their lungs so they whistle it out. i dont know if that made sense. well, other than that, all sorts of crazy things happen. like people surving a knife stab in the head, gunshots in the head, etc.

What's the state of water at the bottom of the Mariana Trench? by Sourcerer Q: OK, I've calculated that the pressure at the bottom is a bit more than 100 MPa. On the Internet, I found that the temperature is 1-4 degrees Celsius. Shouldn't the water then be in its solid state (frozen)? If it isn't, why?

A: Water is special because when water freezes, it tries to expand. Most other things contract. So trying to crush water is actually keeping it from freezing.(expanding)

How much is water compressed in volume at the bottom of the Mariana trench? by hairy4paws Q:

A: Once, the Beebe bathyscaphe was lowered on a chain to several thousand feet in an unmanned trial. When it resurfaced and the first hatch bolt was undone, it shot out like a bullet. Somehow high pressure water had found its way in. This proves that water isn't completely incompressible. Experiments have shown that at much greater depths than our ocean trenches, like 80 km. or so, the pressure would keep water solid even at high temperatures. At the bottom of the Marianas Trench the pressure is about 1000 times sea level pressure. The volume of water decreases by about 10% when taken down to that depth. To reduce it to half its sea level volume, you'd need to compress it to 10 000 atmospheres.

Why was there only one manned dive to the Mariana Trench? by Freakazoid Q: Is it dangerous? Uninteresting? There were 6 manned missions to the Moon, after all.

A: Dangerous? Extremely. A hull failure would cause a human to be squished to the size of a napkin almost instantly. Uninteresting? I thought that the saga of the robotic probe that went down last month was fascinating. But personally I'm astonished that they made the one manned dive. We can and will colonize the moon, but could never live at the bottom of the trench. It's little more than abstract knowledge. And those guys who went down were c*r*a*z*y!

What would happen if a megatsunami happend in Mariana Trench? by Josh W Q: How big do you think the wave would be, scientificly though, no silly answers

A: Panic on a massive scale.

What is the estimated temperature of the Mariana Trench? by I love my little Madelynn Q: how cold would the water be that far down?

A: The deep oceans are generally about 3 C (37.4 F), perhaps a bit colder. The bottom of the Mariana trench is about 1 C (34 F).

How much does it cost to rent a submarine to go to the bottom of the Mariana trench ? by mark Q: I spent half my savings so far on a CVS disposable underwater camera to take pictures while I am down there. how come no one realized this was not a serious question. I was expecting mocking answers and got none. damn you all to the bottom of a trench.

A: I don't think it's possible to go down their by yourself simply by renting a submarine. Only three descents have ever been made, and they were all heavily financed and manned by very experienced sailors and divers.

What plants are found in the Mariana Trench? by Laura H Q: Please include links or pictures if possible. Thank you! Thanks! But what about near the hyperthermal vents? I mean hydrothermal ;)

A: This could be a "trick question!" If you mean in the depths of the Marianas Trench, there would be no plants because light doesn't penetrate that deeply. However, there are chemosynthetic bacteria that take the place of photosynthetic organisms in providing a source of nutrients to the other creatures that live in association with the bacteria. In the near surface waters of the Trench, the normal phytoplankton would be the photosynthetic organisms in the food web.

How do Fish survive in the Mariana Trench? by dangitztiffany Q: The pressure down there is appx 1,099 times more than surface. How do the fish survive, how do they keep from crushing into nothing from the high pressure?

A: High pressures like those a fish would experience at the bottom of the Mariana Trench would easily crush any air-filled space. However, fishes in general have far fewer air-filled spaces in their bodies than terrestrial (land) animals. Also, deep-sea fishes take this a step further by losing or not inflating their swimbladder, which is a gas-filled organ that fish use for buoyancy and occasionally for gas exchange. Because the fish still needs to be neutrally buoyant in order to swim, most deep-sea fishes have extra fat (which has a lower density than water). The water in the cells and tissues of the fish is at the same pressure as the ambient (outside) pressure. Water is not compressible, and therefore there is no "room" in the body for anything to be crushed. While that explains why they can maintain their shape and structure, there are still many physiological (body chemistry) problems at that depth. These problems are caused primarily by proteins behaving differently at high pressures. Scientists continue to discover different ways that deep-sea fishes modify their proteins in order to help them function properly.

Why hasn't anyone decended to the bottom of the Mariana trench in the last 46 years? by meansawbean Q: Since 1960 no human has been to the deepest known point in our oceans. Why is this? Is it that it is too expensive or maybe lack of interest?

A: You're WAY misinformed, dude. Scientists from the University of Texas at Dallas and their academic partners in Japan have been diving to the bottom of the Marianas Trench off and on for years! Typically, they use the DSRV Alvin and have made many dives there. I am sure that there are others who have also been conducting research there; though not an "every day event", it's not that uncommon. You need to research this a bit more thoroughly. The Alvin gets "rented out" (by Woods Hole Oceanographic Institute) to scientists from all over the world and every year many, many DEEP dives are conducted to deep sea rifts and trenches all over the planet.

has man ever traveled into the Mariana Trench? by Takio Q: hey, has a human being ever dived -in any kind of contraption- to the floor of the Mariana Trench?

A: no

How long would it take if you fell into the mariana trench? by awesomeman Q: I found this topic to be interesting. the trench is over 7 miles down, and say it was drained out or something, and a 160 pound person fell into it. if you do the math right, you could proably get the right calculation. What's your estimate? I think it would take about 7 minutes to hit the bottom depending on the persons weight, because the heavier you are the faster gravity pulls you.

A: The speed of a body falling freely in the Earth's gravitational influence is: sqrt(2gh) g->gravity h->weigh in kilograms 160 pounds = 72.5747792 kilograms g=9.8 m/s^2 SOOO.... 7 miles = 11265.408 meters SOOO.... ==>37.56594 mph => 11.18033989 minutes before you hit the ground :S I don't know if I'm entirely accurate....

what does the Mariana Trench have to do with tectonic plates? by Q: Please explain thoroughly and also explain what the Mariana Trench is too! :D

A: The Mariana Trench is the deepest part of the world's oceans. It is located in the western Pacific Ocean, to the east of the Mariana Islands. The trench is about 2,550 kilometres The Mariana Trench is part of the Izu-Bonin-Mariana Arc geological boundary system that forms the boundary between two tectonic plates. In this system, the western edge of one plate, the Pacific Plate, is subducted beneath the smaller Mariana Plate that lies to the west. Because the Pacific plate is the largest of all the tectonic plates on Earth, crustal material at its western edge has had a long time since formation (up to 170 million years) to compact and become very dense; hence its great height-difference relative to the higher-riding Mariana Plate, at the point where the Pacific Plate crust is subducted. This deep area is the Mariana Trench proper. The movement of these plates is also indirectly responsible for the formation of the Mariana Islands (which are caused by volcanism as a result of subduction of water trapped in minerals). At the bottom of the trench, where the plates meet, the water column above exerts a pressure of 1,086 bars (15,750 psi), over one thousand times the standard atmospheric pressure at sea level.

Has any human or robot been to the bottom of the MARIANA TRENCH? by Syn Q: Has any human or robot been to the bottom of the MARIANA TRENCH,if not how far they went down,in the future will they go to the bottom,and what is down there.

A: Yes humans have been there In 1960, the US Navy sent the Trieste submersible to the bottom of the Mariana Trench, Don Welsh and Jacque Piccard were on board at the time The Japanese sent a robot in 1984, and they sent another one in 1995

why is the mariana trench so important? by denisha k Q: why is the mariana trench so important? and the information about it so important ?

A: the mariana trench is so important because it is the deepest part of the ocean and some scientist believe that ancient dinosaurs might live down it's just a theory.

The Mariana Trench marks a subducation zone between the Pacific and Philippine plate.? by Moon15 Q: The Mariana Trench marks a subducation zone between the Pacific and Philippine plate.? which of these two plate subducts and which remains on the surface and explained why?

A: The Pacific Plate subducts below the Philippine Plate because the Pacific Plate is older and denser than the younger Philippine Plate. Lighter will "float" over denser, and denser with "sink" beneath lighter in any convergent plate boundary system.

how did the mariana trench form? by cookiefart91 Q: how did the mariana trench form? also when did it form?

A: Sometimes a piece of the ocean floor (called a plate) will form a crack, and one side of the crack will sink beneath the other side. As the sinking side falls into the Earth’s mantle below, it pulls the rest of its plate with it. The ocean floor deepens along this crack. The sinking sea floor grinds against the other side of the crack and tears pieces off to be carried down into the Earth. The overall result is a long, deep trench that marks the location of the initial crack. We call such features subduction zones or oceanic trenches. This process is how the Mariana Trench formed.

The Mariana trench is located in the Pacific Ocean at a depth of about 11 000 m below the surface of the water? by Q: The Mariana trench is located in the Pacific Ocean at a depth of about 11 000 m below the surface of the water. The density of seawater is 1025 kg/m3. (a) If an underwater vehicle were to explore such a depth, what force would the water exert on the vehicle's observation window (radius = 0.118 m)?

A: 11 000 m * 1025 kg/m3 * 9.81 = 110607kN/m2 area of window is 0.0437 m2 force is 4838kN

If you lost a ship in the Mariana Trench, how long would it take to sink to the bottom? by Q: I am just wondering that, since the Mariana Trench is the deepest part of the earth (over 30,000ft), how long would it take for an averaged size ship to sink to the sea-bed? Also how long would it take for a diver to decend to the bottom to find a ship etc?

A: It depends on the negative buoyancy factor and how much air is trapped in the hull. Could be hours.
