How deep is the ocean? Is it possible that dinosaurs could still be alive just somewhere in the deep blue...And what is at the bottom???

in some parts of the ocean it can be miles deep. the ocean covers 2/3 of the earth, and we find new species in it all the time. there are still many primitive species alive today, such as the shark and the horseshoe crab. they are species that are millions of years old. i think that there could be many more dinosaur related species yet to be discovered. it's completely possible.

There are definitely SOME prehistoric creatures down there. Sharks, for example, have not changed for millions upon millions of years. The coelacanth (pronounced SEE-la-canth) was discovered alive in the late 1950's but it had been known from its fossil remains much earlier. It was virtually unchanged after millions of years.
This leads to the idea that the ocean has not changed enough in the past for things to have evolved into unrecognizable forms. We could very well still discover some dinosaurs, or, rather, plesiosaurs, down there.
The deepest part of the ocean is the Challenger Deep in the Pacific, which is something like five miles deep. At the bottom of some parts of the ocean, it is possible to find nodules of rock which are mostly metallic elements-- concentrated ores. If copper and other metals were not so cheap and easy to mine on land, we might very well start mining the ocean floors for them.

To correct some mistaken beliefs first not all dinosaurs were land dwellers...in fact more fossilized remains exist of water based dinosaurs than do of land based dinosaurs. As to the oceans depths the most up to date findings show the Marianna's Trench to be over 7 miles below the surface of the water, or 37,000 feet. Many unknown species inhabit the oceans of the world and several of them have changed very little from the days of the dinosaurs...the Horseshoe crab for instance looks just the same now as it did during the time of the dinosaurs, there are going to be new discoveries the more we study the oceans depths and each of these will add to a better understanding of our oceans and the multitude of life that flourishes there.

The ocean is very deep, up to 35,813 feet deep. At the bottom is rock. There are no more dinosaurs alive on Earth.

The depth varies based on the underwater geography. I believe the avg depth is 2 mi, and the lowest point is in the trench in the Pacific Ocean where the techtonic plates are smashing together. I believe the depth there varies between 6-7 miles.
Under the water, there is rocks, mountains, caverns & volcanos in some areas, most notably in the middle of the Atlantic Ocean.
And, no, there aren't any dinosaurs. Dinosaurs were land animals and could not survive under water.

Oceans vary in depth. The Pacific Ocean is the deepest as well as the biggest overall. It is very mysterious about what is living on the bottom of the ocean. I think it is possible for prehistoric creature to live currently in the deep ocean. Scientists say that we know more about outer space the the deep parts of the oceans.

The deepest part of all the arth is approximatly 37,000 feet. It is refered to as the Mariana Trench and is located in the South Pacific.
No, dinosaurs were air breathing mammals therefore they would not be able to breath under water. Water weighs approximatley 8 pounds per gallon and exerts a pressure .434 pounds per square inch that is 1 foot high. Imagine the pressure at 37,00 feet. Compare the strength of a deep sea submersable to the the hide of a dinosaur. Not even close.
The bottom of the seas are covered with plant life, rocks, sand,
invertebrates,etc so on and on.

The deepest know spot is over 7 miles down. because of the extremely high pressure we do not know what is down there. A special sub went to the 6 mile level. No dinosaurs are not down there. The nearest living relative to the dinosaur are birds, that right when you eat chicken you are eating dinosaurs (sort of)

It's at least 2 miles deep in some parts of the Atlantic.

The ocean is REALLY deep.If you go down there you might never go up again.It's probably 100,000 miles deep.
The dinosaurs are already gone,or extinct, so the dinosaurs' bones are buried in the ocean sand.
