How far does the sea go down? What could be lurking at the bottom of it?

You'll have to go scuba diving. They live in the sandy bottom of the ocean just outside of the surf zone, well below the low tide level. Depending on how big the surf is in the area, they are likely to be in ten to thirty feet of water along sandy beaches and will be partially or shallowly buried in the sandy ocean bottom. I've seen them here many times when beach diving. \n\nYou can occasionally see an unfortunate sand dollar that has washed up on the beach that is still alive. If it is sort of furry, it may still be living. When they die they loose the outer velvety spines and become the smooth 'dollars' we are used to finding. \n\nHere is a website that explains a lot about sand dollars:\nhttp://www.wildsingapore.com/chekjawa/text/s620.htm

I don't think it could "fall" into the ocean.\nBut if you follow along with global warming rasing the sea level, then at some point if it stayed where it is, that location would be underwater.  I would have to think it would be moved further inland if that happened.

Somebody asked a very similar question awhile back: how much would sea level rise if all humans on earth were submerged in the oceans.  The answer was something like .17".  So "less than an inch" would be my guesstimation to answer your question.

It is 11000 metres below sea level.

If you removed all the sponges, you would remove some of the mass in the ocean displacing water. So in fact, the ocean would not be deeper, but shallower. \n\nI will leave it to the reader to estimate the reduced depth after sponge removal.

On even ground, probably a frisbee.\n\nAt the Grand Canyon, probably a rock since it has a long way to drop.\n\nHowever, if you drop something in the ocean where it's very deep (like the Marianas Trench), it will fall for about 6 miles.  That's probably a good place to hide a gimp you don't want anymore.

There is theory that says perhaps the fresh water aquifers under that area of the ocean rupture into the salt water, making the water less boyant.  That would sink ships loaded with cargo or near their max weight limit.  Yet it does not account for lost planes.  So who knows?

It is the area of land that is underwater for half the day and above water the other half. This is caused by the rise an fall of sea levels due to high and low tides.

They range in size from about 1 inch (2 1/2 centimeters) to 200 feet (61 meters) long. They have been drifting through the world's oceans for more than 650 million years.

it has to do with the depth of the ocean and how the sun is hitting it

Somewhere in the Pacific Ocean.

The dead sea in israel is 400m below sea level have a look at that.\n\nThere are some bacteria living in crude oil reserves underground check thos out.\n\nThe other animals that live and work far underground are miners. Have a look for the world's deepest mines to see what they live through.

Pacific Oacean Mariana Trench is over 36,000 ft. It would take a one pound ball of lead  1hr. 45min. to reach the bottom.

The Red Sea is not the lowest point on earth.  However, I do believe that you are thinking of the Dead Sea!  The Dead Sea is one of the lowest points on earth, and water that flows into it does not flow back out (it is called the dead see because it is so salty that no living thing can survive in it.  It's so salty that it actually makes it easier to float!)  The actual lowest point on earth is Mariana's trench, which is in the pacific ocean near Southeast Asia.  I believe that the depth is around 28000 feet (the last time I knew, no submarine had ever touched the bottom, but they did come to within about 3 feet of the bottom).  I hope that that sufficiently answered your question.

Marianas trench is 35,813ft down and is in the pacific ocean\nsouth of Japan. near the Mariana Islands most likely hence the name ......it's where in the movie "The Core" they lanched their ship.The PSI(pounds per square inch)is over 1000 times standard atmospheric pressure at sea level..

Well,  there is a new island forming just south of the big island.  It is about 3000 feet under sea, and is not expected to break the surface of the ocean for another 10,000 years.  I'd say that is pretty fast in geological terms.
