It is not so much that the oceans are blue (or blue-green) as it is that the water quickly absorbs all light that is reddish or yellowish in color, leaving mainly blue-colored light.\n\nIf you go SCUBA diving and take pictures, you are always amazed at how mich brighter the stuff appeared when you were down there and how it tends to look kind of dull when you look at the pictures -- thsi is because your brain compensates for the lack of red light when you are down there, but the camera does not.  So when you look at the picture in normal light, they have no reds or yellows in them and look really dull.\n\nTo correct this, professional underwater photographers carry special lights with them to replace the reds and yellows.  They also use colored filters on their camera lenses sometimes to help balance the colors out better.\n\nAlso depending on where you are, the ocean water can have a lot of algae or other microorganisms in it that tend to give it a slight greenish tint and make it impossible to see more than 50 to 100 feet through the water.  In other parts of the world the ocean water is so clear it almost looks like a swimming pool.\n\nSpeaking of swimming pools, most of the "color" in those pools is actually due to the color the pool bottom is painted rather than any color of chlorine in the water.  The water is pretty much crystal-clear but the reflections of the slightly bluish paint used on the pool bottom make the water look more blue than it really is.

The average depth of the oceans is about five times the average elevation of the land. In general, the continents stand about three miles above the ocean floor. According to the National Geographic Atlas, the deepest-known part of the ocean measures [10,924] meters (35,839 feet), in the Marianas Trench near Guam. If the world's highest mountain, Mount Everest (29,141 feet), were to be placed into this trench, it would be covered by over 1.25 miles of water.

the sea and sky is blue because of light refraction\n\nthe sea absorbs the longer wavelenghts of light which are near the red end of the visible spectrum, and reflects blue to our eyes which we see. \n\nthe sky reflects all of the light waves in the particles in the sky, water, CO2, Hydrogen, etc., and as it gets nearer to the earth where we can see, most of the red end of the spectrum has been absorbed and the blue is reflected back to our eyes. \n\nand sometimes there are particles that absorb other parts of the spectrum, which accounts for the colors of sunsets and etc.

The deepest part of the ocean is the Mariana Trench in the South Pacific Ocean. The depth of the ocean here is about 35, 839 feet (10,927 meters).

Challenger Deep in the Mariana Trench is the deepest point in the ocean. Measurements varying from 35,797 to 35,838 feet have been taken.

it's not actually, if you look at the ocean, from the top it is blue becaues it is reflecting the light from the sky.   if you are underwater, it looks blue because the blue light is dispersed the least, meaning that the blue light penetrates farther into the water than the other colors of light.

328 million gallons is a gross under estimate. If your estimate of suface area of 68 million square miles is correct.... and thre is 5280 feet in a mile... and 7.48 gallons (US liquid measurement)per cubic foot... that would mean there is 208.5 MILLION gallons of water in 1 square mile of ocean that was only 1 foot deep.\n\nA cubic mile of water contains 1,101,040,680,960 gallons of water... so IF the estimate of 68 million square miles of ocean is correct, and the ocean were and AVERAGE of 1 mile deep (and I assure you its deeper)  then there would be 74 million of TRILLIONs of gallons of water in the ocean... to spell that out ... 74,870,766,310,000,000,000 gallons of water in a body of water 68 million square miles in area and 1 mile deep... again.. this is if the estimates give were correct.\n\nHowever the given estimates are not correct... the ocean covers approximately 140 million square miles and has an average depth of 12,220 feet. which is just over 2 miles... so the actual calculation should look like this.... 5,280 x 5,280 x 12,220 x 140,000,000 x 7.48  giving you  a whopping 356,753,863,100,000,000,000 gallons of water contained in the worlds oceans... APPROXIMATELY\n\n... I had better get a best answer for this....

the land masses do not float on the sea rather the seas fill up the low lying areas of the earths crust so when you dive to the bottom of the sea you will hit the earths crust(after going through various layers of mud and organic matter. the deepest-known part of the ocean measures 10,924 meters (35,839 feet), in the Marianas Trench, i think i'm right in saying that we have dived down to around 7000m (7km).\nOnce you hit the crust (sea floor) and keep going you would then go through the earths various layers (not possible!) and eventually come out the other side!

There are several theories:\n\n1. Blue wavelengths are absorbed the least by the deep ocean water and are scattered and reflected back to the observer’s eye \n\n2. Particles in the water may help to reflect blue light \n\n3. The ocean reflects the blue sky

The deepest part of the ocean floor is the Aleutian Trench off of the Aleutian islands (somewhere in the pacific. You will have to google). Man does not have the technology to reach the ocean floor.  Would be interesting if they could. I can certainly imagine that there are numerous sea creatures we have yet to discover.
