It is called a large chunk of ice afloat in the ocean:)\n\nP.S or an iceberg

The figure I have from a university course was 45m (roughly 80ft).  You can discount any ice floating on the sea, such as the North Polar icecap,the large ice shelves around Antartica and the sea end of glaciers as they havealready displaced the equivilent amount of water already (imagine a glass fullof ice and water, as the ice melts the glass does not overflow).\n\nIf all the ice were to melt the rise would not actually be directly equal to the amount of water resulting due to differences in the densities of salt and freshwater.  Taking the temperature into account the molten ice would be denser than the warmer saltwater so reducing the overall rise.

The density of pure water is 1.0\nThe density of ice is .92 (ice expands when it freezes, so the density drops)\nThe density of sea water is 1.025 (sea water is denser then pure water because it is salty).\n\nAn ice cube floating is a glass of water is 92% submerged (compare their densities.)\n\nAn ice berg floating in sea water is 90% submerged (.92/1.025)

ice floats in water because its 10% less dense than water, \n\nbut not all ice has to be ontop of water, so no not all the world's ice floating

what do you mean?  the ice is frozen over concrete if that's what you are looking for.

Somewhere in the Pacific Ocean.

The permanently frozen part of the earth's surface is called the Cryosphere.

Salt water has a lower freezing point than fresh water.

The deepest part of the Arctic Ocean is a mile deep. It is called the Hidden Ocean by researchers. It is located north of Alaska.

Oceans or more specifically the Pacific ocean is the largest source of water.\n\nThe largest source of FRESH water is the artic ice pack.\n\nLargest body of fresh liquid water (by volume) is Lake Baikal in Russia. Largest body of fresh water (by area) is Lake Superior between Canada and USA.

some of it dispursed among the earth's oceans. some of it is still frozen is polar ice caps. some is in the atmosphere. some of it is in ur toilet.

That would be a cold (or at least cool), dry mass of air that originated over a large region of land near the north pole.  (Not over an ocean, unless it was the Arctic Ocean, which is covered by ice.)

Good question!  You obviously know that glacial ice is not the same as frozen water in an ice cube tray in your freezer!  (glacial ice is compressed snow)  My initial response was that icebergs float, so yeah, it would float.  Then I thought that seawater is salty, which can cause more dense things to float and doesnt nescessarily provide a good proxy for a cup of drinking water.  Thennnnnn (you like following my train of thought here?) I remembered that icebergs calve into fresh water lakes, too and float.  So my long-winded non-quantitative answer is yes.  :)\n\nI have no idea if there is a difference in rate of melting, but my best guess is that it might take SLIGHTLY longer to melt.

The density of seawater:\n\nhttp://hypertextbook.com/facts/2002/EdwardLaValley.shtml\n\nThe density of ice:\n\nhttp://www.elmhurst.edu/~chm/vchembook/122Adensityice.html\n\nThe figures for the world's volume of freshwater are available on a number of sites and in various texts.  Suffice to say that about 97% of the world's water is oceanwater, and some 80-90% of what's left over is frozen in the ice sheets.\n\n''With ice being significantly less dense than water will melted glaciers and ice mass really cause the ocean to rise? And even if that is so, would the volume of ice melting have to be incredibly dramatic to cause even a small rise?''\n\nDefinitely.  Sea ice will not contribute to rising sea level, but ice sequestered in glaciers will, because it was ultimately derived from the ocean.  The volume of melting would not have to be dramatic to make life interesting; if Greenland alone melted, that would raise sea level by some 20 feet.  A much smaller rise over the next century, of one to three feet, would still be disastrous for the most low-lying areas of the globe.

old easy riddle. block of ice.

The fact that ice always floats on water should give you a clue!  The ice is obviously not as dense.  So you can infer from this something has happened during the freezing process.\n\nThe structure of a water molecule is One atom of hydrogen to two if oxygen.  As the water freezes hydrogen bonds form between the various water molecules and these stop the molecules packing as effectively so the ice is less dense.\n\nTry the source below.

A glacier is a moving mass of ice (frozen water).  Moving water is something you would find in a river.\n\nSometimes glaciers are referred to as "rivers of ice."  Which is true, but they flow at much much slower rates of speed.  The flow characteristics are similar in some ways, but very different in others.
