how much of a glacier is under water and is it possible for it to meltover and prove it?

Question

will it flood over everything?

Answer 1

90% of an iceberg is under water
frozen water is 8% less dense then liquid pure water - thus ice flows on water. ocean water has 35000ppm of salts (which make it more dense) so it "lifts" more of the iceberg out of water.
Icebergs usualy melt around equator.

Glaciers are massive inland ice masses. if it will melt it would flood a large area but not everything.
This did happened in the end of ice age and had huge impact on relief. Note that glaciers where much more bigger then.

Answer 2

Here's an example; an ice cube in a glass of water- how much is above water, not much right? Ice bergs are the same way depending on shape and thickness. Salt water being a little thicker in consistency will fractionally affect bouyancy making the berg float a tiny bit higher than in fresh water. Only about 1/10th of the average berg is above the surface. The freaky environmental spooks think global warming is real. It kind of is, but not in the panicy way they think and man has little to nothing to do about helping or hindering it. Back in the late '70s, the evos were predicting the new ice age because of a few bad winters in a row. Man can NOT do anything about it except adapt. When a big berg fall in the water, it's not noticed in the water levels around the world. Water, when it freezes, expands. If you had a million gallon container and put a solid block of ice that filled every corner to the top, when it melted, it would only be about 1/3rd. full. Put 1 ice cube in an empty container and let it melt. Small amt. left, right? OK. Melting bergs aren't a problem. Fact.
Another fact. Glaciers are setting for the most part, on land. How they get there? Lotsa lotsa years of cold and snow (centuries) that never gets melted, just keeps building up. It takes clouds darkening the skies to make all that snow & ice. which helps keep temps low. A very few sunny years gets it melting pretty fast but a moving glacier moves very sloooow whether expanding from cold or melting from heat.
The earth's cycles depend on several dynamic things; the Moon and the Earth both travel in eccentric and erratic orbits. Earth to the sun, Moon to the Earth. It takes lotsa time to do that. Maximum distance to minimum closeness can take 100 years more or less (Moon around Earth) and centuries (Earth around Sun). We can't change anything. Nothing. Not 1 degree. Not 1 inch of sea level. "An Inconvienient Truth" is a big Bald Faced Lie! It was talked into "reality", the old "tell a lie long enough and people will start to believe it" trick used by bill clinton and Vladmir Lenin and Karl Marx. You remember Lenin and Marx, the fathers of communism and socialism? And you didn't know bill clinton studied and idolized them?? Now is it starting to make sense? Man isn't murdering the Earth! The "ozone layer" isn't disappearing; the ozone molecules get compacted by cold, gets heavy freezing together and simply falls to the cold Earth poles. When the molecules get warm enough they are released back into the upper atmosphere. The Earth isn't "wounded" or "bleeding" and the oceans aren't boiling and the Arctics arent melting and if they were, we wouldn't notice. Scientists would because they have the tools to measure that stuff with Chicken littles got their heads together and cooked up a grand scheme to steal billions and billions of $$$$$$ of your tax money using fake science and peoples gullibility and ignorence. When they politicians about it, they wanted some of that pork pie, too. So a deal was made in secret and the rest is liberalism at it's worst.
And that's the WHOLE TRUTH! Probably the first time you've ever seen all the truth about environmentalism laid out in front of you, Hmmmm?
Moral of the story? If they say "I'm from the EPA. And I'm here to help you." You just tell them "Wrong address! You gotta go 150 miles (whichever direction, south means Hell) and slam and lock the door.

Answer 3

No the level will not change. Ice is frozen water and it floats on water so it is not as dense as water. About 90% of the volume of the ice will be below the surface of the water it is floating in.

But it really doesn't matter the ratio. Since it is floating the its entire weight is displaced by the volume of the ice submerged under the water. When it melts its volume will decrease to the same volume as the water it displaced so the level will remain the same.

Its easy to prove this although common sense you give you the answer without a test. Put ice in a glass then fill it up with water. The ice will float up and stick out past the top of the glass. Let the ice melt and see if the glass runs over, it won't.

Answer 4

Hi, I once saw a special on TV about the icebergs that float in the sea near the North Pole and they are as big under the ocean as they are big on top. They are melting too and the polar bears are losing their places to feed on seals. ...I do not know too much about glaciers just that they are melting too and eventually all this melting water will increase the levels at the coastlines.

Answer 5

If it's already floating in the water, then melting will not increase the water level. If it is either stuck on the bottom and more than 10% sticks out over the surface of the water, or it is on land, then its melting will increase the water level of the ocean.
Presently the oceans water levels are rising at about 3mm (about 1/10th of an inch) per year.

Answer 6

I did not know that part of a glacier was under water.

Answer 7

On average about 90%. Yes, it can melt and flood quite a bit of the world. It's been happening already.

Answer 8

a glacier floating in the ocean is actually 90% underwater, only 10% is visible above water... i don't understand the rest of your question

Answer 9

about 95% is under water. and yes it can melt but that is unlikely
