For each part of the iceberg you see above the surface, there's a much bigger part below the surface, providing buoyancy for the part that is lifted into the air. Just as with ice cubes, most will float below the surface and a little will float above.
The size - well, that's determined first by how they break off from glaciers and shelf ice. Later by erosion and melting.
The iceberg was much larger than the Titanic. Icebergs have 90% below the surface of the water.
Icebergs float in the ocean because the iceberg is less dense than the water.
yes.if it isn't icebergs would sink.
It depends entirely on the size of the iceberg and where it floats. If it stays in cold water, it will last longer than if it floats down into warmer water. Larger icebergs last longer than small ones.
Icebergs have been naturally occurring longer than there have been humans. So the first human to see an iceberg was simply the first human that made it far enough north into the natural range of icebergs. And that's too far back in history for us who know who it was.
Icebergs are at their largest points when they break off of a glacier. Usually more than 92% of the iceberg's mass is underwater. For example, that was the problem with the Titanic. The captain thought it was just a puny iceberg, but under it was the rest of the MASSIVE iceberg. The iceberg punctured the belly of the boat, and water got into it, and when I saw water I mean A LOT of water. So that caused it to sink. So in conclusion icebergs are their largest when they break off of a glacier. For more information, go to www.minecraft.com/store -Courtesy of Sidney K.
It depends on how large it is. Icebergs vary quite a bit in size. The average iceberg in the Grand Banks area of Newfoundland (Canada) weighs between one and two hundred thousand tonnes. This is about the size of a 15 storey building in the shape of a cube. Icebergs more than double that size are found off Antarctica.
There is no maximum size that icebergs can have; they will be as big as gravity, temperature and 'local' factors will allow.The largest iceberg that has so far been documented, was an Antarctic iceberg that measured 335 x 97 kilometers (208 x 60 miles) which is larger than the country of Belgium.
In a condition of warm water and cold air, the bottom would melt faster than the top and it would roll over. As the ice on the bottom melted, it would become top heavy. I would think that it is not impossible for some icebergs. The more closely an iceberg resembles a sphere, (or log-like) the more likely that some rolling might occur. And I would think that while it might be unlikely, it is probably possible for some icebergs to be sphere-like. The same proportions of ice above and below the waterline will hold throughout the life of the iceberg; there would be no such thing as a top-heavy iceberg unless perhaps it got grounded on a shoal.
because the pressure of the iceberg is greater than the pressure of the boat and so if the boat hits it, the iceberg will hit the boat, make a hole, and all of the pressure holding the boat up will be released and the ship will sink.
When someone says that something is only the "tip of the iceberg", they mean there is much more to it than what you see at first. Like real icebergs, something like 90% of it is underwater where you can't see it. The tip of the iceberg is just what you see on the surface...there's much more to the story than that.
Captain Smith tried to avoid ice by traveling further south than the normal crossing route, but there were both more icebregs than usual and currents were also sending icebergs further south. Hence, that is why the Titanic struck an iceberg and is now sitting on the bottom of The North Atlantic Ocean.
An iceberg floats because water is one of the few substances that is slightly denser as a liquid than as a solid. This is why ice cubes float in water icebergs are made from fresh water. Because of the dissolved salts in ocean water, it is denser than freshwater, adding bouyancy to the icebergs. Most icebergs actually contain a lot of air. Far from being the solid blocks of ice many people imagine, icebergs are riddled with billions of tiny, trapped air bubbles, giving the huge bergs their white appearance. Yes and if you want to get more specific, the density of ice 0.9g/cm cubed and the density of water is 1 g/cm cubed so if you think of this out of 100, 90% of the iceberg is underwater and 10% is above the water. All has to do with density.
Icebergs are usually pieces of a glacier that breaks of into the ocean.
An iceberg, if melted, would be fresh water, or at least much less salty than seawater. There are a couple of reasons for this: * Icebergs tend to break off from glaciers as they reach the sea, and glaciers start out as precipitation (that is, fresh water). * Fresh water freezes at a higher temperature than salt water, so when freshwater ice contacts seawater, what happens is that some of the water component of the seawater freezes and the remaining seawater gets very slightly more salty.
It depend on if its hot tea or iced tea. If it's hot then the temperature of the tea is probably higher than a freezing iceburg
The iceberg is denser than the ship
The icebergs are melting because of heat trapped in our atmosphere by global warming is being pushed by global wind patterns to the poles.AnswerFor the same reason they have always been melting. Icebergs, you see, are large chunks of ice that break off from glaciers or ice caps. Once they break off, they float away on the ocean currents. 90% of their surface area is in direct contact with water. Liquid water, which, by definition, is warmer than ice. Heat exchange between the water and the iceberg causes the surface of the iceberg to warm until it melts. There is nothing at all out of the ordinary about icebergs melting. They have always been melting, and will always be melting. The fact that icebergs are melting has nothing at all to do with global warming. Warmer summer weather causes the melting. When winter comes, the glaciers will expand. Now, in SOME cases, the amount that melts in the summer is significantly more than the expansion in the winter.
They become professors if they are higher than a 'surgeon'
no. it melts An iceberg will float as long as it is in water. If you could put an iceberg in a liquid less dense than ice, the iceberg would sink.
They are chunks of floating ice drifting away from polar regions. The density of ice is just a little less than the density of sea water, so most of the volume of an iceberg is below the surface, and so a small-looking iceberg can have a huge volume of ice below the surface. The Titanic ran into an iceberg and was holed below its waterline so the water rushed in and the ship sank.
No. Seawater is salty, and it is more dense than fresh water. This gives seawater more buoyancy, and an iceberg will float "higher" in seawater than ice will in fresh water. But still 'most' of the iceberg will be under water at least 70% of it.
A glacier is older than an iceberg, because an iceberg is a piece of ice that fell off a glacier.
