When the icebergs melt or global warming happens, how could it cause flooding or sea level rise?

Question

Because when you have a glass of ice water, the water level stays the same even when the ice melts.????

Answer 1

It won't make the water level rise. In fact the water level will actually drop a very minute amount. Frozen water takes up more space than liquid. As the top of an iceberg melts, the iceberg below the surface (over 90% of the actual iceberg) rises. The area left void by the iceberg rising is taken up by the melted ice. When this water reaches the freezing cold, guess what happens? Yep! It becomes part of the iceberg again.

Plain and simple, iceberg and icecap melting and reforming has been going on ever since the world formed. Global warming ain't happening.

Answer 2

Melting icebergs will not raise the sea level, neithere will melting of the arctic ice fields. Both of these are already floating in the sea, so the effect of their melting will be a slight decline in seal level. But, most of the worlds ice is in land based fields, in Antarctica and Greenland. When these melt, water runs into the sea, raising the sea level.

Answer 3

yes the ice in the glass of water ,is a good example and it is absolutely true with the North pole ,which is ice already in the water ,when that melts it makes no difference to the water level except that tons of fresh water is lost ,

93% of all water on the planet , is salt and of the 7 % remaining 75% is locked in ice

However on the South pole ,glaziers ,mountain snow ,Greenland ,all of this ice ,some of it kilometers deep, is on LAND and all of this will run into the seas directly of via the rivers ADDING to the water, and so drastically effect the overall Global sea level

but nice try

Answer 4

Actually the level goes down when ice melts in a glass of water but you are missing one important factor. When the ice on land masses, Greenland, Antarctica, etc, melts that water adds to the amount of water in the seas and will raise the sea levels. It is not the icebergs, it is the ice and snow on land.

Answer 5

Because the ice cubes aren't suspended above your drink. It's not really about the icebergs but more the polar ice caps melting.

Answer 6

No it doesn't number one. Number two global warming is happening now. Also we are going to get flooding but the EAC east Atlantic current controls our weather. It flows down south warms up and goes up north to cool off global warming is making it harder and harder to cool off plus with the ice melting it is adding more fresh water to the salt water in the oceans witch is throwing everything off to. So we really don't have to worry about the ice melting and flooding the world but we are going to get intense storms. The planet is a living thing and we it gets to hot it will find away to cool itself.

Answer 7

The icebergs are made out of frozen water so when it melts it becomes regular water mixing with the ocean water to cause it to rise.

Answer 8

because the mass of the ice burgs hold so much water that when they melt the water level wil rise and cause global flooding

Answer 9

It's the ice sitting on land that's the problem.

Answer 10

because icebergs are made of water but froozen so its putting in more water
