Is it true that Less than 100 icebergs break off Greenland's glaciers each year?

No, it isn't. There are more than that, and recently the numbers have been rising. Worldwide, between 15,000 and 40,000 icebergs are calved from glaciers each year, and although some of Greenland's iceburgs are small, they are more abundant than that. :)

Why do glaciers float and not sink to the bottom of the ocean?
Glaciers are made of ice, which is less dense than water. Therefore, fragments of glaciers that break off into water, called icebergs, will float.
Is snow made from fresh water?
I should think it would be made of salt water since the icebergs I have heard of are all in the ocean. They are pure water as they are created from glaciers and since glacier ice is formed from falling snow and snow results from condensed water vapor in the atmosphere, the water from icebergs is quite pure.
Are glaciers less dense then fresh snow?
No. Fresh powder is softest.
Why are there less glaciers in Florida?

Does Portugal have glaciers?
Well. Nowadays it doesn't have any glacier . The last evidence of glaciers at Portugal where in the most intense part of the last ice age . This was more or less around 18-20 thousand years ago.

Why does the ocean water near the north pole absorb less heat throughout the year than ocean water near the equator?
Because near the north pole there are glaciers and icebergs. They reflect the suns rays, while near the equator, there are no glaciers.
What would happen if the icebergs started melting?
Icebergs are already melting, but they only add very slightly to sea level rise (Icebergs are fresh water, which is slightly less dense than sea water).
What are parts of icebergs?
Icebergs look small on top but are huge underneath. They are also very sharp. The iceberg that sunk the titanic scraped up the bottom of the ship and allowed water to get in, which weighed the titanic down, causing it to sink.
Why do icebergs float on the Arctic and Antarctic seas?
In the Arctic, sea ice forms from water cooled below the freezing point, at about -1.8 °C or 28.8 °F. When the salt precipitates, the fresh water freezes into ice. In the Antarctic, most icebergs are produced by coastal glaciers, formed from compressed snow over many years. Because water expands when it freezes, ice is less dense than the sea water, and will float at the surface. However, most sea ice floes and icebergs still have most of their mass below the surface.
If the worlds icebergs all melted what effect would this have on our planet?
Icebergs float, so their melting will not make much difference to sea levels. They are made of fresh water, and fresh water is less dense than salt water, so sea levels will rise, but only slightly.Ice caps (sitting on land) and glaciers, however, if they melt (Greenland and Antarctica) will raise sea levels by 200 feet or more (60 metres).
Why does an iceberg float in the ocean?
Icebergs float in the ocean because the iceberg is less dense than the water.

No. Fresh powder is softest.

Why do icebergs float when they are cold and cold water sinks?
Icebergs and ice are less dense than water, so they naturally float. The way their molecules are organised they have way more volume for the amount of mass they have than equal mass of liquid water. Cold water can be denser than warmer water, the molecules are closer together and not vibrating as much, so it sinks below warmer or less denser water (or any other liquid). It's the opposite of what happens with icebergs, even though they're made of the same stuff.
How would sea levels be affected if all of Earths glaciers got bigger and new glaciers formed?
If all of Earth's glaciers were to get larger and new glaciers formed, it would lead to a decrease in global sea levels. This is because glaciers are formed when snow accumulates over a long period of time, compressing into ice. As more ice is stored in glaciers, less water is in the oceans, resulting in a lower sea level.
