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.
How do icebergs form relating to the properties of water?
Icebergs form when chunks of ice break off from glaciers or ice shelves and float in the ocean. This happens due to the unique property of water expanding when it freezes, making ice less dense than liquid water. As a result, the frozen ice floats on the surface of the ocean, forming icebergs.
How are icebergs formed and why do they float?
Icebergs are formed when chunks of ice break off from glaciers or ice shelves. They float in water because ice is less dense than liquid water. This is due to the fact that ice takes up more space than the same amount of liquid water, allowing icebergs to displace enough water to stay afloat.
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.
Where is most fresh water found on the Earth?
Most freshwater on Earth is found in glaciers and ice caps, with around 68.7% of the world's freshwater stored there. Other significant sources of freshwater include groundwater (30.1%) and surface water in lakes, rivers, and wetlands (less than 1%).

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.
Is icebergs more or less dense than water?
Icebergs are less dense than water because they are made mostly of frozen freshwater, which has a lower density than liquid water. This causes icebergs to float in water with a portion of their mass sticking out above the surface.
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).

Is the density of an iceberg and seawater equal?
No, an iceberg is approximately 10% less dense than seawater. This is why it floats
