Icebergs
-
Weight
The ice that actually forms the icebergs though, may be more that 15,000 years old. It all depends on how big they are. The larger ones can weigh more than 10 million tonnes.
-
Tallest
The tallest known iceberg in the North Atlantic was 550 ft high, extending out of the water to almost the height of the Washington Monument, it is the tallest iceberg recorded to date.
Size
The exact size of the iceberg will probably never be known but, according to early newspaper reports the height and length of the iceberg was approximated at 50 to 100 feet high and 200 to 400 feet long.
What
An iceberg is a large piece of ice floating in the sea. They come in all shapes and sizes, from ice-cube-sized chunks to ice islands the size of a small country.
Largest
The largest iceberg people know about was called B-15. It started to break up into smaller pieces, which still remained in 2008.
Meaning
The term “iceberg” means chunks of ice larger than 5 meters across. Smaller icebergs, known as bergy bits and growlers, can be dangerous for ships because they are harder to spot.
Where
The North Atlantic and the cold waters surrounding Antarctica are home sweet home to most of the icebergs on Earth
Danger
Icebergs are dangerous because they are huge and they float low in the water which can cause danger to the ships. They tend to flip over at times. When they flip over the energy is so great it can cause tsunamis and on occasion can trigger earthquakes.
How it melts
On the iceberg surface, warm air melts snow and ice into pools called melt ponds that can run through the iceberg and small cracks. At the same time, warm water laps at the iceberg edges, melting the ice and causing chunks of ice to break off.
