How big and heavy are icebergs?

Answer 1

200,000-300,000 tons. That's a lot

Answer 2

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.

Answer 3

Icebergs come from large pieces of a glacier that are now floating on the water.

The glacier will have a temperature several degrees below that of 0deg C, but ice does have thermal conductivity, and eventually will melt. The ice towards the outside will approach closely the temperature of the surrounding water but still has to gain much heat in order to transit from ice to water. Remember latent heat of fusion?

So melting is slow, but inexorable. The ice a few metres in will be colder, but determined by the source temperature.

Answer 4

Icebergs can vary in size, but they can range from the size of a small car to larger than a city block. In terms of weight, icebergs can weigh anywhere from a few thousand tons to over 200,000 tons.

Answer 5

200,000-300,000 tons. That's a lot

Answer 6

All of it
