12. Iceberg Dynamics and Safety

Try these first

1. 1.

   What percentage of an iceberg is submerged under water?

   Hint

   Think about the ratio of visible to submerged parts.

2. 2.

   Define buoyancy.

   Hint

   Consider how some objects float while others sink.

3. 3.

   What portion of an iceberg is usually visible above water?

   • 1/8
   • 1/2
   • 3/4

   Hint

   Remember the ratio of visible to submerged parts discussed.

4. 4.

   True or False: Underwater melting can enhance iceberg stability.

   • True
   • False

   Hint

   Think about how losing mass beneath the surface affects balance.

5. 5.

   Discuss how different technologies today would have changed the outcome of the Titanic disaster and develop a strategy for iceberg monitoring.

   Hint

   Think of the advancements mentioned in our resource links.

6. 6.

   Calculate the potential height loss of an iceberg given an average melting rate and dimensions, and discuss implications for ship navigation.

   Hint

   Use basic arithmetic and consider the ratio of submerged mass.
