Rogue Waves:

Firstly, let us learn about some big waves in general. These are often called “Rogue Waves”. Look at the following website to answer the following questions on Rogue Waves..

Rogue Waves in Alaska


Describe what are rogue waves


Explain two ways that rogue waves can be produced


Explain what wave action is responsible for producing rogue waves

Describe how the height of the rogue waves is related to the individual waves


Explain how the height of the rogue wave is related to the wind speed. If the wind speed increased from 40 knots to 60 knots write down what you would predict the wave height for the rogue wave to increase by.

Monster rogue waves are surprisingly common. They have caused many super tankers to be sunk. Look at these images to see the awesome force of these killer waves.

Now look at these websites to learn about how many super tanker ships have been sunk by the deadly rogue waves.
