Help getting 4 marks: 'Outline the process of liquefaction'

Hello,

My question is:

'Outline the process of liquefaction'

Now, the question itself isn't the problem, I know what liquefaction is - however, it's 4 marks, and I only really think I have enough information to get 2/3 marks. Does anyone know what points I could make so that I could get full marks?

Thank you :-)

Here are some suggestions for a few extra marks...
- What causes liquefaction? Earthquake shaking/loading/blasting
- What types of earthquake waves are most likely to cause liquefaction?
- Where does liquefaction occur?
- What happens during liquefaction?
- Name drop an example of where/when liquefaction has occurred
- Use key words e.g saturated, water pressure, loosely-packed
