Important Keywords
- Ancient barrier island: finer sandy material - much more compact and consolidated than modern deposits, firmer than modern deposits yet still fairly soft
- Artificial Fill: muddy with water present - other materials are in the mud like brick and concrete remnants
- Cooper marl: very compact sediments
- Earthquake: occur on faults along plate boundaries and are caused by the release of energy built up in the earth where rocks are sliding past one another
- Fault: a fracture along which the blocks of crust on either side have moved relative to one another parallel to the fracture and cause earthquakes to happen
- Liquefaction: occurs when sediments are not compact and filled with water
- Modern barrier island: sandy unconsolidated material - just like beach sand - coarser grain sand
