Is this a Fault- and Event-Tree Analysis base on the slides –   A fault-tree analysis is a method where the analyst starts with a risk event and looks for all possible causes of the event. This is diagrammed as a tree, with the risk event at the root and the causes extending away as branches. This analysis is used to discover all of the potential causes of the event (threats and threat actors in this case) so that they can be further analyzed for likelihood.  Similar to the fault tree, the event-tree analysis is also diagrammed as a tree structure but takes the opposite approach (bottom-up as opposed to top-down).

You estimate that the age of the ocean crust at the location you are studying is 10 million years old (10,000,000 yrs) and the average sedimentation rate for the basin is roughly 3 cm/1,000 yr.  How thick would the sediments at this location be in meters (m)? Remember that there are 100 cm per 1 m. You should not have any decimals for this question.
