It IS inconsistent with a rapid deposit. The depth isn't correlated with density, or weight or buoyancy. Instead it's correlated with complexity. Organisms survive because they are still well adapted to their environment. Anyone with the slightest education in evolution would be able to answer that. Also, a few strata have isotopes that aren't found on earth anywhere else, but are found on meteors, and these strata perfectly partition fossil - just as if a large meteor broke up in the atmosphere and was distributed over a large area, somewhere between two ages with different animals. This is completely inconsistent with all the strata being deposited at once. Not to mention we have a very good idea of the rate of sediment deposits which is consistent with the estimated ages of the fossil records. Also consistent with documented volcanoe eruptions which have caused identifiable deposits. Also, the types of plankton and krill have changed over time in ways that leave different variants in different strata, but inconsistent with a sudden deposit, since these species all were essentially the same, and wouldn't be expected to differ in buoyancy. That's just off the top of my head - and I'm no expert. If you want to attack the science, at least learn some of it first.
