Bottom-up processing is not thought to be a very efficient way to approach a text initially, and is often contrasted with top-down processing, which is thought to be more efficient. Example. Asking learners to read aloud may encourage bottom-up processing because they focus on word forms, not meaning.
Had Titanic hit the iceberg head on, it is likely that there would be massive crushing of the fore part of the ship, which may have prolonged its end, since theoretically while it may have begun to go down by the bow, the center and aft compartments would have stayed dry for a longer period of time.
Minutes later the Titanic struck the iceberg.  By 2:20 am on April 15, just two hours and forty minutes later the Titanic had sank below the icy waters of the North Atlantic. More than 1500 passengers and crew lost their lives. Only 700 survived.
