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.
Icebergs arâ¦e solid ice, and though the weight of  Titanic was considerable (46,000 tons), it was maybe a fifth of the  weight of the iceberg. Best case scenario would have been in which  the ship collided head on and ran a short way up onto the berg,  essentially beaching her.
