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.
Roughly 2 hours and 42 minutes: Titanic struck the iceberg at 11:40pm on the 14th April and sank at 2:20am the next day. When the Titanic hit the iceberg the bottom four floors started flooding and it kept on going until the whole ship split in half and sunk to the bottom of the sea where it split once more into three pieces when it hit the bottom.
