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.
The Titanic hit the iceberg at 11:40pm on April 14, 1912 and roughly two hours and forty minutes later at 2:20am on April 15th the ship plunged to the bottom of the ocean.
