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.
When the ship struck the iceberg, six of those compartments were damaged and the ship began to take on water very rapidly. When did the Titanic sink? The ship struck a massive iceberg late on the night of April 14, 1912. It took approximately 3 hours for the entire ship to sink. The Titanic became completely submerged about 2:45 AM on the morning of April 15, 1912.
