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.
On the night of the collision, because the moon was not out, and the water was so still, it was very difficult to see the iceberg. A less calm water would have caused breakers around the iceberg making it easier to see it from afar. The iceberg that the Titanic struck was not a very big one. It did not even come up as high as the bridge of the ship. The iceberg that the Titanic struck was unusual in such a way that it was not white like most others, but more of a clear look caused by continuous melting.
