While we are (for those that accept the Bible is inspired by a Being that knows all things and also the entire past & future) listening to the words of God, they are being conveyed through the eyes and thoughts and language of people between 1500BC and 100AD.
So while you or I if we saw a meteorite would use the word meteorite, unfortunately that word (for example) wasn't available to John who wrote the book of Revelation; so when John is given a vision (to write down) about a scene that relates to his and our future, he says he saw a burning mountain fall into the sea! We in turn have to try and see it through his eyes/ mind to know what he means.
