The document describes different elements used in a nature documentary and their effects on the audience. It explains that David Attenborough's narration informs viewers about what is happening on screen. Added sound effects of sand moving, while not recorded on location, prevent audience confusion by providing realistic noises. Background music makes scenes seem more cheerful and relaxed for audiences, while more comical music cues viewers into finding a large crab switching shells to be a funny moment.
