The answer is: The personification makes the setting more vivid to the reader.
Figurative language is a nonliteral, metaphorical or symbolic choice of words, and personification occurs when something nonhuman possesses human qualities, or when an abstract attribute takes human shape.
In the passage from "Morte d'Arthur," by Alfred Lord Tennyson, personification is used to offer readers a more forceful or powerful description of the scene. For example, <em>mighty bones, the wind-sea sang shrill</em> and <em>flakes of foam.</em>
Apple is to tree as grape is to vine.
Hair = simile
apples = generalization
