What is the difference between a metaphor, personification and a simile?

see below
Simile, metaphor, hyperbole, and personification are all figures of speech.
Simile compares one thing with another thing that is of a different kind. It uses “like” or “as” to compare.
Ex:
She is as blithe as a lark.
Your words are like balm to my aching heart.
Metaphor is similar to simile, except that it does not make use of words “like” or “as” to compare.
Ex:
The living room was a war zone after the boys left.
The new leader rules with an iron hand.
Personification attributes human character to something that is nonhuman.
Ex:
The trees lift their arms to heaven.
The earth devoured the houses as the earthquake shook the entire city
