The rhyme scheme of the poem is—a b a a, b c b c b

This rhyme scheme helps in bringing out the contrasting ideas of ‘fire’ and ‘ice’ presented in the poem. The poet mentions that both fire and ice are probable ends of this world. He talks about how fire represents desire and can therefore be a cause of the end of the world. Frost also mentions ice to symbolize that the coldness and indifference towards one another will also be enough to end the world. In the second stanza, he says that he knows of enough hate in the world to be sure that even destruction through ice . would be sufficient to bring about the end of the world.
