Step-by-step explanation:
The simile 'waves rising up like mountains' in the book 'The Seventh Man' is significant because it vividly conveys the immense power and overwhelming nature of the waves that the characters are facing. This simile is used to illustrate the monumental struggle and the minuscule chances of survival against the formidable forces of nature.
