Final answer:
Shakespeare uses imagery and symbolism to depict changes in nature and explores the enduring power of love in preserving the relationship between Romeo and Juliet.
Step-by-step explanation:
Shakespeare transitions between changes in nature in Romeo and Juliet through the use of imagery and symbolism. He often associates the changing of seasons and natural elements with the emotions and events of the characters. For example, in the balcony scene, Romeo compares Juliet to a beautiful summer's day, emphasizing her loveliness and the fleeting nature of their love. In terms of preserving their love, Shakespeare explores the power of love to transcend societal obstacles and even death itself. Despite the tragic ending, Romeo and Juliet's love is portrayed as enduring and powerful.
