Final answer:
Special ceremonies that mark significant life transitions, such as graduation or marriage, are called rites of passage, involving stages of separation, liminality, and incorporation.
Step-by-step explanation:
Special events that mark the transition from one role to another, such as bar mitzvah, confirmation, graduation ceremony, or wedding, are known as rites of passage. These ceremonies signify social transformations in individuals' lives, such as birth, puberty, marriage, and death, and are characterized by three stages: separation, transition (or liminality), and incorporation.
During these rites, individuals often receive instruction and support from mentors or guides, and the ceremonies can involve both religious and secular elements.
