Final answer:
Mores are essential to the well-being of society, embodying moral views and having serious consequences if breached, in contrast to the less consequential folkways that handle everyday cultural expressions.
Step-by-step explanation:
Unlike folkways, mores are essential to the well-being of society. Mores are norms that embody the moral views and principles of a group, having serious consequences if violated. They are protected with laws or judged by public sentiment, providing a foundation for acceptable behavior and societal function. In contrast, folkways direct appropriate behavior in the more mundane aspects of a culture without any moral underpinnings, indicating day-to-day practices and expressions of a culture, such as how to greet someone or what to wear to an event.
The biggest difference between mores and folkways is that mores are linked to morality and have serious consequences when breached, while folkways are tied to commonplace behaviors without such grave implications. The norms and consequences associated with violating mores can be as extreme as expulsion from school for plagiarism in the U.S. school system, demonstrating their high significance.
