How do you tell the difference between folk and pop culture?

Folk culture is characterized by traditional practices, customs, and expressions that are often passed down through generations within a specific community or region, reflecting its unique identity. In contrast, pop culture refers to contemporary trends, styles, and entertainment that are widely consumed and promoted through mass media, often transcending geographical and cultural boundaries. While folk culture tends to be grassroots and localized, pop culture is typically more commercialized and globally pervasive.
