Final answer:
The term that describes norms and values shared across cultures globally is 'global culture'. This concept signifies the shared beliefs, values, and practices, and globalization has allowed these aspects to spread internationally, impacting multiple societies.
Step-by-step explanation:
The term that describes norms and values that extend across national boundaries and are shared by multiple cultures is known as global culture. This concept encapsulates the spread of shared beliefs, values, and practices, which create a common cultural ground among different societies and nations. With globalization, goods, symbols, and ideals from one country can become influential worldwide, as seen with the international recognition of brands such as Levi's and McDonald's. These entities serve as vehicles for disseminating the originating country's cultural values. People within a shared culture enforce and create expectations for behavior, and sociologists study these norms to understand how individuals conduct themselves within various social contexts. These norms often become apparent when compared with the values and practices of other cultures, such as the interpretation of physical gestures or the appropriateness of certain behaviors in public. Culture is a powerful force that shapes how individuals perceive the world and interact within it, demonstrating that while cultures can differ, they can also converge and influence one another on a global scale.
