Which term describes the process where individuals replace their home culture with a new culture?

The term that describes the process where individuals replace their home culture with a new culture is assimilation. Assimilation occurs when people adopt the cultural norms of a dominant or host culture, often to the extent that they lose their original cultural identity. This process can involve the absorption of language, customs, and social practices from the new culture, leading to a significant transformation of the individual's or group's cultural identity.

In contrast, the other terms refer to different processes. Acculturation involves the adaptation to a new culture while still retaining aspects of the original culture, meaning individuals may blend elements from both cultures without fully discarding their roots. Cultural diffusion describes the spread of cultural beliefs and social activities from one group to another rather than a direct personal transformation of cultural identity. Integration refers to the process of combining different groups or cultures within a society, allowing them to coexist and interact while maintaining their distinct identities. Thus, assimilation specifically focuses on replacing one culture with another, making it the most accurate term for this process.
