Explanation:

- Acculturation: Refers to the process where individuals or groups from one culture come into contact with another culture and begin to adopt its practices and values. This doesn't necessarily mean the complete replacement of the original culture.

- Diffusion: Involves the spread of cultural elements such as ideas, styles, religions, and technologies from one culture to another. It emphasizes the movement of cultural aspects but not complete transformation.

- Assimilation: This is when individuals or groups fully adopt and integrate into another culture, often leading to the loss of their original cultural identity. It's a more complete cultural change.

- Socialization: The process by which individuals learn and adopt the norms and values of their society or culture. This is more about learning within one's own culture.
