Explanation:

- Acculturation: This is when individuals or groups from one culture come into contact with another culture and adopt some aspects of that culture. It usually involves a mix of cultural exchange but not total blending into one.

- Integration: This is when different cultural groups maintain their distinct identities while coexisting within the same environment, often leading to a multicultural society.

- Amalgamation: This occurs when multiple cultures come together to create a new, unique culture, often seen in new societies formed through immigration.

- Assimilation: This is the process in which one group gradually adopts the cultural traits of another until both groups become indistinguishable from one another.
