Final answer:
Cultural assimilation is the process where minority groups adopt characteristics of the dominant culture, which has been a significant aspect of U.S. history, particularly during periods of high immigration.
Step-by-step explanation:
The term that describes the process by which a minority individual or group abandons its own identity to take on the characteristics of the dominant culture, such as by absorbing immigrants from different lands, is cultural assimilation. This process often involves acculturation, where minority individuals adapt to the beliefs and practices of the larger group, potentially through intermarriage, language assimilation, and socioeconomic changes. Unfortunately, challenges such as racial and ethnic discrimination can make full assimilation difficult, erecting barriers to aspects of life like employment and education.
