Final answer:
Race involves physical differences, while ethnicity refers to differences in culture.
Step-by-step explanation:
The term race refers to superficial physical differences that a particular society considers significant. Examples of physical differences include skin color, hair texture, and facial features. On the other hand, ethnicity describes shared culture and includes aspects such as language, religion, customs, and traditions. It is important to note that while race is primarily based on physical characteristics, ethnicity is based on cultural factors.
