Race has to do with physical appearances, such as skin color or hair type. Ethnicity has to do with culture, a group of people with shared meanings, foods, languages, etc.
The difference between Race and Ethnicity is that usually Race is assosiated with being deragatory. Being of negative origin and its usually unorthodox while Ethnicity relates to actually litigated terms. Basically ethnicity is a formal more positive way to catagorize different persons and their particular colours.
Ok so i know you probably didn't understand a single word i said in the beginning so let me generalize it for you.
Race is in a sense negative. People usually refer to it when they say racist or other negative words. Race is more of a peoples way of catagorizing people and their colors. As such it is more negative term of it. An example of this is when they decided to call African Americans/ horrible slang words such as Black people. Or the n word. These are basically the bad terms associated with the peoples of sed colors.
Ethnicity is a more formal way of catagorizing people based on their skin colors and place of origin. Unlike race which is defined by slang and skin color solely ethnicity tends to generalize by instead including place of origin as a key factor. Thus making it more formal and less...racist.
In summary Ethnicity is a more formal way of identifying people by color and origin while race is more of a non formal approach to identifying people by color.
Be warned because i may be wrong but im pretty sure this is the answer.
