Explanation:Ethnocentrism refers to how we tend to believe that our own culture is superior and much better than that of others , and as a result we use our own cultural values or norms or customs to judge other cultures as inferior and not good as ours. This means we use our own culture as a standard to measure other cultures anything that doesn't fall within our own culture we consider it to be devious , unnantural and wrong.

cultural relativism refers to how we believe that other beliefs ,values and practices should be acknowledged based on those individual's culture rather than suing our own cultures as a standard measure of someone else's culture

So cultural relativism accept that cultures are different with all its values and practices and that should be understood and not be judged on basis of other cultures.
