What is cultural diffusion? how can the west be seen as a crossroads of culture

Cultural diffusion is the spread of beliefs and social activities of different cultures, ethnicities, regions, etc. This can be shown a lot in the west, but America is a good example. The country is widely diverse, and for example places like New Orleans show lots of mixing with other cultures (French cuisine, architecture, etc in New Orleans).

Cultural diffusion is the spread of cultural beliefs and social activities from one group of people to another.
