The presence of mosques in the united states is an example of how a country’s culture can be modified through

Diffusion

Explanation:

When people from different societies come in contact with each other, there is every possibility that there would be a diffusion of ideas, beliefs, structures, and other elements of their cultures. Sometimes, elements of a culture are assimilated by the host society. Diffusion in this instance is the movement of any aspects of culture from a region where it is widely accepted to a region where little about it is known.

The United States culture is dominantly Christian. The presence of a mosque is the diffusion of the Islamic religion to the predominantly Christian religion.
