The Mormon culture can be observed in the outlying regions but would not be as prevalent as the core region. A cultural hearth is a source area in which a culture has become well established. Its characteristics are passed down to upcoming generations within and outside the primary hearth area. Examples of a cultural hearth for the Christian religion are the Middle East and Jerusalem. Christianity, among most religions, originated in this area and is therefore an overwhelmingly religious area.
Cultural diffusion is the effect that one society has on cultures surrounding it.
It is the movements of cultures to different parts of the world. A good example of this is the diffusion of European culture to the New World since the 1500's. The Western Hemisphere is predominantly Christian because of the movement of the Europeans eager to spread their Christian beliefs. The European World is noted for its aggressiveness. Field agriculture is a characteristic of the Europeans, with the use of mechanical implements in their fields.
