Culture is more deeply-rooted and interconnected with our sense of identity and self-understanding than people often imagine. Thinking about what we can see and understand of a culture not our own is similar to the way we perceive an iceberg. Indeed, the same thing may be true even of what we understand to be our own culture. We may not even be aware of how our culture dominates our value system and shapes our view of life, our interpersonal relationships, and other aspects of daily life.
Think of the iceberg. Though logic tells us we are only seeing a very small portion of an iceberg above water, it's still hard to imagine that we are seeing such a small part of it. Indeed, almost 92% of an iceberg lies below the surface of the water. The first known use of an iceberg as an analogy to explain the concept of culture was by Edward T. Hall in 1976.
Other analogies or metaphors for culture have included an onion, a pot of flower plants and even a fish swimming in water

A concentric circle diagram illustrates how worldview is foundational to beliefs, and how beliefs are then foundational to values, and how values drive behavior. Lloyd Kwast explains his diagram:
One helpful method to view a culture [is to visualize] several successive layers or levels of understanding as one [moves from observable behavior] into the real heart of the culture.
Values in a culture are not selected arbitrarily, but invariably reflect an underlying system of beliefs. . .
At the very heart of any culture is its world view. . . Sometimes people who share the gospel cross-culturally fail to take the problem of worldview into account and are therefore disappointed by the lack of genuine change their efforts produce.

To be sure, Lloyd Kwast's model of culture is, as Kwast himself admits, "far too simple to explain the multitude of complex components and relationships that exist in every culture." It can, however, be a beginning point.
The image of an onion is often used to describe the different layers of culture. The outer layers are the artefacts and products as well as patterns of behaviour. The next layer encompasses the beliefs, norms, and attitudes of that culture. The middle of the onion represents the underlying cultural assumptions and values.
Gerard Hendrik Hofstede created the model of the Cultural Onion. It is made of layers around a core like an onion. The core stands for the values of a certain culture, which is not moving a lot. It mostly remains the same. Even if something seems to be outdated, it still can subconsciously play a role in the present. The first layer around the core is that of rituals or patterns wedded to that culture. Those rituals change only slowly. On another layer are the "heroes." These can be either real or fictional people. They both reflect and influence the beliefs, norms and attitudes of that culture. On the outside are the symbols and actions in momentary fashion in the culture. All the layers can be modified, re-trained, and re-learned. The core -- the inner values and assumptions of the culture -- is different.
