Culture consists of three main components: 1) a diverse pool of shared knowledge, realities, norms and meanings; 2) aspects that are learned and transmitted between generations; and 3) facilitates survival and adaptation. Culture can be represented by an iceberg, with most aspects below the surface being implicit and harder to observe than explicit surface level aspects. Examples are given of differing concepts of beauty across cultures, such as foot binding in China, and acceptable behaviors like slurping noodles in Japan that may seem strange to outsiders but are part of the local culture below the surface.
