Culture refers to the characteristics and knowledge of a particular group of people, including their language, religion, cuisine, social habits, music and art. It is shared and transmitted between members of a group. A culture represents the beliefs and practices of a society, while society represents the people who share those beliefs and practices. Culture consists of both material aspects like objects and structures, as well as nonmaterial aspects like ideas, attitudes, and beliefs. Culture plays an important role in human societies by defining groups and contributing to how people interact and organize. Cultural change can occur due to factors like technological changes, environmental changes, new ideas, and the diffusion of customs between groups.
