Social change is the process by which a society changes over time. It can be caused by a variety of factors, including technological advances, economic changes, political changes, and cultural changes.

Biological change is not a type of social change. Social change refers to changes in the way people live and interact with each other, while biological change refers to changes in the physical characteristics of a population.

Social differentiation is the process by which a society becomes more complex and organized. It involves the development of different social roles and statuses, as well as the emergence of new institutions and organizations.

Social stratification is the process by which a society becomes more unequal. It involves the development of different social classes and the emergence of a hierarchy of power and privilege.

Social mobility is the process by which people move from one social class to another. It can be either upward or downward mobility.

Social integration is the process by which people from different social groups come together and form a new, more integrated society. It involves the development of shared values, norms, and institutions.

Social pluralism is the process by which a society becomes more diverse. It involves the coexistence of different cultures, religions, and ethnic groups within a single society.

Social conflict is the process by which a society becomes more conflict-ridden. It involves the emergence of competing interests and values, as well as the use of violence or other forms of coercion to resolve conflicts.

Natural disasters are not a factor that can contribute to social change. Social change is caused by human actions and decisions, not by natural events.

New technologies are not a consequence of social change. They are a factor that can contribute to social change.

The evolutionary theory is not a theory of social change. It is a theory of biological evolution.

Experimental research is not a method for studying social change. It is a method for testing hypotheses about cause-and-effect relationships.

The discovery of a new planet is not an example of social change. It is a scientific discovery.

Natural disasters are not a challenge to social change. They are a factor that can contribute to social change.

Violence is not a way to promote social change. It is a destructive force that can lead to more conflict and suffering.
