1. History: The study of past events, people, and societies.
2. Geography: The study of Earth's physical features, human populations, and the relationship between them.
3. Civics/Government: The study of citizenship, government systems, and political processes.
4. Economics: The study of how societies produce, distribute, and consume goods and services.
5. Sociology/Anthropology (often combined): The study of human social relationships and cultures. Sometimes these are treated separately, and sometimes other disciplines like psychology or archaeology might be included instead or in addition to these five.
It's important to note that social studies is interdisciplinary, meaning it often blends these fields to understand complex social issues.
