AP Human Geography Unit 3 Overview

Sep 11, 2025

Overview

This lecture covers essential concepts from Unit 3 of AP Human Geography, focusing on culture, cultural landscapes, diffusion, language, religion, and the effects of cultural interaction.

Culture: Types & Characteristics

  • Culture is made up of material (physical objects) and non-material (beliefs, values) elements.
  • Subcultures exist within larger cultures, each with distinct practices.
  • Pop (modern) culture is diverse, individualistic, spreads rapidly, and evolves quickly.
  • Folk culture is traditional, collective, resistant to change, and spreads slowly.
  • Indigenous cultures are tied to specific regions, emphasizing tradition and community.
  • Ethnocentrism judges other cultures by one’s own standards; cultural relativism evaluates cultures by their own standards.

Cultural Landscape & Sense of Place

  • The cultural landscape consists of visible human impacts on the environment (architecture, land use, etc.).
  • Traditional, modern, and post-modern architectures reflect different cultural values.
  • Sequent occupancy shows how successive societies leave their mark over time.
  • Sense of place arises from unique cultural and physical characteristics; placelessness is a lack of such identity.
  • Placemaking involves communities transforming spaces for shared activities.

Regional Patterns & Forces

  • Regional patterns of language, religion, and ethnicity shape the cultural landscape.
  • Centripetal forces unite communities; centrifugal forces cause division.

Diffusion of Culture

  • Diffusion is the spread of cultural traits, people, or phenomena.
  • Relocation diffusion: physical movement of people spreads culture.
  • Expansion diffusion: culture spreads outward from a hearth and includes contagious, hierarchical, reverse hierarchical, and stimulus diffusion.
  • Historical causes include colonialism, imperialism, trade, and migration (e.g., creolization and diaspora).
  • Contemporary causes include globalization, technological advancements, and urbanization.

Religion

  • Universalizing religions (Christianity, Islam, Buddhism, Sikhism) seek to expand and appeal to all people, often spreading through expansion and relocation diffusion.
  • Ethnic religions (Hinduism, Judaism) are tied to specific groups/regions and mainly spread through relocation diffusion.

Language

  • Proto-languages are the earliest forms; language families share common ancestors.
  • Language branches and groups are subdivisions within families.
  • Dialects reflect regional language variations; isoglosses mark boundaries of language use.

Effects of Diffusion

  • Assimilation: minority cultures adopt dominant culture, often losing original identity.
  • Acculturation: cultures adopt traits from others but retain unique identity.
  • Syncretism: blending of different cultural traits into a new form.
  • Cultural resistance and barriers can hinder diffusion due to religion, language, or stereotypes.
  • Multiculturalism: coexistence of diverse cultures within a society (e.g., US, Canada).

Key Terms & Definitions

  • Material Culture β€” physical objects significant to a culture.
  • Non-material Culture β€” intangible beliefs, values, and customs.
  • Cultural Landscape β€” visible human alterations to the environment.
  • Sequent Occupancy β€” layers of cultural imprints over time in a place.
  • Centripetal Force β€” factor that unites people.
  • Centrifugal Force β€” factor that divides people.
  • Relocation Diffusion β€” spread of culture via physical movement.
  • Expansion Diffusion β€” spread through growing numbers in a region.
  • Stimulus Diffusion β€” core idea spreads but is adapted locally.
  • Creolization β€” blending of two cultures into a new one.
  • Diaspora β€” dispersion of people from their homeland.
  • Lingua Franca β€” common language for communication between speakers of different native languages.
  • Assimilation β€” minority culture absorbed by dominant culture.
  • Acculturation β€” adopting elements of another culture.
  • Syncretism β€” merging of different cultural traits.
  • Multiculturalism β€” coexistence of diverse cultural groups.
  • Isogloss β€” boundary of distinct language use.
