1. Why Study Geography?

  • We live on Earth — our environment affects us.
  • Explains interactions between natural resources, human activities, and technology.

  • Uses maps, GIS, and tools to interpret Earth.
  • Supports national development and sustainable planning.

2. What is Geography?

  • Geo = Earth, Graphos = Description (Greek origin).
  • Study of natural (mountains, rivers) and cultural (villages, cities) features.
  • Explores the relationship between physical and human environments.

3. Geography as a Study of Space

  • Focuses on spatial variation — differences across Earth’s surface.
  • Analyzes cause-effect of these differences.
  • Example: Cropping patterns vary due to soil, climate, technology, economy.

4. Nature and Human Interaction

  • Primitive societies directly depended on nature.
  • Modern societies use technology to adapt or modify nature.
  • Humanised Nature: Nature influenced by humans.
  • Naturalised Humans: Humans shaped by nature.

5. Geography as Spatial Science

  • Focuses on spatial organisation and integration of phenomena.

7. Geography and History

  • Geography influences historical events and movements.
  • Examples: Himalayas protected India; sea routes led to trade and colonisation.

8. Geography and Time

  • Time is considered the 4th dimension in geography.
  • Example: 1500 km = 2 hrs by flight or 17 hrs by train.
  • Every spatial change is also temporal.

9. Branches of Geography
