Meaning and Definition of Geography

NCERT Pages: 2–3

These notes explain the meaning and origin of the term geography.

Geography

  • Geography studies the Earth as the home of human beings.
  • It studies physical and cultural features on Earth’s surface.

Word Origin

Word Meaning
Geo Earth
Graphos Description
Important Fact: The term Geography was first coined by Eratosthenes.

Important Scholars

Scholar Contribution
Eratosthenes Coined term Geography
Richard Hartshorne Geography studies areal differentiation
Hettner Studied differences of phenomena

Geography as Description of Earth

NCERT Pages: 2–3

  • Geography explains mountains, plains, rivers and oceans.
  • It also studies cities, roads, railways and settlements.
  • Geography studies both natural and cultural phenomena.

Areal Differentiation

NCERT Page: 3

Physical and cultural features vary from place to place. Geography studies these spatial variations.

Examples

Phenomenon Cause of Variation
Cropping pattern Soil, climate, market
Population density Resources and economy
Settlements Relief and transport
Important Fact: Geography studies cause-effect relationships.

Geography and Cause-Effect Relationship

NCERT Pages: 3–4

Geography explains why phenomena occur, where they occur and how they are related.

Three Major Questions in Geography

Question Meaning
What? Identification of features
Where? Distribution of features
Why? Cause-effect relationship
Important Fact: “Why” question makes geography scientific.

Human-Environment Relationship

NCERT Page: 3

  • Humans are integral parts of nature.
  • Nature influences food, clothing, shelter and occupation.

Human Responses

Human Response Example
Adaptation Living according to climate
Modification Technology-based changes
Important Fact: Technology reduced dependence on physical environment.

Geography as Spatial Organisation

NCERT Pages: 3–4

  • Human activities organise space through transportation, communication and settlements.

Important Terms

Term Meaning
Nodes Settlements
Links Routes and networks

Geography as an Integrating Discipline

NCERT Page: 4

  • Geography integrates natural and social sciences.
  • It studies interdependence among phenomena.
  • Geography attempts spatial synthesis.

Geography and Other Disciplines

Natural Sciences Social Sciences
Geology Economics
Meteorology Sociology
Oceanography Political Science
Botany Anthropology

Spatial and Temporal Synthesis

NCERT Pages: 4–6

Discipline Focus
Geography Spatial synthesis
History Temporal synthesis
Important Fact: Time is considered the fourth dimension in geography.

Approaches to Study Geography

NCERT Page: 6

Systematic Approach

  • Studies one phenomenon worldwide.
  • Example: Natural vegetation studied globally.
Scholar Contribution
Alexander Von Humboldt Systematic geography

Regional Approach

  • Studies all geographical phenomena within a region.
Region Type Example
Natural Himalayan region
Political India
Designated Planning regions
Scholar Contribution
Karl Ritter Regional geography

Dualism in Geography

NCERT Page: 6

Division Focus
Physical Geography Natural features
Human Geography Human activities
Important Fact: Human geography developed due to cultural activities.
