Geography: The Study of Earth and Its Phenomena

Introduction to Geography

• The word 'geography' comes from the Greek words 'ge' meaning 'earth' and 'graphia' meaning 'description'
• Geography seeks to understand the physical features of the earth and the human societies that inhabit it
• In planetary science, geography is significant because it helps understand the earth as a whole system

History of Geography

• The first recorded user of the word 'γεωγραφία' (geographia) was Eratosthenes in 276 BC
• The earliest attempts to understand the world spatially, including cartography, occurred around 6000 years ago

Core Concepts and Branches

• The core concepts of geography consistent between all approaches include location, place, human-environment interaction, movement, and region
• The three main branches of geography as a discipline are human geography, physical geography, and technical geography
• Human geography focuses on the study of human populations and their relationship with the environment
• Physical geography focuses on the study of natural features and processes of the earth
• Technical geography involves the use of technology such as GIS and remote sensing to study the earth

Approaches and Techniques

• The two approaches employed in the discipline of geography are spatial analysis and area studies
• Common techniques employed in geography include mapping, spatial analysis, and fieldwork
• The interdisciplinary nature of geography means it draws from other disciplines such as sociology, anthropology, and biology

Goals and Description of the World

• The main preoccupation of geographers is to understand the complex relationships between human and natural systems
• Geography seeks to describe the world as a complex system of interconnected human and natural phenomena

Explore the discipline of geography, which encompasses the study of Earth's lands, features, inhabitants, and natural complexities. Gain insight into how geographical phenomena have evolved and come into existence, and how these concepts can be applied to other celestial bodies in planetary science.
