What is geography? A detailed introduction.
Geography is a key discipline of earth science that studies physical features, natural processes, population, the environment, and human relationships. Geography is an interdisciplinary field that combines parts of the scientific sciences, social sciences, and humanities to better comprehend the Earth’s landscapes, habitats, and the processes that shape them.
We can further divide geography into two major branches.
Physical geography is the study of the earth’s natural properties and processes. Physical features may include landforms, climate, weather, and ecosystems, whereas physical processes may consist of the factors that influence these features and change the planet’s surface. Physical geographers investigate plate tectonics, erosion, climate change, and natural disasters.
Human geography is the study of how human actions interact with Earth’s physical and natural characteristics and processes. It covers subjects such as population, migration, urbanization, cultural landscapes, economic activity, rural and urban development, and political borders. Human geographers study how people interact and create the environments in which they live.
Definitions of geography by various scholars and specialists.
Because geography is a complicated field, numerous experts and researchers have developed their own definitions over time. Let’s look at a few definitions from some famous geographers:
Immanuel Kant, a renowned German philosopher, described geography as “the science of the Earth as the abode of human beings.” He highlighted human activities in this home, as well as the link between people and their surroundings.
German geographer Carl Ritter, widely recognized as the pioneer of modern geography, defined geography as “the science of the Earth about natural features and man.”
Richard Hartshorne, a prominent American earth scientist, described geography as “the study of the Earth as the home of people.” His definition centers on the human-environment interaction.
Paul Vidal de la Blache, a French geographer, defined geography as “the science of places and the relationships between people and their environments.” Vidal de la Blanche’s work influenced the creation of modern human geography.
William D. Pattison is a famous US Navy sailor and winner of the Navy Cross. William D. Pattison was well-versed in the earth sciences. In his seminal work “The Four Traditions of Geography” (1964), he asserted that four traditions comprise geography: earth science, culture-environment, location, and area analysis. Each of these traditions addresses geography in a somewhat different way.
Yi-Fu Tuan was a famous cultural geographer. He described geography as “the study of how people make sense of their world.” He studies the perceptual and cognitive elements of human-environment interactions.
David Harvey, a British economic geographer, described geography as the interaction of economic and social actions with geographic patterns. He describes geography as “an outcome of human activities.”
The above-mentioned definitions, established by various scholars, demonstrate the changing nature of geography and the variety of perspectives within the field. While some focus on the Earth’s physical aspects, others stress the human and societal dimensions. Geography is a dynamic discipline with a diverse set of ideas and approaches.
Branches of Geography
In the preceding lines, we divided geography into two branches: physical geography and human geography. We can divide each branch into numerous subfields.
1. Physical geography.
Physical geography is a core subject of geography that studies the physical features and processes on the Earth’s surface. It covers a variety of themes and disciplines, including:
Climatology is a discipline of physical geography that examines Earth’s climate, including long-term weather trends, climate classification, and climate-influencing elements such as air circulation, ocean currents, and greenhouse gas emissions.
Geomorphology is the study of the earth’s landforms and the processes that shape them, such as erosion, weathering, and tectonic activity.
The study of Earth’s water systems, including the distribution and movement of water worldwide, is known as hydrology. It discusses rivers, lakes, groundwater, and the water cycle.
Glaciology is the study of glaciers and ice sheets, including how they develop, travel, and affect the terrain. It is critical for understanding historical and current climate conditions.
Biogeography studies the distribution of living species on Earth and the variables that impact it. This encompasses ecosystems, biodiversity, and how human actions affect natural habitats.
Pedology (Soil Science) is the study of soil, including its creation, categorization, and qualities. It is critical to understanding agriculture, land use, and environmental quality.
Oceanography is the study of Earth’s oceans and seas, encompassing their physical, chemical, and biological components. It includes the study of ocean currents, marine life, and the effects of human activity on marine habitats.
Astronomical geography is the study of celestial bodies and their influence on Earth. It covers topics such as the Earth’s position in the solar system, astronomical cycles, and their global impact.
Environmental geography studies the relationships between human society and the natural environment. It investigates environmental conservation, resource management, and the effects of human activity on ecosystems.
Volcanology is the study of volcanoes, eruptions, and volcanic landforms. Its goal is to understand volcanic processes and assess volcanic threats.
Seismology is the study of earthquakes and the earth’s interior structure. It entails tracking and analyzing seismic waves to better understand the Earth’s composition and earthquake origins.
Atmospheric Science (Meteorology): Forecasting, weather systems, and atmospheric phenomena are the main areas of focus for meteorology, despite its close relationship to climatology.
2. Human Geography.
Human geography, like physical geography, is a subfield of geography that studies human civilizations, their interactions with the environment, and the spatial distribution of various human phenomena rather than natural phenomena on Earth. Human geography is divided into multiple subfields or divisions that study various aspects of human activity and their relationship to the physical world.
Some major branches of human geography include:
Cultural geography studies the distribution and spatial patterns of distinct cultural activities, beliefs, languages, and traditions. It explores the ways in which the physical environment shapes and influences culture.
The study of economic geography examines the spatial distribution of economic activities such as agriculture, industry, trade, and services. It examines the impact of economic systems, globalization, and economic development across regions.
Urban geography is the study of cities and urban regions, including their growth, organization, and the social, economic, and environmental challenges that accompany urbanization.
Political geography is the study of political entities’ spatial distribution and boundaries, as well as how geography influences political processes and geopolitical conflicts.
The study of population geography examines the distribution, growth, and movement of human populations. It covers topics including population density, migration, urbanization, and demographic trends.
Social geography investigates the spatial distribution of social groups and communities, as well as the effects of social structures, identities, and inequality on various physical places.
Environmental geography examines the link between humans and the natural environment. It investigates issues such as environmental deterioration, conservation, and human impact on ecosystems.
Health geography investigates the spatial distribution of health-related elements such as disease outbreaks, access to healthcare, and the environmental influence on human health.
Tourism geography is the study of the spatial aspects of tourism, such as tourist destination locations, tourism’s impact on local economies and cultures, and tourism’s environmental repercussions.
Rural geography is the study of rural landscapes, agriculture, and rural communities’ social and economic dynamics.
Transportation geography is the study of the spatial distribution and organization of transportation systems such as roads, railroads, airports, and ports, as well as their impact on regional development and accessibility.
Historical geography examines how historical events and human activity have impacted the current landscape.
These subfields of human geography are so closely related that they frequently overlap and cross, and scholars in this discipline often use interdisciplinary approaches to comprehend the complex relationships between people and their surroundings.
