Geography is about studying places and how everything on Earth is organized. It explores landforms, weather, people, and where natural and human-made features are found.
Physical geography focuses on the natural features of Earth. It explains how these features form, change, and connect with each other. Unlike human geography, it doesn’t study borders or cities but does look at how people impact nature.
Since physical geography is a wide subject, geographers study it through six main branches: geomorphology, pedology, biogeography, hydrology, meteorology, and climatology.
Major Branches of Physical Geography
What is Physical Geography? Key Specializations Explained Simply
Physical geography helps us understand Earth’s natural features and how they change. It covers many interesting topics. Here are six important specializations in this field:
- Geomorphology – This branch studies landforms like mountains, valleys, and plains. It explores how natural forces like earthquakes, volcanoes, and erosion shape the Earth’s surface over time.
- Pedology – This is the study of soil. Scientists look at what soil is made of, how it forms, and how to protect it from erosion or damage. It’s important for farming and the environment.
- Biogeography – This field focuses on where plants and animals live. It helps us understand ecosystems, animal migration, and how nature changes over time.
- Hydrology – Hydrology looks at water in all its forms—rivers, lakes, oceans, and even underground water. It also studies how water moves and affects the land.
- Meteorology – While it’s a separate science, meteorology often overlaps with physical geography. It studies daily weather like rain, wind, and storms.
- Climatology – Climatology is about long-term weather patterns. It helps us understand climate change, rainfall, and temperature trends around the world.
These specializations all help answer the question: What is physical geography, and why is it important to study Earth’s natural systems?
The Journey of Physical Geography Through History
Physical geography has deep roots, dating back to the classical Greek period when geography was primarily seen as a natural science. Early pioneers like Strabo, Eratosthenes, and Dionysius Periegetes focused on describing the known world. By the 16th century, works like Martín Fernández de Enciso’s “Summa de Geografía” marked a turning point by introducing the concept of the New World.
In the 18th and 19th centuries, debates between James Hutton’s uniformitarianism and Georges Cuvier’s catastrophism shaped geography’s evolution. During this time, Alexander von Humboldt’s “Kosmos” highlighted geography as a natural science.
The 19th-century colonial expansion and the Industrial Revolution further transformed geography, leading to the establishment of university geography departments and national geographic societies, making geography an institutionalized discipline.
The exploration of Siberia in the mid-18th century played a key role in the growth of physical geography. Russian geographer Mikhail Lomonosov, often called the “father of Russian geography,” led many significant studies during this time. While working at the Department of Geography, Academy of Sciences, he explored Arctic Siberia, proved the organic origin of soil, and formulated a law on ice movement, which laid the foundation for glaciology. In 1755, Lomonosov established Moscow University, where he promoted geography education, and by 1758, as director of the Academy’s Department of Geography, he organized major surveys and expeditions.
Lomonosov’s students further expanded Russian geography in the 19th century. Vasily Dokuchaev introduced the concept of soil as a separate geographic element, creating pedology. At the same time, Wladimir Köppen developed the famous climate classification system, still used globally, and pioneered palaeoclimatology through his research on ancient climates. Other notable contributors included NM Sibirtsev, Pyotr Semyonov, and K.D. Glinka.

In the late 19th and early 20th centuries, William Morris Davis, often called the “Father of American Geography,” transformed physical geography with his cycle of erosion theory. Davis proposed that mountains and landscapes evolve through a natural cycle: they begin with uplift caused by tectonic forces (youth stage), followed by erosion that carves deep V‑shaped valleys (maturity stage), and eventually flatten into peneplains or “almost plains” (senescence stage). Over time, rivers rejuvenate, and the cycle begins again.
While modern science has shown that Davis’s theory isn’t fully accurate, it was groundbreaking for its time. It laid the foundation for geomorphology, a new subfield of physical geography dedicated to studying landforms and their evolution. His work also influenced other disciplines like paleogeography, hydrology, and climatology by providing a framework for understanding landscape changes over time. His students, including Curtis Marbut and Mark Jefferson, expanded his ideas into areas like pedology and landform mapping.

Stages of Davis’s Cycle of Erosion
| Stage | Key Features | Landform Example |
|---|---|---|
| Youth | Uplifted mountains, steep slopes, V‑shaped valleys | The Himalayas (early stage) |
| Maturity | Valleys widen, rivers start meandering | Appalachian Mountains (middle) |
| Senescence | Flat plains (peneplain), minimal elevation | Old eroded surfaces, e.g., plains in Africa |
Interesting Fact: William Morris Davis’s cycle theory was so influential that it became the first global model of landscape evolution, inspiring geographers for decades.
