What Is Geography?
Geography is the study of the physical features of the Earth, including how humans affect
the Earth and are affected by it. Geography deals with physical aspects of the Earth: the
composition, the layers of the Earth, the atmosphere, the plants and animals, mountains,
rivers, and other landforms. But it also analyzes how humans have affected those physical
features and how the arrangement of those features has affected humans. Why do humans
settle where they do? How do humans impact the environment? How do the physical
landscapes create human conflict? All of these things are covered by geography.
Since geography is such a large subject, with so many topics, it makes sense to split it into
key themes. Today, we're going to briefly discuss the five main themes of geography.
The Five Themes
There are five main themes of geography: location, place, human-environment interaction,
movement, and region. Collectively, these five themes encompass the whole of the subject of
geography.
 Location is kind of like the first step in understanding an aspect of the Earth and
involves providing a reference to describe where a particular place is on the Earth.
This could be an absolute location, where a location is based on a definitive reference
that rarely changes, such as latitude or longitude, or an address. Or it could be a
relative location, where a place is described relative to its environment or its
connection to other places.
 Place is a description of the physical and human characteristics of the location being
studied. This could involve describing the mountains, valleys, rivers, beaches, and the
living organisms that inhabit it. It also includes human features, like land-use,
infrastructure, and communications.

Region is about classifying the parts of the world. We humans love to draw borders
and put names, labels, and categories on things, even when those borders and labels
are mostly made-up. Region considers how the land is split up into continents, regions,
countries, counties, states, and cities.
 Movement involves describing and discussing the effects of anything that moves
across the Earth. Very often, this is related to humans: movement of humans
themselves, goods, services, immigration, and so-forth. The migration of animals can
play a part, especially when looking at changes in a landscape over long periods of
time.
 Human-environment interaction is the study of how humans affect the environment
and how the environment affects humans. Humans can have positive impacts on the
environment or negative ones. And we can even disagree about whether an impact is
positive or negative. Human geography is a complex and varied topic in itself.
