Geography degrees, as our guide explains, are some of the most varied out there. In fact, perhaps it's more apt to consider it as a field rather than a subject. Ever seen a strange rock formation and wondered how it got that way? Or watched a documentary about an overcrowded slum and wanted to understand why people were living in such poor conditions? Studying geography at university should cover all this, and much, much more. Both of these situations could fall within the bounds of a geography degree, though the first would be categorized as physical geography and the second as human geography. These are the two major sub-disciplines when studying geography at university, and in fact the two branches are very different. Human geography is concerned with the study of human societies – how they operate, develop, and the challenges they face. So you could look at issues such as population change, cultural and religious practices, or globalization. Physical geography, on the other hand, is about understanding the earth’s physical processes – from climates and weather systems, to earthquakes and rock formations, right down to what’s happening on the ocean floor. Some universities will offer a choice between a Bachelor of Arts (more of a human geography focus) or Bachelor of Science (physical geography). But even so, it’s usual to start by taking some introductory modules in both sides of the subject. Find the world's best universities for geography with the QS Rankings by Subject >

If you want to make a difference to the world, a degree in geography is a good place to start. Depending on your specialization, you could be involved in developing solutions to some of the most pressing problems for modern society: climate change, natural disasters, overpopulation, urban expansion, multicultural integration. Geography graduates may provide research and advice to help governments, charities or other organizations – either working directly for a particular organization, or as part of an independent research group, think tank or university faculty. Other roles could include cartography (producing maps), transportation management, town planning, and environmental and conservation work. A geography degree also provides many transferable skills – including data analysis, report writing and computer modelling – which could support careers in a wide range of sectors.
