Welcome to Physical Geography! Geography is an exciting subject that focuses on the spatial distribution of natural phenomena and the interaction of humans with the natural world. Geography is much, much more than simply memorizing the names of state capitals and major rivers. Geography looks to explain and understand the natural world that we live in. The four major questions that every geographer asks when trying to understand a problem are: Where is it? Why is it there? How did it get there? How does it interact with other things? This course in physical geography will provide you with the tools to better understand the spatial distribution of natural phenomena. By the end of this course, you will be able to explain why San Francisco is always cold and foggy, why we have earthquakes and what causes seasons.
