Natural resources
Fuels like oil and coal, metals, and fresh groundwater are not spread evenly around the world. Where they're found today depends on geologic processes, both ones that happened long ago, like ancient sea life being buried and compressed, or volcanic activity concentrating metals underground, and ones still happening right now, like rivers depositing new sediment or groundwater slowly refilling underground reservoirs. Because humans keep removing these limited resources, often faster than they can naturally reform, their distribution keeps changing over time too.
