The distribution of natural resources worldwide is highly uneven, shaped by complex geological history, plate tectonics, climatic regimes, and evolutionary biology over millions of years. While fossil fuels like petroleum and coal concentrate in specific sedimentary basins, metallic ores align with ancient shield areas and convergent tectonic belts, and freshwater and arable land depend heavily on regional precipitation patterns. Mastering the global spatial distribution of energy, minerals, water, and biological resources is essential for economic geography, resource management, geopolitics, and competitive examinations.
