Geologic Resources: Mining and Extraction

The video tutorial explains geologic resources, which are naturally occurring substances mined from the Earth's crust. These resources include metallic minerals like aluminum and copper, nonmetallic resources such as salt and clay, and fossil fuels like coal and oil. Geologic resources are non-renewable, meaning they cannot be easily replaced once extracted. The video also covers extraction techniques like open pit and deep shaft mining, and the processing required to make these resources usable.
