The main idea is that coal, oil, and minerals come from geological processes that take millions of years to form, so they are not replenished quickly. These are non-renewable resources because once they’re extracted and used, the natural formation processes cannot keep up with human consumption. Renewable resources, like sunlight, wind, and flowing water, can be replenished on a human timescale, which is why they’re not the right category here. The term inexhaustible would imply these resources never run out, which isn’t true for coal, oil, or mineral deposits. Recyclable describes whether a material can be reused after processing, but it doesn’t change the fact that the overall supply of these resources is finite; some non-renewable resources can be recycled, but their renewability status remains non-renewable.
