Question

Quizplus · Accepted Answer

Resources refer to the total amount of a material that exists in the Earth's crust, regardless of its accessibility or economic viability. Reserves, on the other hand, refer to the portion of the resource that has been identified, quantified, and is economically feasible to extract. While resources may be greater in quantity, their calculation involves more uncertainty and estimation than that of reserves.
