Mineral and Energy Resources — Important Questions

Unevenly distributed over space, Inverse relationship between quality and quantity, Exhaustible over time

Minerals have three main characteristics: they are unevenly distributed geographically, good quality minerals are found in smaller quantities compared to low quality ones, and all minerals are exhaustible as they take long geological time to form and cannot be replenished quickly.

North-Western Belt
