A. Minerals: Minerals are naturally occurring solid substances formed through geological processes. They are finite resources extracted from the Earth's crust and are therefore considered exhaustible (3). B. Solar energy: Solar energy is energy derived from the sun. The sun is expected to continue providing energy for billions of years, making solar energy a renewable and inexhaustible resource (4). C. Biogas: Biogas is produced through the anaerobic digestion of organic matter. It is primarily composed of methane (CH₄) and carbon dioxide (CO₂) (2). D. Deforestation: Deforestation, the clearing of forests, has significant environmental impacts, including affecting local and regional climate patterns and contributing to changes in rainfall (1).
