• A. Afforestation
• B. Control on Overgrazing
• C. Reclaiming mining land
• D. Dumping excavated land around mining areas

Answer 1

The correct option is D Dumping excavated land around mining areas

The process of dumping excavated land from mining areas to surrounding areas is called overburdening. The mining activities change the physical and chemical properties of the overburdened soil, thereby leading to land degradation. Such lands can be conserved by methods like afforestation, reclaiming the land to useful purposes, controlling overgrazing, and waste treatments.
