  • EVR Chapter 11 Flashcards Quizlet

    Mining exposes unweathered rock surfaces that react with water and the atmosphere to generate acids. The acid is already present in trapped underground pockets and is released by mining equipment. Abandoned mining equipment leaks acids from batteries. Concentrated acids used to dissolve metals from the rock are picked up in rainwater.
