Question

A consequence of strip mining that produces sulfuric acid and can harm living things? A.) acid drainage B.)Fossil fuel use C.)Energy conservation D.)Pollution

Answer 1

A consequence of strip mining that produces sulfuric acid and can harm living things is "acid drainage".

Option: A

Step-by-step explanation:

The outflow of acidic water from a mining site is simply understood as acid mine drainage. It is the surface water contaminant in the mid-Atlantic region at present, get generated when water flows through sulfur-bearing materials which form net acidity situations. Here acid comes basically from oxidation of iron sulfide .

AMD is manufactured primarily from abandoned coal mines, and is currently being used in mining. It is a global issue, contributing to environmental degradation of watersheds and pollution of human water supplies by sulfuric acid and heavy metals like copper (Cu), lead (Pb) and arsenic (As).

Answer 2

Acid drainage results as a consequence of strip mining that produces sulfuric acid that can harm living things.

Step-by-step explanation:

Strip mining mainly done to mine coal destroys land surfaces and pollutes the biotic organisms and abiotic components like water, soil and air.

Acid mine drainage (AMD) from a mine refers to the acidic material outflow from a mining site. This acidic outflow mixes with surface ground water and will pollute it.

The net acidity of the AMD is mainly due to sulfur-containing compounds (mostly iron sulfide) which dissolves in the surface water and air. When rain occurs, it mixes with the sulfur dioxide present in the air and causes acid rain.

Effects of acid mine drainage

• The acidity of AMD is very high and reduces the pH of whichever water it mixes with. The water will be considered undrinkable and can leach and burn the skin surfaces when contact with it.
• These can kill the aquatic organisms when mixed in the water bodies.
• AMD when combined with other metals like arsenic, lead, cadmium etc present in the earth can produce more toxic substances.
• AMD can corrode metal structures.
