Acid mine drainage occurs when surface water infiltrates . A)

strip-mined coal beds and reacts with the mined coal

B)

spoil banks and reacts with minerals to create sulfuric acid

C)

land near coal mines and reacts with other water to form phosphoric acid

D)

groundwater and surface water supplies and reacts with the acids in these sources

E)

none of the above

E) none of the above

Explanation:

Mining can be defined as the process of extracting mineral resources from the Earth's surface such as seem, placer, ore-body, vein etc. Some examples of minerals that can be mined are gravel, gold, chalk, petroleum, limestone, coal, potash, rock salt etc.

The various techniques used for mining includes the following;

1. Sluicing.

2. Placer mining.

3. Hard rock mining.

4. Hydraulic mining.

Acid mine drainage can be defined as the quantity of acidic water that is being drained or flows out from a mining site.

Generally, acid mine drainage occurs when surface water infiltrates spoil banks where chemical reactions (oxidation) occur with pyrite such as iron sulphide.

I’m pretty sure it’s B

Explanation:

I’m taking the topic test right now I’ll get back with this

relative humidity, temperature and dew point -- are bound together in the mathematical relationship below. relative humidity changes when temperatures change. because warm air can hold more water vapor than cool air, relative humidity falls when the temperature rises if no moisture is added to the air. so i would say a
