The correct option is C.
Acid mine drainage refers to the outflow of acidic water from a mining site. This acidic water is usually formed as a result of the chemical oxidation of pyrite [iron sulphide, FeS2]which is often found together with valuable metals. 
Acid mine drainage occurs when water flow over or through sulfur bearing materials.

Choose ALL of the phases of matter listed<br> that are able to flow:<br> gas<br> liquid<br> solid
IrinaK [193]

Answer:

- gas

- liquid

Explanation:

     Part of the definition of gases and liquids is the ability to flow, so this answers your question.

     Why does this not apply to solids? The cells in a solid are closer together with less room for movement, so they do not "flow" like gasses or liquids. You can think of the device you are asking this question on versus the water in the ocean.

<u>Note</u>: Gas can still flow, but it does not flow the same as water. It depends on what you are being taught for if gas flows or not.

-> Liquid flows from high to low only, while gas can flow in all directions

Have a nice day!

     I hope this is what you are looking for, but if not - comment! I will edit and update my answer accordingly. (ノ^∇^)

     ★ Also please leave the rating you think I deserve (It helps other users as well as myself)
