<u>Answer:</u>
Acid mine drainage which is also known as acid and ''metalliferous drainage'' or the acid rock drainage is the outflow of water from the metals of mine or coal mines. Some measures that can be taken to prevent acid mine drainage are Soil removal which involves movement of contaminated material to an area where it can be treated.
Direct treatment of the contaminated water through a water plant is another method. Contaminated land can be reclaimed by adding lime or another alkaline. Some more methods are Bacteria control, Diverting water from mine site to prevent it from running through AMD forming materials.
Answer:
FALSE
Explanation:
Aerosol are generally tiny particles suspended in the atmosphere. These can both be solid or liquid particles. These aerosols can either reflect or absorb sunlight depending on its properties, but most of the aerosols are "cool" type of aerosol. So, these aerosols generally decrease the overall temperature and work as an important counterbalance of the global warming caused by the greenhouse gases. These aerosols can also change the air circulation patterns by changing the temperatures by differential rate of sunlight absorption. Carbon aerosols like Soot are opposite to this nature. These absorbs the sunlight and make the atmosphere hotter.
At high concentrations these micrometer sized particles can be very much harmful for humans. Air pollutants produced from the burning of the fossil fuels causes approximately 5.5 million deaths worldwide.
So the answer will be false.
What is the passage that goes along with it?
They are formed by convectional current which is caused by sinking spreading of gasses liquid and molten materials.
