Question

Identify the correct statements about acid rain.
I. Acid rain is caused by nitric acid and sulfuric acid.
II. Acid rain can damage plants directly.
III. Acid rain can cause magnesium and calcium to be leached from the soil.

• A. I only
• B. II only
• C. III only
• D. Both II and III
• E. All of the above

Answer 1

The correct option is E All of the above

Acid Rain is any form of precipitation with acidic components, such as sulfuric or nitric acid that fall to the ground from the atmosphere in wet or dry forms.

It can have harmful effects on plants, aquatic animals and infrastructure. It weaken the trees by damaging their leaves, limiting the nutrients available to them, or poisoning them with toxic substances slowly released from the soil.

Soil chemistry can be dramatically changed when base cations, such as calcium and magnesium, are leached by acid rain thereby affecting sensitive species. Hence, the correct answer is option D.
