Question

how does acid rain affect soil over time?
it greatly improves the quality of the soil.
it decreases soil acidity.
it releases elements like aluminum and other metals.
it destroys the soil immediately upon touching it.

Explanation:

Acid rain has a negative impact on soil. It does not improve soil quality (so the first option is wrong). It increases soil acidity, not decreases (so the second option is wrong). Acid rain does not destroy soil immediately upon touching (so the fourth option is wrong). Acid rain can release elements like aluminum and other metals from the soil.

Answer:

It releases elements like aluminum and other metals.
