Which of the following best explains how soil can stop acid rain runoff from reaching streams and rivers?
Highly-acidic soils will neutralize the new type of acid before it can reach streams and rivers.
Organic matter in soil will use the acid for rapid decomposition before it reaches streams and rivers.
Low-acid soils will absorb and neutralize the acid water in its pores before it can reach streams and rivers.
Compacted soil formations like dense hills will make it impossible for acid rain to reach streams and rivers.
