This page about acid rain for younger students describes both wet (rain, snow, fog) and dry (gas, dust) acid deposition and points out that both can be carried by the wind, sometimes for very long distances. It also explains the concept of acidity, how it is measured, and describes some of the harmful effects of acid deposition. Links to a glossary are embedded in the text.
