Acid rain / Nur Ezati Solikin

Acid rain is an environmental pollution categorized as air pollution. It is because the rains developed are being polluted on air by air pollutant before being deposited to earth as acid rain. Generally, acid rain can be classified as rain, snow, fog or dust polluted by the acid in the atmosphere. Acid rains were deposited back to earth in two forms; dry and wet. Dry deposition refers to acidic gases and particles, while wet deposition refers to acidic rain, snow or fog. There are two types of substances that commonly found in acid rain; sulfur dioxide (S02) and nitrogen oxide (NOx). Main source for sulfur dioxide emission is smokes from industrial activities while the main source for nitrogen oxide emission is smokes from vehicles. This project paper is discussing about acid rain in general view; such as what is acid rain, causes of acid rain, how acid rain affect our environment and how to prevent it from happening.
