Acid Precipitation: precipitation that has been made more acidic than usual by the reaction of certain chemicals in the air with water vapour
Acid Precipitation: precipitation that has been made more acidic than usual by the reaction of certain chemicals in the air with water vapour
Effects of Acid Precipitation:1. acidification of aquatic ecosystems
Effects of Acid Precipitation:1. acidification of aquatic ecosystems
neutralizing: treating with a base to counteract the acid
e.g. liming a lake
Effects of Acid Precipitation:1. acidification of aquatic ecosystems2. damage to vegetation
Effects of Acid Precipitation:1. acidification of aquatic ecosystems2. damage to vegetation3. corrosion of buildings and vehicles
Effects of Acid Precipitation:1. acidification of aquatic ecosystems2. damage to vegetation3. corrosion of buildings and vehicles4. health problems(most related to sulfur dioxide & nitrogen
oxides breathed in

Water Pollution: Oil Spills: oil is toxic, slow to break down, and
difficult to clean up
Water Pollution: Oil Spills: oil is toxic, slow to break down, and
difficult to clean up (because its density is less than that of water, it forms large slicks that cover the ocean and beach)

Bioremediation: the use of micro-organisms (bacteria) to consume and break down environmental pollutants
Water Pollution: Plastics at Sea: plastics take thousands of years to
break down
