WHAT IS ACID RAIN?Acid rain is rain that is more acidic than normal.

Acid rain's spread and damage involves weather, chemistry, soil, and the life cycles of plants and animals on the land and from acid rain in the water.Sulfur dioxide and nitrogen oxides, the major sources of acid rain.

Deposition:-Deposition:- Wet deposition

refers to acidic rain, fog, and snow. As this acidic water flows over and through the ground, it affects a variety of plants and animals.

Dry Dry Deposition:-Deposition:-

Dry deposition refers to acidic gases and particles. About half of the acidity in the atmosphere falls back to earth through dry deposition

Burning coal, Oil and natural Burning coal, Oil and natural gas, in power stations makes gas, in power stations makes electricity, giving off sulphur electricity, giving off sulphur dioxide gas.dioxide gas.

Burning petrol and oil in Burning petrol and oil in vehicle engines gives off vehicle engines gives off nitrogen oxides as gases.nitrogen oxides as gases.

These gases mix with water These gases mix with water vapour and rainwater in the vapour and rainwater in the atmosphere producing weak atmosphere producing weak solutions of sulphuric and nitric solutions of sulphuric and nitric acids – which fall as acid rain.acids – which fall as acid rain.

Acid Rain increases the acidity of lakes & Acid Rain increases the acidity of lakes & rivers, which is directly effect the aquatic rivers, which is directly effect the aquatic ecosystem.ecosystem.

c). On Trees & Soilc). On Trees & Soil Acid Rain dissolves all the nutrients and the useful minerals

for the tree to grow.

Weakens the process of photosynthesis.

Acc. to modern researches, Acid Rain leaches potassium, calcium, magnesium, etc essential elements from the top of soil & When soil is contaminated, cereal (arable) production crops.

Acids activate aluminium from the soil which leaches into water and fish die. Drinking water is contaminated.

Acid rain was discovered in 1853. The term "acid rain" was coined in 1872 by Robert Angus Smith.
