Write Natural &manmade Reasons of Air pollution
and water pollution​

Answer 1

a) volcanic eruptions release gases and volcanic ash

b) bacteria,spores,cysts and pollens are all natural pollutant

2) man made sources of pollution

a) industrialisation

b) invention of automobiles

Answer 2

Answer:

NATURAL REASON:

1. VOLCANIC ERUPTION: SOLID, GASEOUS AND LIQUID MATERIALS EMERGE OUT THROUGH ERUPTION. EX. HYDROGEN SULPHIDE, SULPHUR DIOXIDE, CARBON DIOXIDE, AMMONIUM CHLORIDE, HYDROGEN, VAPOURS , DUST, ETC.
2. EARTHQUAKE: POISONOUS GASES AND WATER VAPOURS FROM INSIDE OF EARTH ARE RELEASED INTO AIR.
3. CYCLONES AND DUST STORMS: DUST , SOIL, GARBAGE, POLLENS, MICROBES ARE MIXED WITH AIR.
4. FOREST FIRES: FOREST FIRES RELEASE CARBON DIOXIDE, SULPHUR DIOXIDE, HYDROGEN SULPHIDE,SMOKE IN AIR.
5. MICROBES IN AIR: POLLENS OF PARTHENIUM, SPORES OF BACTERIA, FUNGI ARE MIXED WITH AIR.

MANMADE REASON:

1. FUEL: 1. BURNING OF FUEL LIKE COAL, TIMBER, LPG, KEROSENE, DIESEL, PETROL RELEASES CARBON DIOXIDE, CARBON MONOXIDE,NITROGEN OXIDE, SULPHUR DIOXIDE, LEAD COMPOUNDS, ETC. ARE RELEASED IN AIR
2. 2. BURNING OF SOLID WASTE, AGRICULTURAL WASTE, ETC. IN OPEN SPACE CAUSES AIR POLLUTION.
3. INDUSTRIALIZATION: SMOKE IS RELEASED IN LARGE QUANTITY FROM VARIOUS FACTORIES. SULPHUR POWDER, NITROGEN OXIDE, COTTEN SEED POWDER IN AIR.
4. ATOMIC ENERGY PLANTS AND BLASTS: USE OF ELEMENTS LIKE URANIUM, THORIUM, GRAPHITE, PLUTONIUM RELEASE RADIATIONS IN AIR AND THUS POLLUTION OCCURS.
