Acid Rains & Global Warming


 

All living things need water to live. Rain is very important for life because, rain brings us the water we need. But in many places in the world even where you live, rain has become a threat.

 

What is Acid Rain?

The rain water polluted with poisonous and acidic gases is called Acid RainMost of the acid gases are blown into the sky, and when they mix with the clouds it can cause rain to become more acidic.

E.g. – Lemon juice, vinegar are all acidic. Rain is naturally acidic, but acid gases make it even more acidic, sometimes as acid as lemon!

 

Examples for acid gases

 

1) Nitrogen oxide

2) Sulphur dioxide

 

 

Causes of acid rain

 

1) Burning of fossil fuels like coal and oil.

2) Motor vehicles

3) Electricity generation

4) Industrialization

5) Urbanization

6) Use of engines and machines

7) Volcanic eruptions (Nature can also produce acid gases, such as volcanoes. When they erupt, the smoke that comes out of the crater is also full of acid gases.)

 

 

Air pollution all over the world

 

1) Air pollution can be carried all over the world.

2) When acid gases are released, they go high up in the sky.

3) Then they are pushed by strong winds towards other countries.

4) When rain is acidic, it affects what it falls on.

 

 

Bad effects of acid rains

 

On trees and plants

The acid takes away important minerals from the leaves and the soil.

 

On lakes and water life

Aquatic animals like fish and aquatic plants may end up dying, because they cannot survive in acidic lakes.

 

On our health

Water we drink from taps can be polluted by acid rain, which can damage the brain.

 

On buildings and statues

Acid rain can also damage buildings and statues because the acid eats into metal, stone and plastics.

E.g. –       The Statue of Liberty in the USA

               Taj – mahal in India

               Eiffel Tower in France

 

 

Global Warming

 

1) Humans, other animals and plants need heat or warm to live.

2) Sunlight warms land, water, and air.

3) In turn, the warmed-up land, water, and air give off heat, which rises up toward the sky (Warm air can rise).

4) Gases in the Earth’s atmosphere capture some of that heat and prevent it from escaping into space.

5) This heat trap keeps the ground, oceans and air at fairly safe, temperatures that thousands of plants and animals can bear it up.
