Answer 1

$\huge \tt \underline { \underline{ANSWER}}$

Before discussing answers of above questions you should first understand what green house effect actually is!

When the Sunlight reaches the Earth's atmosphere, some of it the rays reflect back into space and the rests are absorbed and re-radiated by greenhouse gases. The absorbed energy warms the atmosphere and the surface of the Earth.

Let's answer those questions :)

1.) The process of greenhouse effect takes place when gases in Earth's atmosphere trap the Sun's heat. Because of this process the temperature of earth becomes warmer than it would be without atmosphere. It is the process which makes Earth suitable place for living beings to live.

2.) Global warming is the overall increase in Earth's temperature due to green house effect.

3.) As we all know that today vehicle works on petrol (which is a fossil fuel) and we know that whenever fossil fuels are burnt they produce a lot of smoke. That's how pollution is created by vehicles. The pollution by vehicles include- carbon monoxide, hydrocarbons, nitrogen oxides, particles, volatile organic compounds and sulfur dioxide gases.

Vehicle which causes least pollution are those which work on CNG and electricit .Such as cars,E-Riksha, etc.

ANSWERS:

1)

• It is a natural process (Done by the earth itself).
• In the process the green house gases warm's the earth surface.
• The heat from the sun which reaches the earth's surface , some of the heat is reflected towards the space and the rest of it is absorbed by these green house gases.
• The heat is from the sun makes the atmosphere warm.

2)

• The slow and steady rise of the temperature of the earth due to the presence of green house gases is called global warming.
• The oxides of sulphur and nitrogen air will dissolve in the rainwater and acids.
• The rain is called acid rain.

$\sf Sulphur \: dioxide + Rain \: water \longrightarrow Sulphuric \: acid.$

$\sf Nitrogen \: dioxide + Rain \: water \longrightarrow Nitric \: acid$

3)

• Usually , vehicles run due to gases like Diesel and Petrol.
• When vehicles run due to these gases , They burn and smoke is produced.
• This smoke causes pollution.
• There are many kinds of vehicles which do not cause pollution = bicycle , electric bike , electric car etc.

Additional information:

• Burning a material in the presence of air ( oxygen ) is called combustion.
• Oxygen or air is needed for combustion to take place .
• The amount of heat produced on complete combustion of 1kg of fuel is called the caloric value of that fuel.
• Green house effect is a good thing.
• Green house gases warm's the earth surface and make it a comfort zone.
