1.  Solar system 

2. Green house gas effect 

3. Why venus Become hottest 

4. Impact on Earth 

5.  ice Age reation  green house gases 

6. Mars atmosphere 

7. Conclusion 

1. Solar system 

There are total eight planet in our solar system. Mercury is the closest planet to sun. Then Venus , earth , mars , and 4 others.

If Somebody ask you which is the 

hottest planet in our solar system You may say mercury because it is very close to the sun than other planet.

But hottest planet in our solar system is Venus.   You may think how Venus is hotter than mercury, but it's  possible only because of green house effect.

2.Green house gas effect 

 Green house effect means when planet receive heat from sun rays some heat  release in space and some heat absorb by gases called as green house gases. Green house gases. Green house gases are carbon dioxide, nitrous oxide, methane etc. 

3.Why venus Become hottest

Venus atmosphere  contain 98 %  carbon dioxide.

Carbon dioxide in Venus atmosphere absorb all heat coming from the sun rays,  which trap the all  heat coming from sun and increase the temperature of planet and Venus became hotest planet in solar system 

4. Impact on Earth 

Similarly increasing carbon dioxide in earth atmosphere giving signs of increasing temperature, for example glacier fall in uttarakhand. In present earth atmosphere contain 415 ppm carbon dioxide. we should have to decrease carbon dioxide emissions.

5. ice Age reation  green house gases 

 What happen when we make earth free from carbon dioxide?  About 500 million year ago when carbon dioxide in earth atmosphere reaches below 180 ppm and due to which glacial period start  and that end  2 million year ago. Glacial period means time during which large part of earth surface covered with ice.if we make earth atmosphere free from carbon dioxide then temperature of earth fall down . Earth need a 300 to 400 ppm carbon dioxide to keep earth surface warm. Carbon dioxide one of the major reason  from many other reasons evaluation of humans life. If carbon dioxide decrease below than 300 ppm   earth temperature start decreasing  and  Oceans  will start freezing. 

 6. Mars atmosphere 

Concentration of CO2 in atmosphere decide the temperature of any planet .  mars also contain 95 % carbon dioxide due to which mars temperature becomes 60 ⁰C.

along with distance from sun % of carbon dioxide in atmosphere decide the temperature of planet

7. Conclusion 

So we can say that roll of CO2  Is very important for temperature of planet  or   existing of life
