3. About Carbon Dioxide
• Carbon dioxide is the compounds of carbon is
is is present in the air
• It is formed when carbon and its compounds
are burnt in the air
• For example
C+O₂=CO₂
CH₄+2O₂=CO₂+2H₂O
.

4. • Carbon dioxide is colourless
• It does not suppot the combustion
• Denser than air
• Has a characteristic odourless
Properties of CO2

5. Carbon dioxide Cycle

6. • Photosynthesis is the process by
which carbon dioxide is utilised
by plant

7. • Raisng level of uses the vehicles and
deforestation are the activity that
increases the amount of carbon
dioxide in the air.

8. • Green house effect and global
warming are the consequences if
carbon dioxide amount increases.

9. • Do you know Green House
Effet And Global warming

10. • You have learnt that ultraviolet and infrared
rays also reach the earth's surface along with
sunrays. Infrared rays are thermal
radiations.Carbon dioxide present in the
atmosphere traps a part of the infrared
radiation that is reflected and radiated from
the earth.This is responsible for the present
temperature of the earth and its
atmosphere.This phenomenon know as Green
House Effect.When the amount of carbon
dioxide increases,more heat get trapped.As
the resut of green house effect,the average
temperature of the earth and its atmosphere
increasesThis is know as Global Warming.
