The document discusses the greenhouse effect, where greenhouse gases like carbon dioxide, methane, and chlorofluorocarbons in the atmosphere trap heat radiating from the Earth, causing the planet to warm. These gases prevent infrared radiation emitted from the Earth's surface from escaping into space, similarly to how a greenhouse retains heat. As a result of increased greenhouse gases from human activities such as burning fossil fuels and deforestation, the Earth's average temperature is rising in global warming. Effects of the greenhouse effect include melting glaciers and rising sea levels, and steps to reduce it include using alternative energy sources and replanting trees.

2. Energy from the sun reaches the earth
through radiation.
As the earth is warmed, heat in the form of
infrared radiation is radiated back into space.
However, much of this radiation is prevented
escaping into spaces by greenhouse gases.
THE GREENHOUSE EFFECT :D

3. Greenhouse gases include :
- Carbon Dioxide (CO2).
- Methane (CH4).
- Chlorofluorocarbons(CFCs).
- Nitrous Oxide (N2O).

4. As a result, the infrared radiation is radiated
back to the Earth’s surface, warming the earth
further.
The phenomenon is known as the greenhouse
effect. It’s similar to a greenhouse used in
farming in countries which experience
temperate climates.

5. The glass of a greenhouse allows light to
enter but retards the loss of heat. The heat is
used to keep the soil and air warm in the
green house.
The greenhouse effect caused by :
- human activities.
- burning of fossil fuels.
- deforestation.

6. The increasing amount of greenhouse gases
increases the greenhouse effect causing more
heat to be trapped in the atmosphere. The
Earth’s average temperature increases is
known as “global warming”.

7. Effects Of The Greenhouse Effect :D
Melting of polar ice and glaciers causing a rise
in sea level.
Intense rain in some regions.
Leads to greater climate changes like strong
winds & heavier rainfall.
Desert areas increase in size.

8. Steps To Reduce The Greenhouse
Effect :D
Reduce the burning fossil fuels.
Reduce the deforestation.
Practice replanting the trees.
Reduce or stop open burning.
Develop other sources of energy such as solar,
wind and geothermal energy.
