3. WHAT IS GREEN HOUSE?WHAT IS GREEN HOUSE?
• A greenhouse (also called
a glasshouse) is a structure
with walls and roof made
chiefly of transparent
material, such as glass, in
which plants requiring
regulated climatic
conditions are grown.

4. HOW GREEN HOUSE WORKS?HOW GREEN HOUSE WORKS?
 Greenhouses allow sunlight to enter but prevent heat from
escaping.
 The transparent covering of the greenhouse allows visible
light to enter without obstruction.
 It warms the inside of the greenhouse as energy is
absorbed by the plant, soil and other things inside the
building.

5. GREEN HOUSE EFFECTGREEN HOUSE EFFECT
 The process is called the
Green House Effect because
the exchange of incoming
and outgoing radiation that
warms the planet works in a
similar way to a
greenhouse.
 In short: it is the natural
process that warms the
Earth’s surface.

6. SOURCES OF GREEN HOUSE EFFECTSOURCES OF GREEN HOUSE EFFECT
1. Carbon dioxide (CO2)
2. Methane (CH4)
3. Water Vapor (H2O)
4. Nitrous oxide (N2O)
5. Clorofluorocarbons (CFC)

7. Carbon Dioxide (COCarbon Dioxide (CO22))
• Naturally produced when people and animals breathe.
• Plant take in and use CO2 to produce their own food.
• It is also returned to the air as a product of combustion and
decomposition.

8. Methane (CHMethane (CH44))
 CH4 is emitted by natural
sources such as wetlands,
as well as human activities
such as leakage from
natural gas systems and
the raising of livestock.

9. Water Vapor (HWater Vapor (H22O)O)
• Water vapor is the gaseous
phase of water. It is one
state of water within the
hydrosphere.
• Water vapor can be
produced from the
evaporation or boiling of
liquid water or from
sublimation of ice.

10. Nitrous oxide (NNitrous oxide (N22O)O)
• N2O is naturally present in the atmosphere as part of the
Nitrogen cycle.
• Sources: agriculture, fossil fuel combustion, waste water
management, industrial processes etc.

11. Clorofluorocarbons (CFC)Clorofluorocarbons (CFC)
• CFC’s are anthropogenic compounds that have been
released into the atmosphere since 1930s in various
applications.
• Sources: air conditioning, refrigerator, blowing agents in
foams, packing materials etc.

12. GLOBAL WARMINGGLOBAL WARMING
 A gradual increase in the overall temperature of the earth's
atmosphere generally attributed to the greenhouse effect
caused by increased levels of carbon dioxide, CFCs, and
other pollutants.

16. CONCLUSIONCONCLUSION
 The ‘Conclusion’ confirms that global warming is the major
challenge for our global society. There is very little doubt
that global warming will change our climate in the next
century. So what are the solutions to global warming? First,
there must be an international political solution. Second,
funding for developing cheap and clean energy production
must be increased, as all economic development is based
on increasing energy usage.
