The Green House Effect

The greenhouse effectis a term that describeshow natural gases in

the earth's atmospherereduce the amount ofheat escaping from theearth into theatmosphere.

The more of thesegases there are, themore the Earth heatsup.


4/16

Greenhouse means?

Most greenhouses

look like a small

glass house.

Greenhouses are

used to grow plants,especially in the

winter.


5/16

Greenhouse Gases

Water vapor

Carbon dioxide

(CO2) Methane (CH4)

Nitrous oxide (N2O)

Carbon monoxide Ozone

Halocarbons

Smoke and Dust


6/16

Carbon Dioxide in the atmosphere

Photosynthesisbalance to keepthe amount of

atmosphericcarbon relativelystable.

Industrialization,has contributedadditionalcarbon dioxideto the

environment.


7/16

Solar energy isabsorbed by the Earthand the oceans.

Reradiates back on outinto the atmosphere,into stratosphere.

The burning of fossilfuel create a veil in theatmosphere

How does Greenhouse Effect occur?


8/16

Negative Effects

Droughts in mostof the agricultural

areas in the

world.


9/16

Negative Effects

The melting of thepolar ice caps

and subsequent

flooding of coastal

areas.


10/16

Hypotheses about the

Greenhouse Effect.

1. The Global Warming is taking place.

2. The Global Cooling is going to occur.

3. Neither Global Warming nor Cooling

will occur or has been occurring.


11/16

Effects of Global Warning on Life

Climate Change and

global Warming

Rise of sea Level Increase of disease

Environmental

Changing Increase of natural

disasters

How to reduce the Greenhouse

Effect BY THE GOVERNMENT:

Stabilization of the

population growth. Reduction of air pollution

from industries (internationalagreements)

Reduction of desertification

and protection of therainforest against theclearance (nationalprograms)

Finding alternative fuel

13/16


Effect BY PEOPLE:

Reduce the use of fossilfuel

Stop the clearance of

the forest

Follow therecommendations to

reduce the emission of

Greenhouse gases.


14/16


EffectBY US

Be well inform about the consequences

of Greenhouse Effect

Change your lifestyle habits to help

save the environment

Plant trees.

Eliminate the use of CFCs


15/16

Conclusion

Cutting down forest and burning fossil fuelscreate more CO2 in the air.

When there are more greenhouse gases,more heat is radiated towards Earthssurface, this produce Global warming.

Even global temperature changes of less

than 1 degree can cause problems, like sealevel rise and changes in rainfall.

Find solutions such as: reduce population,reduce air pollution, stop desertification.
