Introduction Of Green House:
The greenhouse effect is a natural process that warms the
Earth surface. When the Sun energy reaches the Earth
atmosphere, some of it is reflected back to space and the rest
is absorbed and re-dispersed by greenhouse gases. The
absorbed energy warms the atmosphere and the surface of the
Earth.

6. •Trap heat from sun
•Glass lets in light
•Glass keeps heat from
escaping
•Causes greenhouse to heat
up
Characteristics of Green House:

7. •Water vapor (H2O)
•Carbon dioxide (CO2)
•Nitrous oxide (N2O)
•Methane (CH4)
Example of Heat Trapping Gases:

8. •Heat would escape back into space
•Earth’s temperature would be 60ºF colder
•Makes Earth suitable for life
Importance of heat trapping gases:

9. •Suppose a Car, parked under Light
•Glass lets in light
•Glass keeps heat from escaping
•Causes the car to heat up
Example of Green House Effect:

10. Process of Green House effect:

11. •Sun’s energy passes through atmosphere
•26% is reflected or scattered
•19% absorbed by clouds, gases, and particles
•4% reflected to space by surface
•51% reaches the surface
Process of Green House effect:

12. •Heating of the ground
•Melting of ice and snow
•Evaporation of water
•Plant photosynthesis
The produced Energy used for:

13. •Deforestation and agriculture
•Burning of fossil fuels, gasoline, oil
•Burning of wood and coal
•CFC’s
•Population Growth
Causes of Green House Effect:

14. •Global Warming
•Endangered Species
•Climate Change
Dangerousness of greenhouse effect

15. •Reforestation
•Personal Actions
•Climate Policy
What can we do to reduce it:
