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.

•Trap heat from sun•Glass lets in light•Glass keeps heat from escaping•Causes greenhouse to heat up

Characteristics of Green House:

•Water vapor (H2O)•Carbon dioxide (CO2)•Nitrous oxide (N2O)•Methane (CH4)

Example of Heat Trapping Gases:

•Heat would escape back into space•Earth’s temperature would be 60ºF colder•Makes Earth suitable for life

Importance of heat trapping gases:

•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:

Process of Green House effect:

•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:

•Heating of the ground •Melting of ice and snow•Evaporation of water•Plant photosynthesis

The produced Energy used for:

•Deforestation and agriculture•Burning of fossil fuels, gasoline, oil •Burning of wood and coal•CFC’s•Population Growth

Causes of Green House Effect:

•Global Warming•Endangered Species•Climate Change

Dangerousness of greenhouse effect

•Reforestation•Personal Actions•Climate Policy

What can we do to reduce it:
