Mr. Fleming

The trapping of heat from the sun by gases in the Earth’s

atmosphere.

The major gas contributing to this process is Carbon dioxide gas.

Greenhouse effect

When the sun shines on the

Earth some of its energy is

absorbed by the Earth’s surface,

some is reflected and some of the absorbed energy is reradiated by

the Earth.

Greenhouse effect

Since the Earth is cooler than the

sun the wavelength of the radiant Energy is

altered by the processes of

reradiating and reflecting of

energy.

Greenhouse effect

The new wavelength does not pass through

the atmosphere as easily and so it

becomes trapped by gases in the air.

Greenhouse effect

The gases associated with the trapping of

this heat are water vapor,

carbon dioxide, methane, nitrous oxide, and ozone.

What effect does adding more greenhouse gases to the atmosphere have on the amount of heat absorbed by atmosphere?

As the amount of greenhouse gases increases within the atmosphere, so does the amount of heat that is trapped.

Greenhouse effect

Since temperature differences create the convection currents that cause weather, changes to the warming of the atmosphere can cause

changes in weather patterns.

Name one major greenhouse gas that contributes to global warming.

Carbon Dioxide

What type of heat transfer does global climate change effect?

Convection Currents
