The document discusses the greenhouse effect and how greenhouse gases like carbon dioxide and methane regulate the Earth's temperature. It explains that greenhouse gases in the atmosphere trap heat in a similar way that the glass walls of a greenhouse trap heat, keeping temperatures inside higher than outside temperatures. The greenhouse effect occurs when an increase in greenhouse gases leads to more heat being absorbed by the atmosphere and rising global temperatures.

3. GREENHOUSE EFFECT

4. THE GASES LIKE CARBONDIOXIDE &
METHANE AND WATER VAPOUR
FOUND INTHE ATMOSPHERE PLAY
AN IMPORTANT ROLE IN
REGULATING THE TEMPERATURE
THESE ARE KNOWN AS
GREENHOUSE GASES

5. THE GLASS HOUSE USED IN
COLD REGIONS TO GROW
PLAQNTS ARE KNOWN AS
GREEN HOUSE

6. THE TEMPERATURE IN THE GREEN
HOUSES IS USUALLY HIGHER THAN
THE OUT SIDE TEMPERATURE. THIS IS
BECAUSE THE GLASS ALLOWS THE
INCOMING SHORTWAVE RADIATION
OF THE SUN TO ENTER WITHOUT ANY
OBSTRUCTION & PREVENTS THE
ESCAPE OF THE OUT GOING LONG
WAVE RADIATION.

7. THE TEMPERATURE IN THE
GLASS HOUSES REMAININGS
HIGH.

8. THE ATMOSPHERE WITH THE
HELP OF GREENHOUSE GASES
RETAIN THE TEMPERATURE . IT IS
CALLED GREENHOUSE EFFECT

9. WHEN THE AMOUNT OF GREEN
HOUSE GASES INCREASES, THE
AMOUNT OF HEAT ABSORBED BY
THEM ALSO INCREASES WHICH IN
TURN RISES THE ATMOSPHERIC
TEMPERATURE.
