8. What is Global
Warming ?
A slow but sure escalation in
the overall temperature of the
Earth's atmosphere generally
attributed to the g r e e n h o u s e
effect caused by increased
levels of c ar bo n d io x i d e ,
CF C s, and other pollutants is
called G l o b a l W a r m i n g .

11. When greenhouse gases
like carbon dioxide, methane,
chlorofluorocarbon(CFC’s) etc.
trap the outgoing solar
radiations of the sun
reflected by the surface of
the earth and do not allow the
heat to escape then this is
known as greenhouse effect
which causes GLOBAL
