Green house effect
Carbondioxide present in
the atmosphere absorbs
reflected from the surface
of the earth and heats up
This heating up of
carbondioxide in the air is
called green house effect.
Greenhouse gases in the atmosphere behave
much like the glass panes in a greenhouse.
But if the greenhouse
effect becomes stronger, it
could make the Earth
warmer than usual.
Importance of the greenhouse effect
Without the greenhouse
effect, the Earth would not be
warm enough for humans to
Because of Green house effect the average
temperature of the earth increases and this
is known as Global warming
Sunlight enters the Earth's atmosphere, passing
through the blanket of greenhouse gases.
Sunlight’s energy emains trapped in the
