The spell check didn't find the errors because
the mis-spelled words are real words. They are just not the words
that the writer intended. If you look at the paragraph again, you
will see the mis-spelled words.
Green house effect is one of the phenomena
caused by industrial pollution. From the data taken by scientists,
our earth has been warming up since the Industrial Revolution. Why
does it happen? The factories' emissions have created smog on the
atmosphere. The earth's atmosphere becomes like a green house,
and the earth and everything inside of it have become like the plants
in the green house. The sunlight can pass trough the
ozone layer but the heat transferred by the sunlight can not escape
easily from the layer of smog and is deflected to earth's surface
again.
