Hi everyone ...
Mars has an atmosphere, but its gases are not the same as Earth �s.
Can anyone tell me where should the apostrophe be added in the underlined word? This sentence is taken from student �s book...shouldn �t it be written this way:
gas �s? I would appreciate it if someone enlightens me �cause i felt stupid when one of my students asked me for further explanation..thanks and Merry Christmess,,,, |

No apostrophe needed.
... its gases (= they) are...
(gas is used as a countable noun here, hence gases - there are several gases on Mars such as nitrogen, helium and argon)

There is no apostrophe in gases.
The possessive or genitive is the word its.
The possessive its has no apostrophe either - just like
his
hers
theirs - their
ours -our
mine
yours has no apostrophe either.

I think what your student wanted to know is the place of the apostrophe on the word Mars because it ends with an �s � and not on the word �gases � . It is obvious that the word gases does not need an apostrophe because of �its �.
Mars has an atmosphere, but its gases are not the same as Earth �s.
maybe the student had �Mars � instead of �its � in the sentence. If the sentence is as i guess it is the apostrophe would be on the letter �s �. It is also correct to put an �s
Mars has an atmosphere, but Mars � gases are not the same as Earth �s. |

The text - as far as I can see went like this:
Mars has an atmosphere, but its gases are not the same as Earth �s.
That sentence is correct.
There is no need to use the name Mars twice in one sentence - that �s why we use .pronouns.
