The air near the centre of an active
volcano is so sulphurous .......... .
during eruptions poisonous gases fill
the air making it almost impossible to
breathe
even though scientists wore special
masks which filtered the air to enable
them to carry out their studies
whether or not scientists can study
them depends on the amount of
sulphur in the air
that scientists need to wear special
breathing equipment when
studying volcanic activity
yet these sulphurous gases give off a
strong smell similar to that of rotten
eggs
