bacteria
Along with saliva, bacterial secretions
form a sticky biofilm that accumulates as
plaque. Bacteria are embedded between
teeth and feed on the sugars that pass
through our mouths. The bacteria release
an acid that corrodes the enamel coating
of our teeth. Without regular brushing and
a proper oral hygiene routine, decay can
set in as the enamel is dissolved,
leading to gum disease.

Burning
blue
Kawah Ijen spews sapphire lava when it
erupts. The unusual nature of its
eruptions are the result of large quantities
of sulphur gas. When molten rock
emerges from deep below Earth’s crust at
high pressures and temperatures, it’s
joined by sulphur gas that also rushes to
the surface. When this sulphur gas,
heated to around 600 degrees Celsius,
reacts with atmospheric
oxygen, it burns blue.
