This web page provides a brief introduction to geothermal energy. It describes the different ways that heat energy from within the Earth is harnessed for human energy needs. It discusses the non-renewable nature of geothermal energy, the categories of geothermal resources, and the efficiency of geothermal resources.

This
online
publication
shows
how
chemists
and
geologists
used
analytical
chemistry
to
determine
the
age

Earth
and
to
show
that
an
extraterrestrial
body
collided
with
the
Earth
at
the
end
of
the
Cretaceous
period
(K-T
boundary).
There
are
also
chapters
on
the

This video documents an experiment conducted in Kane Cave, Wyoming, to see if microbes that inhabit the cave could actually be contributing to the cave-formation process. Adapted from a NOVA broadcast, the segment is four minutes and twelve seconds in length.

This
video
segment
shows
how
scientists
collaborate
to
collect
and
chemically
analyze
samples
of
molten
lava
as
part
of
their
quest
to
learn
more
about
how
volcanoes
work.
Working
at
Kilauea
volcano,
scientists
collect
samples
of
lava
before
it
has
a
chance
to
cool
so
they
can
study
the
chemical
properties
it
had
when
it
was
deep
within
Earth's
interior.
The
samples
are
sent
to

This
video
explores
the
role
of
biogeochemical
cycles
in
the
formation
of
caves.
It
discusses
a
radical
new
theory
that
identifies
sulfuric
acid
as
a
cave-forming
agent.
The
video,
adapted
from
a
NOVA
broadcast,
identifies
the
source
of
the
sulfuric
acid,
which,
unlike
carbonic
acid,
the
typical
cave-forming
agent,
does
not
readily
form
in
nature.
The
segment
is
5
minutes
and
forty
seconds
in
length.
