published
by
the
United
States
Geological
Survey
(USGS).
It
is
intended
to
provide
a
brief
introduction
to
the
concept
of
plate
tectonics,
highlighting
some
of
the
people
and
discoveries
that
advanced
the
development
of
the
theory.
It
is
the
companion
volume
to

in
the
way
these
processes
proceed
in
wet
and
arid
environments,
the
role
of
flash
floods
and
debris
flows
in
moving
large

This
article
discusses
the
idea
of
'hot
spot'
volcanoes,
those
not
associated
with
plate
tectonic
boundaries,
but
rather
with
relatively
stationary
sources
of
heat
energy
(thermal
plumes)
in
the
mantle.
Topics
include
the
development
of
the
theory
by
Canadian
geophysicist
J.
Tuzo
Wilson;
the
mechanics
of
volcanism
over
a
hot

as
seen
in
