Continents
were
once
thought
to
be
static,
locked
tight
in
their
positions
in
Earth's
crust.
Similarities
between
distant
coastlines,
such
as
those
on
opposite
sides
of
the
Atlantic,
were
thought
to
be
the
work
of
a
scientist's
overactive
imagination,
or,
if
real,
the
result
of
erosion
on
a
massive
scale.

The
earths
crust
is
constantly
in
motion.
Sections
of
the
crust,
called
plates,
push
against
each
other
due
to
forces
from
the
molten
interior
of
the
earth.
The
areas
where
these
plates
collide
often
have
increased
volcanic
and
earthquake
activity.
These
images
show
the
locations
of
the
plates
and
their
boundaries
in
the
earths
crust.
Convergent
boundaries
are
areas
where
two
plates
are
pushing

This
site
provides
information
on
plate
boundaries,
which
are
found
at
the
edge
of
the
lithospheric
plates
and
are
of
three
types:
convergent,
divergent
and
conservative.
Wide
zones
of
deformation
are
usually
characteristic
of
plate
boundaries
because
of
the
interaction
between
two
plates.
The
three
boundaries
are
characterized
by
their
distinct
motions
which
are

This site gives an in-depth look at the theory of plate tectonics and how it works. The structure of the Earth is discussed, with brief rock type descriptions. The structure of the lithosphere, plate boundaries, interplate relationships, and types of plates are all covered in detail.

The distribution of earthquakes and volcanoes around the world confirmed the theory of plate tectonics first proposed by Wegener. These phenomena also help categorize plate boundaries into three different types: convergent, divergent, and transform.

In
this
lesson,
students
will
learn
to
distinguish
the
different
layers
of
the
Earth,
observe
the
effects
of
plate
movements,
and
explore
the
reasons
for
earthquakes
and
volcanoes.
They
will
label
and
measure
the
thicknesses
of
each
layer
of
the
Earth
(lithosphere,
asthenosphere,
etc.)
and
record
their
results,
construct

According
to
theory
of
plate
tectonics,
Earth
is
an
active
planet
--
its
surface
is
composed
of
many
individual
plates
that
move
and
interact,
constantly
changing
and
reshaping
Earth's
outer
layer.
Volcanoes
and
earthquakes
both
result
from
the
movement
of
tectonic
plates.
This
interactive
feature
shows
the
relationship
between
earthquakes
and
volcanoes
and
the
boundaries
of
tectonic
plates.
