continental
crust
oceanic crust
lighter, older, and thicker part
of the crust
much denser than continental
crust
lithosphere
crust and the rigid, immovable
part of the mantle
asthenosphere plastic-like, denser, semi-molten
layer of Earth
convection
 circular path of heating and
current
cooling
 moves the tectonic plates
Pangaea
 continents were joined
 similar rocks and fossils on
separate continents
 similar mountain ranges
divergent
boundary between two plates
boundary
that are moving apart
convergent two plates move together
boundary
mid-ocean
mountains chains at the bottom
ridge
of the oceans between continents
rift valley
magma rises between two
diverging continental plates
subduction
region where one plate slides
zone
under another plate
hot spot
P waves
S waves
 remains in one place as plate
above it moves
 creates chain of small
volcanoes
 compress and expand the
ground like an accordion
 first waves to arrive
 travel through both solids
and liquids
 vibrate from side to side as
well as up and down
 cannot move through liquids
