ROCKS, ROCK CYCLE,
LAYERS OF THE EARTH, &
PLATE TECTONICS REVIEW
PLATE TECTONICS
• Study
of movement of
large masses of rocks
(plates)
PLATES
• Sections
of lithosphere
broken up that make outer
most layer Earth
EARTHQUAKE
• Occurs
when tectonic
plates slide past each
other
VOLCANO
• When
2 plates collide and
one sinks, melts, becomes
lava and comes up
through cracks
OCEAN BASIN
•2
plates move apart and
form more ocean floor
MOUNTAIN
•2
plates meet causing
them to move up
CONVECTION CURRENTS
• Heat
rising and cold
sinking resulting in
tectonic plate movement
WHERE ARE
ROCKS FOUND?
Igneous
Outside

Earth
Near Volcanoes
WHERE ARE
ROCKS FOUND?
Sedimentary
Outside
Earth on

LIST OF LAYERS
OUTER TO INNER:
 Continental
Crust
 Oceanic Crust
 Upper Mantle
 Middle Mantle
 Lower Mantle
 Outer Core
 Inner Core
Lithosphere
Asthenosphere
What happens in this layer?
• Convection Currents
WHAT DO YOU CALL
THE BROKEN PIECES
OF CRUST?
Plates
WHAT LAYER OF EARTH
DO WE FIND THE
TECTONIC PLATES?
Lithosphere
WHAT CAUSES THE
TECTONIC PLATES TO
MOVE?
Convection
Currents
WHAT TYPE OF GEOLOGICAL
EVENT IS PRODUCED IN THE
BELOW SCENARIOS:
Mountains or Volcanoes
Ocean Basins
Earthquakes
LIST THE MOTION OF THE
PLATES UNDERNEATH YOU IN
THE BELOW SCENARIOS:

If I were diving over the mid ocean ridge

If you were observing a volcano

If you felt the Earth shaking

If you were vacationing in the mountains
IGNEOUS ROCK
Forms
when hot
liquid/magma cools
and hardens
SEDIMENTARY ROCK
Forms
when rocks are
broken down into
smaller pieces and
harden
METAMORPHIC ROCK
Forms
when rock is
heated or squeezed
ROCK CYCLE
Continual
process by which
new rocks form from old
rocks
ROCK
Solid
mixture of
crystals of one or
more minerals
WEATHERING
Breaking
of rocks into
smaller pieces
EROSION
Wind,
Water, and Ice
break off and carry
grains of rock
DEPOSITION
Process
of water, ice, and
gravity dropping newly
formed sediments
COMPOSITION
Chemical
make up of
an object or combo of
minerals made of
