SOL REVIEW….PLATE TECTONICS
Read each fact carefully and then
be prepared to answer the
questions that follow
NO TALKING
HIGHLIGHT WHAT YOU DO NOT KNOW
HERE WE GO
Oceanic
Crust…thin,
young &
dense…sinks
Plate Tectonics
Continental
Crust… thick,
old & less
dense…floats
Volcano & Earthquake locations were used
to establish plate boundaries
3 Types of Plate Movement or Boundaries:
CONVERGENT
DIVERGENT
OLDEST Crust
YOUNGEST Crust
Sea Floor
being destroyed here
Sea Floor
being created here
TRANSFORM
Ex.
San Andreas Fault
Key words for each plate boundary include:
collision,→←,
pulling apart,←→,
sliding past each
crashing,
sea floor spreading
other,↑↓, strikesubduction zone
newest sea floor
slip, earthquakes
Features created at each boundary include:
Mountains,
Mid-ocean ridges, Hawaiian Islands were not
Volcanoes, Trenches,
Rift valleys & created by plate movement
Pangaea…one landmass
Volcanoes
but by HOT SPOTS
Plate Tectonics & Earthquakes 3 seismograph stations are
Earthquakes occur when there is
movement along a fault (crack)
needed to find the epicenter
Plate motion occurs as a result of convection
in Earth’s mantle. Plate movement is driven
by convection currents in the mantle.
Hot rises,
cold sinks
Epicenter
Earthquake & Volcanic activity is
associated with all plate boundaries
Earthquake Info:
Ring of Fire: surrounds the
P-Waves Arrive 1st & travel through solids and liquids
Pacific Ocean Plate…high area of
nd
S-Waves arrive 2 & travel through
earthquake/volcano activity
solids only…inner core of Earth is solid
Outer Core is Liquid
Epicenter (911) happens on
the surface of the earth
Focus happens deep inside
the earth…

Can you answer the following questions?
Movement of the crustal
plates shown in the diagram
is most likely caused by
The revolution of the Earth
The erosion of the Earth’s
crust
The crust at the midShifting of the Earth’s
ocean ridges is composed
magnetic poles
