•How does the
movement of Earth’s
plates affect our
planet’s surface?
Review Game:
Earth is Constantly
changing
What layer of earth has the greatest
amount of pressure?
•Inner Core
Which layer of Earth’s interior is
responsible for the magnetic field?
•Outer Core
The thickest layer of the earth is_____.
•Mantle
Which layer of the Earth is made up of
partly crust and mantle material?
•lithosphere
Where are the older rocks located
along the mid-ocean ridge?
•Farther away from the
center
The distance between Europe and
North America increases a few cm
every year. What causes this to
happen?
•Sea-floor spreading
What features of Earth are
produced by the movement of
lithospheric plates?
•Mountains, volcanoes,
and volcanic islands
What is the asthenosphere made of?
•Hot, soft rock in the
mantle
Where do earthquakes most likely
occur?
•At the border of
lithospheric plates
What makes up the lithosphere?
•The crust and upper
mantle
What causes the plates to move?
•Convection currents in
the asthenosphere
What type of plate boundary is shown
here?
•Diverging boundary
What type of plate boundary is shown
here?
• Convergent boundary
(continental plates)
What type of plate boundary is shown
here?
•Transform boundary
What type of plate boundary is shown
here?
•Subduction boundary
(continental/ oceanic)
What happens in a convection
current?
•Hot material rises, cools
becomes more dense
and then sinks
What three things increase as you
increase in depth of the Earth?
•Temperature, pressure,
and density
What is the thin layer of cool rock that
makes up the Earth’s surface?
•Crust
What type of rock makes up the
oceanic crust?
•basalt
What type of rock makes up the
continental crust?
•granite
What evidence did Wegner give for
continental drift?
•Land features, fossils,
and climate
What does Earth’s inner core and
outer core consist of?
•Outer Core- liquid metal,
•Inner Core- solid metal
Why did Wegner’s hypothesis get
rejected?
•Because he couldn’t
explain how the
continents moved.
The Moho is the boundary between
the …
•Earth’s crust and mantle
Where is a continental rift valley most
likely to form?
•Divergent plate
boundary
Where is an ocean trench most likely
to form?
•Convergent plate
boundary
Where is a mid-ocean ridge most likely
to form?
•Divergent plate
boundary
What will most likely happen when the
oceanic crust converges into the
continental crust?
•Subduction will cause
oceanic crust to melt.
Which boundary would be most likely
for an earthquake to occur in?
•Transform boundary
Which boundary would be most likely
for mountains to form in?
•Continental collision
boundary
What would most likely happen at the
mid-oceanic ridge once the plates have
separated?
•Rising magma will create
new crust
