Transcript Inside the Earth

Essential Question: SPI 7.7.6
How are plate movements related to the processes of the Earth?
Activating Strategy:
Plot earthquakes and volcanoes on a world map. Have them compare the
activity of earthquakes and volcanoes to a plate tectonic map. OR Snickers
Lab “Plate Tectonics”
Teaching Strategies:
Create a flipbook with details explaining the three types of boundaries and
landforms associated with them.
Brainpop “Plate Tectonics”
Label a plate tectonic map.
Use white boards with flipbooks to identify the boundaries shown in the
PowerPoint.
Summarizing Strategy:
Complete the Plate Tectonic Graphic Organizer.

_________ Layer of molten iron and nickel that surrounds
the inner core.
_________ Thinnest, outermost layer of Earth; ranges
from 5 to 100 km thick.
_________ Name of the theorized super continent.
_________ Rigid layer consisting of the crust and
uppermost part of the mantle.
_________ Dense sphere of solid iron and nickel.
_________ Soft layer of the mantle on which pieces of
lithosphere slowly float.
_________, ________, __________, _____________
Four details that support Alfred Wegener’s Theory of
Continental Drift.

Epicenter
Point on Earth’s surface directly
above an earthquake’s focus
Seafloor
spreading
Hess’s theory that new seafloor
is formed when magma is
forced upward toward the
surface at a mid-ocean ridge
Rift
long crack, fissure, or trough
that forms between tectonic
plates moving apart at plate
boundaries
Location where one plate slips
under a less dense plate at a
convergent boundary
Subduction
zone

Convergent
boundary
Location where two plates come
together
Divergent
boundary
Location where two plates move
apart
Convection
current
Current in Earth’s mantle that
transfers heat in Earth’s interior
and is the driving force for plate
tectonics
Location where two plates move
opposite direction alongside each
other

Convergent Plate Boundaries
• plates move towards
each other
– Continent/continent
• High mnts form
– Continent/ocean
•
•
•
•
Subduction occurs
Trenches form
Volcanoes form
Strong earthquakes
Divergent Plate Boundary
• plates move away
from each other
• mid-ocean ridges
created through
a crack in
underwater crust
• new crust is
formed
Transform Plate Boundaries
• Crust neither created
nor destroyed
• Earthquakes created
from stress released
when the plates slide
along each other
• Example:
– San Andreas fault in
California

Tectonic Plates
• Earth’s crust is broken into pieces called plates
• These plates are part of the lithosphere and move on
top of the asthenosphere
• Boundaries are drawn by studying earthquakes and
volcanic eruptions.
