Sept. 18
• Density= Mass/Volume
• Out of the four layers of the earth. Which do
you think would be the most dense? Which
would be the least dense?
Today
• Interactive Notes
• Earth Layers Reading Due TOMORROW!!
What is the • Earth composed of rock
composition • ¾ of the earth’s surface
of the Earth? is covered by a thin layer
of water (some frozen)
• The Atmosphere (thin
layer of gas) surrounds
the entire planet
• Earth is made of 4
different layers:
– Inner core
– Outer core
– Mantle
– crust
What are •
characteristics •
of the Inner
Core?
•
Solid
Surrounded by a liquid
outer core
Unattached to the mantle
• Iron metal- mostly the
element Nickel
• The inner layer with the
rotational motion of the
Earth create a force fieldAKA a magnetic field
What are
characteristics
of the Outer
Core?
• Liquid
• Layer is dense
What are
characteristics
of the Mantle?
• Suspended by the
molten (liquid) outer
core
• Almost floats on top
• Thick
• Hot
What are
characteristics of
the Crust?
• Continental and
oceanic plates that
slowly move and
change positions
throughout geologic
time.
Sept.20
• Can heat move? If it can, how does it move?
When you heat a container of water, does the
water move or stay still?
IDENTIFY as Convection, Conduction,
Radiation

Sept. 26
• Finish your Pangea Activity
• Get out your Dynamic Earth Packet
– TONS OF PEOPLE DIDN’T TURN IN SO I NEED TO
PUT IN YOUR GRADES!!!
PROGRESS REPORTS AT THE END OF CLASS
Today
• Finish Pangea Activity
• Notes
• What you can play in your free times
What are
characteristics
of Plates?
• Plates move constantly
at rates of centimeters
per year as a result of
the movements in the
mantle.
• This results in major
geological events:
earthquakes, volcanic
eruptions, and mountain
building
What are the
three
movements of
plates?
–Convergent=
collide
–Divergent= divide
–Scrap alongside
each other
How do scientist
know all this? •
Seismologists have studied
seismic waves..
• Waves have characteristics:
frequency, wavelength,
amplitude, and speed.
• During an earthquake,
energy is released into Earth
as: Primary, Secondary, and
Surface waves.
