List the 5 LAYERS OF THE EARTH – in order.
Which LAYER includes the plates?
Why do the PLATES move? Primary cause – 2 words.
Which layer is the primary source of heat among our 5 layers?
Which layer is solid Fe (iron)?
Which layer is liquid Fe and Ni?
Which layer is the hottest layer?
Which layer is known as the “rock layer”? this layer includes our atmosphere…
We have CONVECTION CURRENTS moving melted rock and metal in the asthenosphere and mesosphere – true
or false?
Draw the arrows the represent a DIVERGENT BOUNDARY.
DIVERGENT BOUNDARIES cause gaps and trenches or uprising mountains?
CONVERGENT BOUNDARIES cause gaps and trenches or uprising mountains?
Draw the arrows that represent a CONVERGENT BOUNDARY.
Can you explain how a volcanic island is formed? Converging (colliding plates) Plates or transformation faults?
Every single time we have a PLATE SHIFT or MOVEMENT in a plate, we will have an
_______________________.
PLATE NAMES: look at the text on page 462 and make 100% certain you know 6 plate names:
a. North American Plate, Pacific Plate, South American Plate, Eurasian Plate, Austrailian-Indian Plate,
African (others: Nazca and Antarctica). How do you know? You know their shape first and name
associated…..you will have 3-5 questions on these SHAPES.
How elements are on our Periodic Table? (select an answer)
a. 100
b. 118
c. 148
Our Lithosphere (crust) has the same amount of every element – they are evenly distributed across the planet.
True or false
Which element did we talk about is found in virtually every rock, in the water and throughout the Lithosphere?
(oxygen, carbon, neon, iron)
Nearly all rocks are made of (carbon, silicon, iron, nickel)
Every living organism needs “the big 3” elements for life: (Sulfur, Hydrogen, Carbon, Phosphorus, Sodium,
Oxygen, and Zinc)
Everything dead or alive has some of this element inside. (Sulfur, Hydrogen, Carbon, Phosphorus, Sodium,
Oxygen, and Zinc)
In your ‘normal life’ you come in contact with a few elements everyday or most of the 118 elements?
Can you list the LAYERS IN ORDER without looking at your notes? DRAW / LABEL them on the back from the
center of the earth to the atmosphere.

Inner core, outer core, mesosphere, asthenosphere then lithosphere
Lithosphere
Heat and pressure cause the plates to move – pressure pushes the asthenosphere to move plates
Outer core because it’s made of liquid metal Fe and Ni
Solid? Must be inner core
Outer core is liquid
Outer core is hottest – hotter than the surface of the sun
Lithosphere
True, we have convection currents
Divergent
Divergent (di – divide) boundaries create trenches, gaps, valleys and cracks in the earth
Convergent (con – connect) boundaries cause mountains to rise slightly or create volcanic islands in some cases
Convergent
Volcanic islands are formed from plates colliding together and magma coming up to the water surface –
convergent boundaries.
Earthquake – there are earthquakes every single time we have plate shift or contact, most are small and don’t
create destruction thankfully.
No shortcuts – study your study guide or use the internet for images of the plates – know their shapes!!!
118 is the best answer
False – we don’t have every element in every state, much less every continent
Oxygen dominates our Lithosphere as the most common element we come in contact with.
Silicon or silica as some Periodic Tables describes this element.
C Carbon, O Oxygen and H Hydrogen
C Carbon
Considering that we have about 118 elements, we really come in contact with only few elements daily.

Mantle: composed of asthenosphere on top of the mesosphere (middle school vocab).
Crust: is our Lithosphere – plates, rock, stone (includes our atmosphere)
