Layers of the Earth
Notes
 ____________ – the thin outer layer of the Earth that is made up of
____________________.
 Types of Crust:
 _________________– the portion of Earth’s crust that
___________________________________________ .
 Very _______________ and less ____________
 _________________– the portion of Earth’s crust that
___________________________________________ .
 Very ________________ and very ___________
 ___________________– the rigid outer part of the Earth, consisting
of the _______________________________ and the
_____________________________________ .
 Made up of the ______________________________.
 _______________________– the putty-like layer of the
___________________ that the _______________ float on.
 Upper portion of _________________________.

____________________________ take place here.
Convection in the Mantle
A  ____________ of mantle material is ___________ than material
above it, so the _________________________________ .
B  ___________________ hits _____________________ and cannot
go up any further.
C  The __________________________ is causing denser material
_____________________________.
D  _________________ causes ___________________ to rise,
therefore ___________________________________ of material.
CauseEffectResult
 Cause
 __________________________ are caused by Earth’s internal
___________________ causing mantle to ______,
___________, and _________. As it gets closer to the crust it
______________, becoming ____________ and sinking
forming a current.
 Effect
 The convection currents act as a _____________________
moving the _______________________________ above.
 Result
 The results of plates moving are ___________________,
__________________, and building of _______________.
