Plate Tectonics Guided Notes
1. Layers of the Earth and their composition
Inner Core
Outer Core
Mantle
Crust
2. Two Types of Crust:
_______________________ Crust
Properties:
_______________________ Crust
Properties:
3. The Earth’s crust is divided into 12 major plates which are moved in various directions.
This plate ___________ causes them to ___________, ___________, or ___________ against
each other.
Each type of interaction causes a characteristic set of Earth structures or “tectonic” features.
__________ refers to the __________ of the crust as a consequence of __________________.
4. The lithosphere is made up of the ___________ and the ______________________.
5. Plates are moved by underlying _________________________________ cells.
6. Three types of plate boundaries:
Boundary:
a)
b)
c)
Drawing:
What happens?
What forms?
7. Three types of convergent boundaries:
a) ___________________________________________________________ collisions
Form _______________________.
b) ___________________________________________________________ collisions
Called ______________________.
c) ___________________________________________________________ collisions
Form a ______________________.
Deep depressions formed in the ocean floor are called ______________________.
8. Volcanoes & The Ring of fire
Volcanism is mostly focused at _____________ _______________.
Volcanoes can be formed in 3 ways:
1) ____________________
2) ____________________
3) ____________________
Hotspot volcanoes form when ____________________________________________________
________________________________ of a tectonic plate.
An example is the ____________________________________
Because the mantle plume is stationary and the tectonic plate moves over the hot spot, the
volcanoes ______ _________________ from one end to the other.
9. Earthquakes
Like volcanoes, EQs occur near the _____________________________.
Movement along each of the 3 types of plate boundaries can form an EQ.
a) _____________________________ – The majority of EQs originate at a depth within a
________________________________________ and are caused by plates moving
against one another.
b) _____________________________________ – Occur in __________________________
and can be several hundred kilometers deep.
c) EQs can also occur in __________________________ and are caused by both
__________________________ and by the _______________________________ within
a volcano.
10. Summary
 The Earth is made up of 3 main layers (_________ , _____________ , ___________)
 On the surface of the Earth are __________________ ________________ that move
very slowly around the world
 ______________________ ________________ are made up of crust and upper mantle
 There are 2 types of plates (______________________ , ________________)
 There are 3 types of plate boundaries (_________________-__________________ ,
__________________-________________ , ________________-_______________)
 ___________________ & ______________________ are closely linked to the margins of
the tectonic plates.
