Fill in the Blank, Plate Tectonics:
The Theory of Continental Drift was proposed by ______________ _______________
in 1912. The theory states that all the ________________ were once one __________________
named Pangaea and have since _____________ apart to their current locations. The evidence
that supports Continental Drift is: similar ____________ ___________ from different
continents, the landforms _____________ __________, and the _______________ of the current
continents fit together like a puzzle. The Continental Drift Theory has since changed into the
Theory of ___________ _____________. This theory states that the earth’s crust is broken into
large moving pieces called ________________ to which the continents are
___________________. Along with the evidence that was used to support Continental Drift,
new evidence such as _______ ____________ spreading, earthquakes and _________________,
and actual recorded _______________________ all help support Plate Tectonics.

The crust is broken into 16 plates: These plates shift and move in all directions. Where they
meet one another is called a plate ________________________.
There are three types:

A _________________ boundary is where the two plates move away from one another.
Here we find ______________ _______________ and ridges. New _____________ is

formed at these types of boundaries. An example of this type of boundary is the
_________ _______________ _____________.

A convergent boundary is where the two plates move _____________ one another.

If ________________ occurs, then one plate is forced underneath the other and
__________ trenches and coastal mountain ranges with _____________ are formed
along the boundary.

If _______________ occurs then both plates collide and push ___________ creating
______ _________________ with mild earthquakes. An example of this type of
convergent boundary is found in the ________________ ________________ of India.

The third type of boundary is called a ___________ _______________. At this boundary
the plates move ___________ one another in different directions. This movement creates
visible _____________ and lots of _____________. Prime example is the ________
___________ Fault in California.

During sea-floor spreading, new crust forms when molten material from the mantle will
rise up and fill in to form _______ ___________ ____________. The opposite edges of
the boundary then become _____________________.

4. In the rock cycle the processes of ________________ and __________________ produce
metamorphic rock. Sediments for sedimentary rock are produced by the processes of
_____________________ and _____________________ from the forces of the elements above
the earth’s surface. Igneous rocks form when molten material ____________ into magma and
______________________ as it cools.
5. List and describe the 3 steps of lithification:
