A theory explaining the structure of the earth's crust and many associated phenomena as resulting from the interaction of rigid lithosphere plates that move slowly over the underlying mantle.

2.  The word, tectonic, refers to the deformation of the
crust as a consequence of plate interaction.
 Earth has seven lithosphere plates that account for
94% of earth surface. These are the
 North American
 South American
 Pacific
 African
 Eurasian
 Indo- American
 Antarctic
 This plate motion causes them to collide, pull apart, or
scrape against each other.

3.  Plates are made of
rigid lithosphere.
The lithosphere is made up of the crust and the upper
part of the mantle.

4.  Divergent
 Convergent
 Transform

5.  Convergent boundaries are boundaries where
two plate move towards each other.
 Convergent boundary is also known as
destructive margin since this is where
collisions between two plates occurs.

6.  Oceanic – Oceanic
 Oceanic – Continental
 Continental- Continental

7.  When two oceanic plates collide, one runs over the
other which causes it to sink into the mantle forming a
subduction zone.
 The subducting plate is bent downward to form a very
deep depression in the ocean floor called a trench.
 The worlds deepest parts of the ocean are found along
trenches.
Example:
The Mariana Trench is 11 km deep

9.  In Oceanic- Continental Convergence, on
oceanic crust collides with a continental crust,
forcing the denser oceanic crust to sink beneath
the continental crust. At the subduction zone,
partial melting occurs, leading to the formation
of volcanic arcs.

11.  In Continental-Continental Convergence, two
continental plates collide but instead of one
plate sinking beneath the other, folding occurs
and mountain ranges are formed.

13.  Mt. Everest, Himalayas
 The plates are still colliding and gaining
Elevation

14.  Is the opposite of convergent boundary: two
plates move away from each other, forming a
new land.
 It is also known as constructive margin.

16. Mid-Atlantic Ridge, Atlantic Ocean

18.  Is also known as Conservative plate margin
since two plates just slide past one another,
neither creating nor destroying land.
 It is usually at the transform fault boundary
where earthquake epicenters are found because
the rocks tend to break and not fold or sink.

past the North American Plate
at the San Andreas Fault.
