Plate Tectonics

Plate Tectonic Vocabulary

In the following days well define each of the following terms:

Lithospheric Plate
Plate Tectonics
Continental Drift
Seafloor Spreading
Diverging Boundaries
Sliding Boundaries
Converging Boundaries 

The Earth's crust is rigid and when it moves cracks and fissures are formed.  Much like when you crack a hard boiled egg shell.  The pieces of the crust fit together like a giant puzzle.  There are 8 major lithospheric plates and several smaller plates.  We are going to put the pieces of the puzzle together and label the major plates.  The directions these plates are moving create many of the landscape feature that we see all around us.
