This boundary is described by two plates moving away from eachother along the edges and separating. The resulting gap allows magma to rise and create new crust, forming new lithosphere. 

• Convergent Boundary 
• Divergent Boundary  
• Transform Boundary

This boundary is described as two plates moving past eachother ALONG THE EDGES horizontally.  These boundaries will get stuck or lock against eachother causing earthquakes when they slip and release. 

• Convergent Boundary
• Divergent Boundary
• Transform Boundary

This boundary is described as moving toward one another  When the plates are both continental plates the will crumple up and form a mountains. When they are continental and oceanic plates, subduction occurs  and earthquakes and volcanoes form.

The movement of the tectonic plates is caused by

• the rotation of the Earth.

• convection currents in the Asthenosphere

• the gravity of the iron-nickel core.

• the Moho discontinuity.
