This boundary is described by two plates moving away from each other 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 each other ALONG THE EDGES horizontally. These boundaries will get stuck or lock against each other causing earthquakes when they slip and release.

• Convergent Boundary

• Divergent Boundary

• Transform Boundary

This boundary is described as moving toward each other. When the plates are both continental they will fold together and form mountains. When they are continental and oceanic plates, subduction occurs and volcanic mountains 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.
