You mean, Plate Boundaries?

1. Convergent boundaries: where two plates are colliding.

Subduction zones occur when one or both of the tectonic plates are composed of oceanic crust.

2. Divergent boundaries – where two plates are moving apart.

The space created can also fill with new crustal material sourced from molten magma that forms below. Divergent boundaries can form within continents but will eventually open up and become ocean basins.

3. Transformed boundaries – where plates slide passed each other.

The relative motion of the plates is horizontal. They can occur underwater or on land, and crust is neither destroyed nor created.
