There are actually three major types of plate movement, not four, according to plate tectonics:

1. Convergent Boundaries: Plates collide with each other. This can result in:

* Subduction: One plate slides beneath the other. This leads to volcanic arcs, deep ocean trenches, and mountain ranges.

* Continental Collision: Two continental plates collide, creating massive mountain ranges.

2. Divergent Boundaries: Plates move apart from each other. This can result in:

* Seafloor Spreading: New oceanic crust is created as magma rises from the mantle.

* Continental Rifting: Continents can split apart, forming new oceans.

3. Transform Boundaries: Plates slide horizontally past each other. This results in:

* Earthquakes: The friction between the plates causes seismic activity.

These three types of plate movement are responsible for most of the geological features we see on Earth, including mountains, volcanoes, earthquakes, and ocean trenches.
