    Nov 09, 2016· Tectonic plates, the massive slabs of Earth's lithosphere that help define our continents and ocean, are constantly on the move. Plate tectonics is driven by a variety of forces: dynamic movement in the mantle, dense oceanic crust interacting with the ductile asthenosphere, even the rotation of the planet.

    How plates move. The edges, or boundaries, of tectonic plates meet up in different ways. There are three main types of boundaries: transform, convergent, and divergent. At transform boundaries, plates move past each other. This is one of the most common causes of earthquakes. At convergent boundaries, plates move toward each other.

    Tectonic plate movements. Convergent: occurs when plates collide producing ground elevations.They can also happen when an oceanic plate sinks below the continental plate by means of subduction, when the upper plate rises above the lower one. When one plate sinks on top of the other, sea pits form. Divergent: The plates separate when magma emerges from the depths of the earth's mantle.
