What causes tectonic plates to move?

• Dense fluid in the asthenosphere sinks dragging the plates along as it sinks.

• As Earth rotates it causes the continents to shift and move.

• Volcanoes add new land to tectonic plates making them heavier and causing them to sink.

• Waves from the ocean push the plates along.
