What are the lithospheric plates and how do they interact?
The cool, rigid outer layer of Earth is highly fractured. In most places, huge chunks or pieces of this rigid outer layer, called plates, are in continuous motion. Plates can range from 50 km to 200km thick. Continental plates are thicker and less dense than oceanic plates that are formed at spreading ridges.
Viewers will learn to define a tectonic or lithospheric plate; differentiate between continental and oceanic plates; differentiate between the 3 types of plate boundaries; and learn about the generalized seismicity associated with boundaries.

Video lecture covers three basic types of tectonic plate boundaries.
In this exercise, students will learn about the various types of plate boundaries, investigate well-known examples of some of these boundaries, and then apply what they have learned to East Africa to determine the most likely cause of seismicity in this area of the world.
