What are Tectonic Plates?
Large underground Plates that move around by Convection.
What are Plate Boundaries?
Boundaries where Tectonic Plates meet.
What is Subduction?
Where one Tectonic Plate descends under another.
What are Convergent Plate Boundaries?
Plate Boundaries where two Tectonic Plates run into each other.
What are Divergent Plate Boundaries?
Plate Boundaries where two Tectonic Plates travel away from each other.
What Natural Disasters can Plate Boundaries cause?
Volcanoes, Tsunamis, and Earthquakes are the main ones.
What can Hot Spots in the Ocean build?
Islands.
What are Transform Plate Boundaries?
Plate Boundaries where two Tectonic Plates run by each other. The San Andreas Fault in California is a Transform Plate Boundary.

What is Continental Drift?
The idea that the Continents have moved over time as a result of the Tectonic Plates. They used to be a combined mass called Pangaea.
