Earths Tectonic Plates are divided into seven large and 12 smaller plates.
The Earth's crust is between 10 and 100km thick.
There are two types of crust:
Oceanic Crust: between 5 and 10km thick, the crust is continually being renewed and destroyed.
Continental Crust: between 25 and 100km thick, it does not sink and it is not destroyed.
Three different plate movements:
Plates move towards each other... CONVERGENT OR DESTRUCTIVE (boundaries)
Plates move apart... DIVERGENT OR CONSRUCTIVE (boundaries)
Plates slide past each other... CONSERVATIVE OR TRANSFORM (boundaries)
Plates meet at plate…
