What boundary can create a volcano and how?
What is convergent and if the plates are the same density the plates move upward and can create a volcano or if one plate is denser than the other it creates subduction and magma starts to rise from the seduction underneath and creates a volcano.

Explain what happens when transform boundaries get stuck, what can happen when they get loose?
The transform boundaries build pressure when they get stuck and when they get loose they could cause earthquakes and tsunamis.
