Answer:
1 - Transform plate boundaries
2 - Convergent : Subduction
3 - Convergent : Collision
4 - Divergent
Explanation:
1 - The main reason why there are earthquakes at transform plate boundaries is, sometimes as they slide past each other they may stick for long periods of time and when they eventually release a shock wave is felt.
2 - Subduction occurs when the heavier tectonic plate, in this case the oceanic plate slides under the continental plate
3 - Folding occurs when two continental plates crash into one another, no subduction occurs as they are the same mass instead the fold upwards to form mountains this is how the Himalayan mountain range was formed
4 - At divergent plate boundaries magma rises up this usually occurs underwater to form islands
