Answer:
1- Convergent plate boundary between two continental plates
2- Convergent plate boundary between a continental and an oceanic plate
3- Divergent plate boundary between two oceanic plates
4- Transform plate boundary
Explanation:
1) When two continental plate boundary shares a convergent plate boundary, then it results in the formation of the sandwich pattern where the two crusts are forced to rise up forming high mountain and mountain ranges. It is due to the compressive stress that acts on the plates. These mountains that forms are non-volcanic in nature. It results in the occurrence of deep-focus earthquakes. For example, the Himalayas.
2) When a continental and an oceanic plate shares a convergent boundary, then it leads to the formation of the subduction zone as the denser oceanic plate subducts below the less denser continental plate and above which there lies the trench. The plate that subducts melts at greater depth, thereby allows the magma to rise up towards the surface in the over-riding plate, giving rise to the formation of volcanoes and chain of volcanic and island arcs. These are habitable islands.
3) When two oceanic plate moves in the opposite direction, then it results in the formation of the mid-oceanic ridge where new materials are added to the crust and the size of the ocean basin eventually increases. It results in the formation of volcanic islands and also generates deep-focus earthquakes. For example, the mid-oceanic ridge.
4) When two plates slide past one another then it forms a transform type of plate boundary. The plates are conserved at this type of plate boundary. It generates shallow-focus earthquakes. For example, the San Andreas fault.
