Overview of Plate Tectonics:
There are three different types of plate boundaries: convergent boundaries, transform boundaries, divergent boundaries. These are all displayed in the diagrams above from left to right. A convergent boundaries is when two plates are moving towards each other and collide, where as, divergent boundaries is when two plates move away from each other, and a transform boundary is when two plates slide/rub past each other. Because convergent boundaries and divergent boundaries are happening simultaneously, at different parts of the world, the Earth stays the same size. Convergent boundaries are where crust is destroyed and divergent boundaries are where crust is being made.
On Earth we have two types of lithosphere; oceanic lithosphere, and continental lithosphere. Oceanic lithosphere is the lithosphere at the bottom of the ocean and continental lithosphere is the lithosphere that we live on. When one piece of lithosphere is converging with another usually the more dense lithosphere goes underneath the less dense lithosphere. Oceanic lithosphere is denser than continental; therefore, it is the one that subducts. The age of the lithosphere plays a factor in which one subducts and the angle at which it subducts. Older lithosphere is known to be the one that subducts because it has been able to build up density with time, also the lithosphere's angle of subduction would be very steep because of it's density.

Overview of Philippine Plate Tectonics:
The tectonic setting of the Philippine Plate is complex. It is one of the smaller plates, yet it experiences all three types of boundaries. It is made up of a number of smaller pieces of lithosphere squeezed between two converging plate boundaries separated by subduction zones and transform boundaries.
