<u>Answer:</u>
Subduction of 'oceanic lithosphere' at the trenches can act like a 'bulldozer' to produce an accretionary wedge.
<u>Explanation:</u>
- The action of subduction subsequently results in a gradual layering up of material on 'both sides of the plate'.
- This process of layering up of the material from the plates is called as accretion.
- When a lighter plate undergoes subduction, it not only subducts but also lifts up the other plate to a certain extent.
- This action directly results in the formation of an 'accretionary wedge'.
The lithospheric plates move relative to each other. They are created at mid-oceanic ridges and destroyed at subduction zones. A mid-ocean ridge is an underwater mountain system formed by plate tectonics. It consists of various mountains linked in chains, typically having a valley known as a rift running along its spine. This type of oceanic mountain ridge is characteristic of what is known as an oceanic spreading center, which is responsible for seafloor spreading. The production of new seafloor results from mantle upwelling in response to plate spreading; this isentropic upwelling solid mantle material eventually exceeds the solidus and melts. The buoyant melt rises as magma at a linear weakness in the oceanic crust, and emerge as lava, creating new crust upon cooling. A mid-ocean ridge demarcates the boundary between two tectonic plates, and consequently is termed a divergent plate boundary.

Your question: Where does most of the star formation of a galaxy occur?
Your answer: In the bulge; the center on the galaxy is the place where most of the star formation occurs.
