Subduction zones. Subduction zones form when a continental plate is colliding with an oceanic plate. Subduction zones also form when two oceanic plates collide. The continental crust is lighter because of the quartz and feldspar minerals in granite.Iron and magnesium are much heavier minerals found in ocean floor basalt. When the two plates meet the oceanic crustal plate always subducts beneath the continental plate.The subducting oceanic plate bends and plunges beneath the lighter continental plate until it melts. When two oceanic plates meet and form a subduction zone the heavier and denser of two oceanic plates subducts.ubduction zones also form when two oceanic plates collide.

A HealthCorps answered. A few things happen to enable our ears to hear: 1  Sound waves enter your ear canal and cause your eardrum to vibrate.  Vibrations cause the fluid in the cochlea to move, stimulating the receptor cells.
Report Abuse. All moving things produce sound waves that travel through the air at high speeds. When they get to your ear they bounce against the ear drum and it sends signals to your brain that let you iterpret them.That is how when there is a loud noise or explosion it can vibrate the ear drum to much and can actually rupture it.he sound waves vibrate the eardrum, which triggers the ossicles to move the sound into the inner ear (cochlea). Then the hairs within the inner ear vibrate. This movement sends signals to the brain, which untimately interprets the sound.
