Identify the functions below as belonging to one of these radio transmission devices: oscillator, transmitting antenna, microphone, or modulator. A. Sends out radio waves having the same frequency as the current supplied by the oscillator. B. Enables the waves produced by the antenna to “carry” the pattern of the sound waves picked up by the microphone. C. Converts a direct current into a high-frequency alternating current. D. Picks up sound waves and converts them into suitable electric current with the same pattern as the sound waves.

Subduction zones form when an oceanic plate collides with another oceanic plate or continental plate. the continental crust is lighter and less dense than oceanic crust. continental crust's density is approximately 2.7 grams per cubic centimeter. oceanic crust is thinner and the average density is about 3.3 cubic centimeters. when the two crustal plates converge the oceanic plate always bends and subducts beneath a continental plate. once the oceanic crust subjects, the rocks are subjected to changes in heat and pressure. because of this, we would expect to find rocks in the area of a subduction. a) clastic b) igneous c) metamorphic d) sedimentary
