a young child becomes very sick and His does a series of tests to try to figure out what is causing his illness. his tests show that the child has generalized muscle weakness in many muscles all over his body, cellular damage to his nervous system, and heart irregularities. because the doctor knows that these organ groups (the brain, the heart, and the muscles)are especially sensitive to cellular energy levels, he believes he has found the answer.

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
