It is an involuntary action.

Explanation:

When the boy got electrocuted/shocked by the cable the feeling immediately went to his spinal cord and the nerves in the spinal cord contracted his muscles in his arm causing it to pull away from the cable. I don't know if this made sense to you but I hope it helped.

igneous rocks also form where plates converge. the subducting plate melts as it sinks into the crust of the earth, and the melt rises into the overriding plate forming volcanoes. metamorphic rocks are formed mainly in the lithosphere, wherever there is high pressure and high temperature. -woods
