The truth or falsity of moral judgments, or their justification, is not absolute or universal, but is relative to the traditions, convictions, or practices of a group of persons. A subjective statement is one that refers to a subject. Anything else is objective.
Quick Answer. Subduction is a geological process that takes place at the boundaries between tectonic plates in which one plate is forced underneath another. Subduction occurs when the massive pressures of entire continental or oceanic tectonic plates collide, over the course of millennia, and one slowly is subsumed underneath the other.
In geology, subduction is the process that takes place at convergent boundaries by which one tectonic plate moves under another tectonic plate and sinks into the mantle as the plates converge. Regions where this process occurs are known as subduction zones. Subduction zones drag down subducted oceanic sediments, oceanic crust, and mantle lithosphere that interact with the hot asthenospheric mantle from the over-riding plate to produce calc-alkaline series melts, ore deposits, and continental crust.
