Answer 2

Due the action of plate tectonics, compression, stress and shearing forces over long periods of time, rocks can be essentially warped and deformed, causing them to be compacted into a smaller volume of space. As a consequence, metamorphic rocks are always dense more than their original material, and also much less susceptible to erosional breakdown.
