gravity collecting its debt from the mountain, all at once, no payment plan.

means A rockslide is the sudden, fast downhill movement of a mass of loose rock down a slope or cliff face.

from A plain English compound, bolting together "rock" and "slide." "Rock" descends from Old English and Old French stock (the French "roche," of debated and possibly pre-Latin origin), while "slide" comes from Old English "slīdan," to glide or slip — a word whose soft, slick sound has meant smooth downward motion for over a thousand years. Together they're a relatively modern geological pairing, the kind of self-explaining term that needs no further excuse: rocks, sliding.
