The planet's bones, sitting patiently under everything you've ever built, lost, or buried.
means The solid layer of unweathered rock lying beneath soil and looser sediment — or, figuratively, the firm foundation on which something rests.
from A plain English compound, simply 'bed' plus 'rock' — an American coinage from the early 19th century, born in the practical language of mining and geology. 'Bed' here carries its old sense of a layer or stratum (as in 'riverbed'), the same word as the thing you sleep on, both descending from Old English 'bedd,' a place laid down. So bedrock is literally the rock-layer at the bottom, the one everything else is bedded upon — and from the geologists' pits it rose into everyday speech as a metaphor for any unshakeable base.
