Components

radical

山 shān

mountain

Top indexing radical 山 - pictograph of three peaks. Provides the 'mountain origin' part of the compound: rocks come from mountains. Same radical anchors 峰 (peak), 峡 (gorge), 岭 (ridge), 崖 (cliff). Stacked over 石 in classic top-bottom semantic compound layout.

semantic

石 shí

stone

Bottom 石 (stone) - pictograph of a stone falling from a cliff (the slanting top stroke is the cliff face). Compound ideograph: mountain + stone = boulder, rock outcrop. 岩 specifically denotes living bedrock as opposed to a loose 石. Same 石 in 砂 (sand), 矿 (ore), 砖 (brick).
