Layers of rock.
Strata (singular: stratum) are the physical layers of sedimentary rock or soil laid down over time. They record depositional events (thickness, composition, fossils) — geologists read them to infer Earth history. (“Sections of geologic time” refers to time units, not the rock layers themselves.)
