Which process can expose fossils that are concealed in rock?

Explanation:
Exposure of fossils happens when the rock surrounding them is worn away and removed. Erosion, driven by water, wind, ice, and gravity, gradually chews away the overlying rock and can reveal fossils that were hidden inside. Sedimentation burying remains would cover fossils deeper, not reveal them. Volcanism can disturb rock and sometimes expose materials, but it can also destroy fossils, so it’s not the typical process that reveals concealed fossils. Photosynthesis has no role in exposing fossils, since it’s a biological process rather than a geological one.
