Deposition of limestone.
We call the breakdown caused by acid rain, chemical erosion. The effects of acid rain (chemical erosion) include: damage to statues and buildings; weakening of the exposed metal on bridges and playground equipment; damage to wildlife, plants, forests and crops; and the contamination of drinking water supplies.

Hutton realized that an enormous period of time was needed to account for the repeated episodes of deposition, rock formation, uplift, and erosion that led to the formation of an unconformity, like the one at Siccar Point. ...
Limestone, rock made of the calcium carbonate mineral known as calcite, can form in a variety of depositional environments, from hot spring deposits in lakes to coral reefs in the tropical oceans. Most limestone originates in shallow waters of tropical oceans, and may carry fossils of plants and animals that lived in those marine environments.The deepening water will lead an overall shift in the facies to the left, such that the limestone will progressively be deposited on top of the existing shale rock and the shale facies will be deposited on top of the existing sandstone rock.Transgression occurs when the shoreline moves seaward, while regression occurs when the shoreline moves landward. Transgression and regression can be identified in sedimentary outcrops by looking for changes in the type and composition of the rocks. During a transgression, the shoreline moves seaward and deeper water sediments are deposited.

Sediment transport is the movement of organic and inorganic particles by water 10. In general, the greater the flow, the more sediment that will be conveyed. Water flow can be strong enough to suspend particles in the water column as they move downstream, or simply push them along the bottom of a waterway 11.The Newman Limestone records deposition on a shallow-marine carbonate shelf.

A type of limestone called coquina originates from beach sands made predominantly of shells that were then lithified. Coquina is composed of loosely-cemented shells and shell fragments.
An unconformity represents a period during which deposition did not occur or erosion removed rock that had been deposited, so there are no rocks that represent events of Earth’s history during that span of time at that place. ...
