Flint Hills Geology (U.S. National Park Service)

The unique, stairstep landscape of the Flint Hills formed through a geological process called differential erosion. The limestone, with concentrations of flint, resists erosion more than the softer layers of shale in between. The tougher limestones and flint form prominent benches on the hillsides and cap the hilltops.

Adding Lime to Seawater | HowStuffWorks

During a process called calcination, calcium carbonate (limestone) is burned and decomposes into calcium oxide (pure lime). When the calcium oxide, a white powder, is mixed with water, it becomes calcium hydroxide (Ca (OH) 2 ). Calcium hydroxide is the lime that scientists talk about when they talk about adding lime to our oceans.

What is the reaction of limestone with water? - Frostburg State University

Limestone (CaCO 3) reacts with hydrogen ions in water. These are always present in water, since water undergoes autoprotolysis: H 2 O (l) = H + (aq) + OH - (aq) The more acidic the water is, the more limestone will react, and erode. The erosion of marble sculpture and inscriptions exposed to the elements is one of the consequences of acid rain.

Introduction to Adding Natural Decor to an Aquarium

Rocks such as limestone can contain CaCO3 which can cause the PH in the water to rise. CaCO3 is an alkali compound which acts as a neutralizer to the acid (vinegar), when an acid is poured on the rock the calcium carbonate neutralizes the acid therefore making it bubble. Without fully knowing what type of rock it is, boiling can be a risky process.
