Weathering of Limestone
Due to the nature of limestone to slowly dissolve when in the presence of a light acid as well as allow water to pass through the matrix of the limestone, many cave formations are as a result of large limestone deposits. Another geologic landform in which limestone plays a key factor in its generation is asinkhole. Areas in

The processes of dissolution, where surface rock that are soluble to weak acids, are dissolved, and suffusion, where cavities form below the land surface, are responsible for virtually all sinkholes in Florida. DISSOLUTION SINKHOLES. Dissolution of the limestone or dolomite is most intensive where the water first contacts the rock surface.

Limestone areas throughout the Indonesian archipelago originate from jurassic, cretaceous, tertiary and quarternary times. Forests over limestone are usually a mosaic of rich and poor growth due to free-draining, steep slopes, water stress, high concentrations of calcium and magnesium, richer soils between jagged peaks and pinnacles.

The greater the weathering of limestone, the more CO2 is removed from the atmosphere. As limestone dissolves faster than silicate rocks, the chemical weathering of limestone accounts for more of the total chemical erosion of the land surface than any other rocks, even though much larger areas of the Earth consist of silicate rocks.

It occurs both in mountains and hot deserts in places where the temperature fluctuates around 0 degrees Celcius. It occurs in rocks which have cracks and joints (lines of weakness).

Calcination of CaCO3 is a highly endothermic reaction, requiring around 755 Mcal of heat input to produce a ton of lime (CaO). The reaction only begins when the temperature is above the dissociation temperature of the carbonates in the limestone. This typically is between 780 deg C and 1340 deg C.

Limestone is an alkaline agent with the ability to neutralize, or partially neutralize strong acids. The neutralization process occurs when strong acids, in intimate contact with limestone chips, react with Calcium Carbonate (CaCO 3, the primary constituent of limestone) to form water, carbon dioxide, and calcium salts. What is soil limestone?
