processes occuring at limestone areas

Sinkhole Wikipedia
A sinkhole, also known as a cenote, sink, sinkhole, swallet, swallow hole, or doline (the different terms for sinkholes are often used interchangeably), is a depression or hole in the ground caused by some form of collapse of the surface are caused by karst processes—for example, the chemical dissolution of carbonate rocks or suffosion processes.

In tropical areas with thick massive limestones, a remarkable and distinctive landscape of jagged hills and narrow gorges completely dominates the landscape. Movement of solution along fractures and joints etches the bedrock and leaves limestone blocks as isolated spires or pinnacles.

Weathering PGCE GEOGRAPHY CLASSROOM
Weathering and erosion are important physical processes in coastal areas. ... The process of freezethaw weathering occurs until the rock is weakened and shattered. ... joints, it reacts with the rock to form calcium bicarbonate. This is soluble and is carried away in solution, gradually weathering the limestone.

Deposition and Sedimentary Rock Formation
Limestone is composed of calcium carbonate (CaCo3), and can be the result of both organic and nonorganic processes. In marine environments, many plants and microscopic animals are able to extract calcium carbonate from the water to aid in the formation of hard outer shells.

Mechanisms of direct and indirect sulfation of limestone ...
In spraydry scrubbing, the desulfurization process with limestone takes place through a twostep process. First, the calcination of limestone occurs in a hightemperature furnace under low CO 2 partial pressures. The calcination process makes limestone decompose to calcium oxide (CaO), as expressed by the following equation.

How is limestone processed
Answer Slabs of limestone can be cut or faced for building material, sliced for countertops and tile, crushed to various dimensions for fill, roadbeds, and concrete aggregate, further crushed to a powder for agricultural lime, a soil conditioner, and heated to melting, then crushed to make portland cement.

How Does Climate Affect the Rate of Weathering? | Sciencing
Climate plays a definitive role in the breakdown of rocks into soils and sediment, a process known as weathering. Rocks found in equatorial climates and exposed to lots of rain, humidity and heat break down or weather faster than similar rocks do when located in areas of the world with dry and cold climates.
