The chemical composition of the limestone cobble remains the same when subjected to abrasion, as the mineral content does not change. However, the physical appearance and shape of the cobble will be altered due to the abrasion, resulting in smoother surfaces and potential changes in size and shape.

Abrasion loss refers to the loss of material from a surface due to repeated rubbing, scraping, or frictional wearing. It is often measured as a decrease in thickness or weight of the material over time. Abrasion resistance is an important property for materials used in applications where they are subjected to wear and tear.
Rock abrasion occurs when rocks are subjected to the mechanical wearing down by the impact of particles carried by wind, water, or ice. This process is also known as abrasion or erosion, and it results in the smoothing and shaping of rocks over time. It is common in environments with high levels of erosion, such as rivers, beaches, and glaciers.
Limestone erodes through a combination of chemical weathering and physical processes. Rainwater and carbon dioxide in the atmosphere react with the calcium carbonate in limestone, forming a weak acid that dissolves the rock over time. Additionally, physical processes like abrasion and freeze-thaw cycles can break down limestone into smaller particles.
Limestone can be worn away through a process called chemical weathering, where rainwater and acidic pollutants cause the rock to dissolve slowly over time. Physical weathering, such as freeze-thaw cycles and abrasion by wind and water, can also erode limestone by breaking it into smaller pieces. These processes combine to create features like caves, sinkholes, and cliffs in limestone landscapes.
Potholes in limestone regions are typically formed by the chemical weathering process known as carbonation. Rainwater combines with carbon dioxide in the atmosphere to form weak carbonic acid, which dissolves the limestone and creates cavities. Over time, the weakening limestone is further eroded by abrasion from sediment carried by water, eventually creating potholes.
abrasion resistance is the resistance in abrasion
The same type evident in all limestone caves, and in your country too!Chemical weathering - the limestone is dissolved by weakly acid water flowing through them. Some mechanical erosion by abrasion in high water, but this is a secondary mechanism.
They are subjected to wind erosion and weathering processes; moved from one place to another and reduced in size from abrasion.
Dental pellicle can be removed by abrasion involving extensive polishing which can only be performed by a dentist. Dental pellicle is the protein film which forms on the enamel surface.
