Surface area: A massive volume of unfractured rock is less susceptible to weathering than an equal mass of fractured rock. This is because the massive rock has less surface area on which atmospheric processes can act, whereas smaller fragments have a larger area upon which chemical and physical weathering can act.

CHEMICAL WEATHERING Essay - 1178 Words

Limestone gets pitted and porous due to chemical weathering. H2O + CO2 → H2CO3 → H+ + HCO3- CaCO3 + H2CO3 → Ca+2 + 2HCO3 2.

Chemical weathering does not break rocks into smaller fragments through wind, water and ice (that's physical weathering). Nor does it break rocks apart through the action of plants or animals (that's biological weathering).
