This type of weathering occurs as a result of diurnal and seasonal temperature variations, which cause the alternate heating and cooling of rocks, now leading to the expansion and increase in their volume, now to its contraction and decrease. As a result of the regularly recurrent tensile and compressive stresses rocks undergo splitting and fracturing into fragments of different size. This weathering mechanism is particularly good with conglomerates.
