Clays, derived from the weathering of feldspar and ferromagnesian minerals, form argillaceous sedimentary rocks like shales. This diurnal freeze and thaw cycle causes alternate expansion and contraction which introduce tension and stresses due to which rocks are disintegrated into smaller particles.
This process, often known as granular disintegration due to frost motion, is an exceedingly slow process and rocks are least affected by this process. The coarse-grained rocks are extra affected by shattering course of in those hot deserts that are characterised by high range of daily temperature. If the rocks are coarse-grained and are of…
