Question

do sedimentary rocks go through granular disintergration?

Answer 1

The major processes of physical weathering and rock disintegration in Antarctica are glacial action; the action of water in various forms, as liquid, ice and vapor; salt weathering; insolation and wind action. The regolith is formed through the combination of these processes. The effectiveness and the extent of chemical weathering declines as the distance from tropical regions increases, consequently physical weathering processes that induce rock decay gradually assume a much more significant role with increasing latitude, due to lower temperatures and a lesser availability of moisture. Due to the relative insignificance of chemical weathering, physical processes are most important for regolith formation and soil development in Antarctica, but the very arid environment restricts the effectiveness of processes such as freeze and thaw. while the intense cold diminishes the influence of glacial erosion. The combination of extreme cold and aridity acting over long periods of time has produced many unusual features which need to be taken into account when considering the origin of the regolith and subsequent soil formation. Differences in mode of ablation. windiness, available moisture, salt deposits, aspect, and rock type may all exert an influence on regolith formation. Within the regolith itself, physical processes including patterned-ground formation and granular disintegration also influence the expression of soil morphology.
