The predominant process of weathering in the desert region is physical weathering. Physical weathering is the breakdown of rocks into smaller pieces without changing their chemical composition. In the desert region, temperature changes and the movement of wind-blown sand and rock fragments can cause physical weathering. Over time, rocks in the desert are broken down into smaller pieces and eventually into sand, which can then be carried away by the wind. While chemical and biological weathering can also occur in the desert, physical weathering is the most common due to the unique environmental conditions in this region.
