In a dry climate, weathering is significantly less than in a humid climate primarily due to the lack of moisture, which is essential for chemical weathering processes. The absence of water limits the dissolution of minerals and slows down the biological activity that contributes to weathering. Additionally, physical weathering, such as freeze-thaw cycles, is less frequent in dry conditions, further reducing the rate of weathering. Consequently, rock surfaces tend to remain more intact in arid environments compared to their humid counterparts.
