One of the factors that determines the rate of weathering is climate. Regions that experience the most frost wedging tend to be
those where temperatures regularly hover near the freezing point of water (0°C). Why would regions that are significantly cooler or warmer than the freezing point experience less frost wedging?
A region’s climate plays a significant role in the rate of weathering. The climate of tropical rainforests plays havoc with rocks, rapidly breaking them into soils and sediment through repeated exposure to heat and copious amounts of rainfall. A haboob -- a violent desert dust storm -- sandblasts rocks into fine particles of sand, but not as fast as the rate of weathering that occurs in tropical climates.
