The primary driver of this type of degradation is the frequent freezing and thawing of water. Burrowing animals, such as moles and insects, disrupt the rock structure, exposing fresh surfaces to the elements and accelerating the overall decay of the material.
Wind Abrasion: How Wind Wears Down Rock Surfaces
Carbonation happens when carbon dioxide in the air or soil dissolves in rainwater, forming a weak carbonic acid that dissolves calcium carbonate found in limestone and marble, leading to the formation of caves and karst landscapes. While weathering breaks the rock down in place, erosion is responsible for sculpting the landscape, transporting the particles to new locations where they may eventually settle and form new sedimentary rocks, thus completing the cycle of rock transformation.
When temperatures drop below freezing, this water expands as it turns to ice, exerting immense pressure on the surrounding rock. This action is particularly effective in mountainous regions and climates with seasonal temperature fluctuations.

Chemical Weathering Processes Unlike mechanical weathering, chemical weathering alters the molecular structure of the rock, transforming it into new minerals or soluble substances. Erosion: The Transport of Breakdown Weathering prepares the rock for removal, but erosion is the process that carries the broken material away.
