Agents such as water, wind, ice, and gravity transport the sediment downstream, over dunes, or along geological faults. The process that alters their structure, whether through cracking, flaking, or complete disintegration, is known as weathering.

Conversely, tropical regions experience intense chemical weathering due to high temperatures and abundant rainfall, which accelerate chemical reactions and support dense vegetation whose roots pry rocks apart. 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.
Chemical Weathering Processes Unlike mechanical weathering, chemical weathering alters the molecular structure of the rock, transforming it into new minerals or soluble substances. 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.

Erosion: The Transport of Breakdown Weathering prepares the rock for removal, but erosion is the process that carries the broken material away. Hydrolysis and Carbonation Water is a universal solvent, but its power is amplified when it reacts with minerals.
