The process that alters their structure, whether through cracking, flaking, or complete disintegration, is known as weathering. Plant roots are powerful natural wedges; as a seed germinates in a rock crevice, the growing root exerts tremendous pressure, prying the rock apart.

Chemical Weathering Processes Unlike mechanical weathering, chemical weathering alters the molecular structure of the rock, transforming it into new minerals or soluble substances. This process weakens the rock's structure, causing it to crumble and turn reddish-brown, a familiar sight in weathered statues and building facades.
This action is particularly effective in mountainous regions and climates with seasonal temperature fluctuations. 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.
How Oxidation Breaks Down Iron Rocks
Oxidation and Rusting A specific form of chemical weathering is oxidation, which most people recognize as rusting. Erosion: The Transport of Breakdown Weathering prepares the rock for removal, but erosion is the process that carries the broken material away.
