Many pathways and agents are involved in weathering, but most can be grouped into two main processes: mechanical and chemical weathering. Biological weathering is caused by plants and animals and its action speeds up mechanical and or chemical weathering. Chemical weathering is what happens when rocks are broken down and chemically altered. That came later, with the discovery of how genes encode different biological or behavioral traits, and how genes are passed down from parents to offspring. This type of weathering happens over a period of time. Often the types of plants growing in a certain area depend on how the rock and soil have been weathered. The recycling of elements by plants and plant-induced biological activity cause the rates and products of weathering to be markedly different from what would result in abiotic processes. The process may involve freezing of a capillary film of adsorbed water and capillary movement through the rock toward the freezing front.
