Chemical weathering occurs at a higher rate as more CO2 is added to the atmosphere, lowering CO2 levels again. Moreover, the breaking down or dissolving of rocks and minerals on the Earth's surface is known as weathering. After a rock has been broken down, the bits of rock and minerals are carried away by erosion. Lastly, weathering is vital because it makes rocks porous and permeable, which is necessary for the occurrence of groundwater, and weathered soil is also fertile for agriculture. Furthermore, weathering generated economic mineral reserves such as bauxites. Weathering also produces inexpensive building stones.

Physical weathering can occur due to temperature, pressure, frost, root action, and burrowing animals. Soils form as a result of the weathering of materials on the Earth's surface, including mechanical and chemical weathering of rocks and minerals. The downward percolation of water aids in soil growth. Soil forms most quickly in temperate to tropical (not frigid) climates with moderate precipitation quantities (not dry, but not too wet).

There are three main factors that affect chemical weathering. Temperature, surface area, and accessible water all influence the rate. Chemical weathering involves three primary reactions: oxidation, hydrolysis, and carbonation.

Carbonation is a reaction with CO2 to generate a carbonate, whereas oxidation is a response with oxygen to form an oxide, hydrolysis is a reaction with water.

The rock given above is split in half due to Ice wedging. Ice wedging is a form of mechanical or physical weathering where the cracks in rocks or other surfaces are filled with water and when the temperature drops the water will freeze and expand causing the crack to grow and eventually breakdown the rock.

Weathering - is one of the geological processes, there are three types of weathering, physical, chemical, and biological, and it has a lot of different roles, such as; in soil formation, in the carbon cycle, in erosion, and many more. The role of weathering in soil formation is, it discusses the physical and chemical processes that transform soil, rocks, and minerals into other soil components. The means by which soil, rocks, and minerals are changed by physical and chemical processes into other soil components. Soil growth is incomplete without weathering. Also, since chemical weathering is negative feedback that stabilizes climate over long periods, it is the most important aspect of the carbon cycle.
