Wind-blown sand causes Mechanical Weathering of rocks by abrasion
Mechanical weathering includes abrading or crushing. Chemical weathering includes dissolution in water or acid rain. Oxidation and reduction reactions can also cause chemical weathering.
Weathering refers to the disintegration and decomposition of rocks. Pressure, temperature, acid rain, water, ice and wind all contribute to mechanical and chemical weathering.
This is chemical weathering. Carbonic acid (and often sulphuric acid from SO2) destroy CaCO3 (limestone) through chemical attack.Carbonic acid is formed by reaction of H2O and CO2 to create H2CO3.
Rapid chemical weathering can be caused by factors such as increased rainfall, higher temperatures, and the presence of acidic substances. These conditions can accelerate the breakdown of rocks and minerals, leading to faster weathering processes.
Mechanical weathering examples include frost wedging, where water seeps into cracks in rocks and freezes, expanding and breaking the rock. Chemical weathering examples include acid rain, where pollutants in the atmosphere react with water to form acidic precipitation that can erode rock surfaces over time.
Mechanical weathering breaks down the rock into smaller pieces, exposing more surface area. This allows the acid and chemicals to break down the pieces of rock faster.
to be honest in mechanical weathering plants grow their roots in the cracks of rocks. In chemical weathering plants grow their roots in the cracks of rocks, and the roots release acid that weathers away the rock.
