Chemical weathering is the disintegration of a substance in the rock through a chemical reaction.
Carbonation occurs when water and a pollutant, such as sulphur dioxide creates a weak sulphuric acid. When it rains and the water comes into contact with limestone a chemical reaction happens. Calcium sulphate is produced as it takes the calcium carbonate from the limestone. It can then transfer the solution to another area until it evaporates. When it does so it leaves behind calcium information such as stalactites.
hydration occurs when minerals in a rock absorb water, causing it to expand. Mineral, such as anhydrite, expands and weakens it’s structure and leave the rock more exposed to erosion.
oxidation occurs some substances react to being exposed to water or air. Iron, when exposed, will turn from a silver color to a red or dark brown color known as iron oxide. It weakens the rock.
hydrolysis occurs when water bonds with a mineral in the rock. It is particularly strong at weathering feldspars in rock and can lead to the formation of Kaolin.
Urbanization refers to those areas of urban that can grow by increasing human population or migration of people from rural to urban areas & then it impacts our environment like deforestation, habitat loss and decreased of biodiversity.
Air pollution due to the high concentration of traffic and industries. Increased a greenhouse gas due to which it emissions a high levels of energy consumption and transportation. Urbanization affects our environment by improper or insufficient waste or smelly problem in urban areas.
Light pollution can be a ecological issues with different consequences. loss of green space and increase of heat island is also effected. It also affect our health due to increased risk of disease by overcrowding .
