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.
Answer:
Sediments are used to provide the proxies to understand the environmental changes as, the sediments are formed by the activity of the weathering from the wind, glacier and the water. The different weathering agent and other transportation agent are different types of the mark over the sediments that help in the study of the past environment.
Answer: I would say region
Explanation: The definition for region is an area having definable characteristics but not always fixed boundaries.

Answer:
Residential land use should be given priority in Ontario.
Explanation:
Ontario is the most populous province in Canada. Its approximately 15 million inhabitants make up 40% of the country's total population. Within the province is Toronto, the most important city in Canada, as well as Ottawa, the national capital, and other important cities such as Hamilton or London, among others.
Ontario is, in essence, Canada's economic engine. Its largest production is industrial, with different industrial and technological poles spread throughout the province. For example, in the city of London, the main industry is automotive production, while in Hamilton there are a large number of steel industries. Not minor are the energy, banking, financial and even agricultural industries in the province.
All this enormous production makes more and more labor want to move to the province, so it is necessary to expand the residential areas in order to receive all these workers and thus facilitate the expansion of Ontario's economic production.
