However, weathering can also be rapid, such as the damage to pavements or roads after a cold, frosty winter. Types of Weathering. Weathering is the initial step in soil creation. Weathering happens in four different manners: These include chemical weathering, physical weathering, biological weathering, and mechanical weathering.
Examples of chemical weathering: Minerals like calcium carbonate and calcium magnesium bicarbonate present in limestones are soluble in water containing carbonic acid (formed with the addition of carbon dioxide in water) and are carried away in the water as a solution.
A cluster of weathering processes namely solution, carbonation, hydration, oxidation, and reduction. These processes act on rocks to decompose, dissolve or moderate them to a fine clastic state through chemical reactions by oxygen, surface/ soil water, and other acids. Water and air along with heat must be present to speed up all chemical ...
Mechanical weathering is also known as physical weathering. In this type of weathering, a large rock is disintegrated into smaller pieces of rocks. When rocks disintegrate or break up without experiencing any change in their chemical composition, it is known as mechanical weathering.
The type of weathering caused by chemical reactions rather than by mechanical processes is known as chemical weathering. Five prominent examples of weathering are oxidation, carbonation, hydrolysis, hydration, and dehydration
It means weathering aids erosion, mass wasting and reduction of relief and modifications in landforms are a result of erosion. Weathering of rocks and deposits helps in the augmentation and concentrations of some valuable ores of manganese, aluminium, iron, and copper, etc. which have a great significance in the economy of the country.
When atmospheric pollutants like oxides of nitrogen and sulphur react with rainwater and come down with the rain, then this results in Acid Rain. Acid rain is made up of highly acidic water droplets due to air emissions.To study the causes, effects of Acid rain, along with a few examples and understand the prevention measures, FAQs.

Biological Weathering. Biological weathering only refers to weathering caused by plants, animals, fungi, and microorganisms such as bacteria. It is contributed to or removal of ions and minerals from the weathering environment and physical variations due to movement or development of organisms.
Physical weathering is also known as mechanical weathering. Chemical weathering takes place with the action of water, atmospheric gases, and biologically produced chemicals on rocks and soils. Water is the common agent in physical weathering and chemical weathering. Weathering is the main part of the rock cycle.
Rusting iron because of oxidation is the best example of chemical weathering. Oxidation occurs where there is ready access to the atmosphere and oxygenated waters. The minerals most commonly involved in this process are iron, manganese, sulphur etc.
