Question

Which one of the following is not a part of chemical weathering?
A.Hydration
B.Exfoliation
C.Oxidation
D.Solution

Answer 1

Hint: Chemical Weathering is just another way of saying corrosion. Corrosion can be understood as the natural process because of which the base material is degraded to due to the formation of undesired products.

Complete Step-by-Step Answer:
Before we move forward with the solution of the given question, let us first understand some important basic concepts.
The products are formed as part of corrosion are formed as a result of the reaction of the base material with its surrounding. This corrosion usually takes place over a period of time. Let us now discuss the given options:
1.Hydration: Hydration can be understood as the reaction of the base material with water. Now, this water may either be in the liquid form, or it could be in the form of vapours. The moisture in the air also reacts with the base material to form water substituted products. Hydration causes extreme corrosion in highly reactive as well as mildly reactive metals.
2.Exfoliation: Exfoliation can be understood as a skin treatment process which is employed to clean dead skin cells. Exfoliation is one of the most popular methods of cleaning one’s skin because it clears the skin of any and all physical impurities from the pores of the skin.
3.Oxidation: Oxidation can be understood as the reaction of the base material with oxygen. Atmospheric oxygen is enough to corrode some materials to the point where the material has been completely degraded. The oxygen in the air reacts with the base material to form oxides of the parent element of the base material.
4.Solution: This is one of the less prevalent forms of corrosion as compared to oxidation and hydration. Solutions are formed when the base material gets reacted with either a certain gas in the air or with a liquid that is brought in contact with the base material.

Hence, Option B is the correct option

Note: Exfoliating is the process of removing dead skin cells from the surface of your skin using a chemical, granular substance, or exfoliation tool. Your skin naturally sheds dead skin cells to make room for new cells every 30 days or so. Sometimes, dead cells don't shed completely
