What is chemical weathering? Name different process involved in chemical weathering? How is weathering influenced by climate?(I want very long ans for about 10-12 marks.If u give me very long ans I will mark u brainliest and I will follow u. If you don't give ans, then I want ans from 'ItsSofia' because she give me a very long ans and have started following her please give me a very long ans.

Explanation:
the erosion or disintegration of rocks, building materials, etc., caused by chemical reactions (chiefly with water and substances dissolved in it) rather than by mechanical processes.Chemical weathering is caused by rain water reacting with the mineral grains in rocks to form new minerals (clays) and soluble salts. These reactions occur particularly when the water is slightly acidic.Name the four processes involved in chemical weathering. Answer: These are solution, carbonation, oxidation and hydration.Rainfall and temperature can affect the rate in which rocks weather. High temperatures and greater rainfall increase the rate of chemical weathering. ... Minerals in a rock buried in soil will therefore break down more rapidly than minerals in a rock that is exposed to air.
Explanation:
One of the reasons rocks look so varied in their appearance is because they are subjected to chemical weathering, which is the process by which rocks are broken down by chemical reactions. In this lesson, you will learn about the different types of chemical weathering and how exposure to things such as water, oxygen, carbon dioxide and acids can alter the minerals found in rocks.
We mentioned that chemical weathering is a way in which rocks get broken down. But, it is important to emphasize that because there is an actual chemical change taking place, rocks are not just crumbled into smaller rocks; they are actually being chemically altered. In other words, after chemical weathering, we end up with a different substance than the one we started with.
Different types of chemical weathering are:
•Oxidation
•Hydrolisis
•Carbonation
Chemical weathering increases as: Temperature increases: Chemical reactions proceed more rapidly at higher temperatures. For each 10 degrees C increase in average temperature, the rate of chemical reactions doubles. Precipitation increases: More water allows more chemical reactions.
