PLEASE BHAI MARK AT BRAINLIESTS ANSWER PLEASE BRO HIIIIIIIIIIII

Explanation:

Weathering is happening all around the world, all the time. When a chemical reaction is the cause, it’s called chemical weathering. To find out how it happens and learn more fun chemical weathering facts, explore some famous examples of the phenomenon. And remember, chemical weathering doesn’t happen alone! It has friends like physical and biological weathering helping out, too.When it comes to chemical weathering, it’s all about chemistry. By looking at the term “chemical weathering,” you can see that a chemical reaction causes something to break down or “weather.” That “something” is rocks and minerals.

In chemical weathering, rocks and minerals are reacting to acids, oxygen, carbon and water. That’s why no two rocks ever look exactly the same. It’s also the reason that we have those awesome looking caves and unique rock formations all over the world.

While chemical weathering creates nifty formations, the way it breaks down rocks also causes fractures in ancient structures like the Great Sphinx of Egypt. It also causes the surface to break down on gravestones.

Types of Chemical Weathering

To truly understand chemical weathering and how it works, you need to look at examples of the different types of chemical weathering. Not all reactions that lead to chemical weathering happen or work quite the same way.

You also have to remember that chemical weathering types can work separately, but they often work together to create landforms and break down minerals. Check out how carbonation, oxidation, hydration, hydrolysis and acidification work.

Answer 2

Answer:

Answer:1. Hydrolysis:

Answer:1. Hydrolysis:It is the chemical breakdown of a substance when combined with water.

Answer:1. Hydrolysis:It is the chemical breakdown of a substance when combined with water. 2. Oxidation:

Answer:1. Hydrolysis:It is the chemical breakdown of a substance when combined with water. 2. Oxidation:Oxidation is the reaction of a substance with oxygen.

Answer:1. Hydrolysis:It is the chemical breakdown of a substance when combined with water. 2. Oxidation:Oxidation is the reaction of a substance with oxygen.3. Carbonation:

Carbonation is the mixing of water and carbon dioxide to make carbonic acid.

4. Hydration:

Hydration is a type of chemical weathering where water reacts chemically with the rock, modifying its chemical structure.

5. Dissolution:

Dissolution equally means leaching. It the process by which the rocks are dissolved when exposed to rainwater.
