Question: Which of the following is not an example of chemical weathering?

The correct answer is Corrosion. There are different types of chemical weathering processes such as solution, hydration, carbonation, oxidation, reduction, and biological. Hence corrosion is not a type of chemical weathering.

Which of the following is an example of chemical weathering?

C: Acid rain is an example of chemical weathering. When acidic chemicals are evaporated and fall as rain, they can have devastating effects on plant and animal life.

What are the 4 causes of chemical weathering?

The causes of chemical weathering are chemical reactions such as oxidation, carbonation, hydrolysis, and acid-base reactions.

Is Iron Oxide an example of chemical weathering?

Chemical Weathering – the transformation of rocks and minerals exposed to water and air into new chemical products. Role of Oxygen – rusting of an iron nail exposed to dampness and air is a simple example of chemical weathering. Iron oxide (hematite) is a product of weathering.

What are the 5 types of chemical weathering?

These factors cause elements to break down and dissolve or create new materials. There are five types of chemical weathering: carbonation, hydrolysis, oxidation, acidification, and lichens (living organisms).

What are the 4 types of weathering?

There are four main types of weathering. These are freeze-thaw, onion skin (exfoliation), chemical and biological weathering. Most rocks are very hard. However, a very small amount of water can cause them to break.

What are the 3 types of weathering?

There are three types of weathering, physical, chemical and biological.

What are some examples of chemical and mechanical weathering?

In chemical weathering, the rock reacts with substances in the environment like oxygen, carbon dioxide, and water to produce new substances. For example, iron in rock can react with oxygen and water to form rust, making the rock reddish and crumbly. During mechanical weathering, no new substances are produced.

Is acid rain chemical weathering?

The weathering of rocks by chemicals is called chemical weathering . … When acidic rainwater falls on limestone or chalk, a chemical reaction happens. New, soluble, substances are formed in the reaction. These dissolve in the water, and then are washed away, weathering the rock.

Is amphibole resistant to weathering?

Pyroxene, amphibole, magnetite, pyrite, and olivine are most susceptible to oxidation because they have high iron content. The ions released from silicate minerals in the weathering process are sodium, potassium, calcium, iron, and magnesium ions.

What are chemical weathering agents?

Chemical weathering changes the composition of a mineral to break it down. The agents of chemical weathering include water, carbon dioxide, and oxygen. Living organisms and humans can contribute to chemical weathering.

What are the 5 types of physical weathering?

There are 6 common ways in which physical weathering happens.
