Question

Carbonisation is?
a. Slow conversion of dead vegetation into coal.
b. Deposition of soil
c. Falling of soil
d. None of these

Answer 1

Hint: Carbonization defines as the formation of coal or coke from the remains of plants. The process is the same as a reduction reaction, occurring in the atmosphere to maintain the ecosystem balance.

Complete answer:
> Option A:
The Slow conversion of dead vegetation into coal is called carbonisation. Yes, it is the true statement as the process of carbonization is the slow process by which the dead plants buried deep under the earth surface have become coal. Coal is usually made from the remains of dead plants and animals known as fossil fuel. A large amount of heat energy is also produced during burning of coke.

> Option B:
Deposition of soil is the process in which soil, rocks and sediments are kept on adding to form a landmass and landform.

> Option C:
Falling of soil is defined as the process in which earth materials are worn away and translocated by natural forces such as wind, water or air. It is also called soil erosion which is usually caused by natural calamities plus human activity such as flood, drought, and deforestation.

Hence, the correct answer is option (A).

Note: Carbonization is the term used for the conversion of organic materials into carbon and carbon containing substances and their residues through heating processes that occur in nature using large amounts of energy. The process of carbonization also occurs through distillation.
Always search for the answer by looking into the question first, as the carbonization is made up from two words carbon plus isation meaning carbon and formation. So, select the answer by understanding the formation of carbon in the process.
