The slow process of conversion of dead vegetation into coal is called

Options

A. carbonisation
B. oxidation
C. decomposition
D. distillation

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks for the term used to describe the slow process of converting dead vegetation into coal.

2. **Identifying the Process**: The process by which dead vegetation transforms into coal is a natural phenomenon that occurs over a long period of time. This process involves the accumulation of plant material, which undergoes physical and chemical changes.

3. **Recognizing the Correct Term**: The correct term for this slow conversion process is **carbonization**. Carbonization involves the decomposition of organic matter in the absence of oxygen, leading to the formation of coal.

4. **Evaluating Other Options**:
- **Oxidation**: This process involves the addition of oxygen or the removal of hydrogen from a substance, which is not related to the formation of coal from dead vegetation.
- **Decomposition**: While this refers to the breakdown of complex organic matter into simpler substances, it does not specifically refer to the formation of coal.
- **Distillation**: This is a method of separating components of a mixture based on differences in boiling points, which is unrelated to the process of coal formation.

5. **Conclusion**: After evaluating all the options, we conclude that the correct answer is **carbonization**.

**Final Answer**: The slow process of conversion of dead vegetation into coal is called **carbonization**.
