Replacement of original hard parts of even the soft tissues of the organisms by minerals is known as

Options

A. Compression
B. Petrification
C. Moulds
D. Amber

Answer

To answer the question, "Replacement of original hard parts of even the soft tissues of the organisms by minerals is known as," we will analyze the options provided and identify the correct term.

### Step-by-Step Solution:

1. **Understanding the Options**:
- **Compression**: This refers to a type of fossilization where the organism is compressed under layers of sediment, preserving its shape but not replacing its material with minerals.
- **Petrification**: This process involves the replacement of the original organic material of an organism with minerals, effectively turning it into stone. This can occur in both hard parts (like bones) and soft tissues.
- **Moulds**: Moulds are impressions left by organisms in sediment, where the original material has decayed, but they do not involve mineral replacement.
- **Amber**: This is fossilized tree resin that can preserve organisms trapped within it, but it does not involve the replacement of tissues with minerals.

2. **Identifying the Correct Answer**:
- Among the options, **petrification** is the only process that specifically describes the replacement of both hard and soft tissues of organisms with minerals. This process can involve various minerals such as silica, calcium carbonate, or iron.

3. **Conclusion**:
- The correct answer to the question is **petrification**.

### Final Answer:
The replacement of original hard parts of even the soft tissues of the organisms by minerals is known as **petrification**.
