Major source of mineral in soil is the

Options

A. parent rock from which soil is formed
B. plants
C. animals
D. bacteria

Explanation

**Step-by-Step Solution:**

1. **Understanding Soil Formation**: Soil is formed from the weathering of rocks. This process involves the breakdown of large rocks into smaller pieces.

2. **Weathering Process**: The breakdown of rocks into smaller fragments is known as weathering. This can occur due to various factors such as temperature changes, water, wind, and biological activity.

3. **Minerals in Rocks**: The large rocks that undergo weathering contain various minerals. These minerals are essential components of the soil.

4. **Transfer of Minerals to Soil**: As the rocks break down into smaller pieces, the minerals contained within these rocks are released and incorporated into the soil.

5. **Role of Organisms**: While bacteria, plants, and animals contribute to soil formation and the weathering process, the primary source of minerals in the soil is the parent rock from which the soil is derived.

6. **Conclusion**: Therefore, the major source of minerals in soil is the parent rock, which undergoes weathering to form soil.

**Final Answer**: The major source of minerals in soil is the parent rock.
