Majority of the nutrients that are essential for plant and development become available to the roots

Options

A. Weathering of rocks
B. Condensation
C. Breakdown of rocks
D. Both (a) and ( c)

Answer

**Step-by-Step Solution:**

1. **Understanding Nutrient Availability**: The question asks about the majority of nutrients essential for plant development that become available to the roots. Nutrients are vital for various physiological functions in plants.

2. **Identifying Sources of Nutrients**: The primary source of nutrients for plants is the soil. Nutrients in the soil become available through various processes.

3. **Weathering of Rocks**: One of the key processes is the weathering of rocks. Weathering involves the breakdown of rocks into smaller particles and simpler molecules, which releases essential minerals and nutrients into the soil.

4. **Impact of Weathering on Soil Quality**: As rocks weather, they contribute to the mineral content of the soil, enhancing its nutrient value. This process increases the availability of essential nutrients for plant roots.

5. **Condensation**: The transcript mentions condensation, but it is clarified that condensation does not contribute to nutrient availability for plants. Instead, it is the weathering process that plays a significant role.

6. **Conclusion**: Based on the information, the correct answer is that the majority of essential nutrients for plant development become available to the roots primarily through the weathering of rocks.

**Final Answer**: The majority of the nutrients essential for plant development become available to the roots through the weathering of rocks.
