Choose the correct answer :
A sedimentary type of biogeochemical cycle is :

Options

A. Carbon
B. Hydrologic
C. Nitrogen
D. Sulphur

Answer

To solve the question, "A sedimentary type of biogeochemical cycle is:", we can follow these steps:

### Step-by-Step Solution:

1. **Understand Biogeochemical Cycles**: Biogeochemical cycles are processes that involve the movement of elements and compounds through biological, geological, and chemical processes. They can be categorized into two types: gaseous and sedimentary cycles.

2. **Identify the Types of Cycles**:
- **Gaseous Cycles**: These cycles involve elements that exist in the atmosphere and can be found in gaseous forms. Examples include the carbon cycle and nitrogen cycle.
- **Sedimentary Cycles**: These cycles involve elements that are primarily found in the earth's crust and do not have significant gaseous phases. Examples include the phosphorus cycle and sulfur cycle.

3. **Analyze the Options**:
- **Carbon Cycle**: This is primarily a gaseous cycle as carbon exists in the atmosphere as CO2.
- **Hydrologic Cycle**: This cycle involves water and is not a sedimentary cycle.
- **Nitrogen Cycle**: This cycle involves nitrogen, which is also present in the atmosphere and is considered a gaseous cycle.
- **Sulfur Cycle**: This cycle involves sulfur, which can exist in sedimentary forms and is primarily found in the earth's crust.

4. **Conclusion**: Based on the analysis, the only option that represents a sedimentary type of biogeochemical cycle is **Sulfur**.

### Final Answer:
The correct answer is **D. Sulfur**.
