Which among the following process is not involved in water cycle?

Options

A. Melting
B. Evaporation
C. Sublimation
D. Condensation

Explanation

To determine which process is not involved in the water cycle, let's analyze the options provided and understand the processes related to the water cycle.

### Step-by-Step Solution:

1. **Understanding the Water Cycle**: The water cycle consists of various processes that describe how water moves through the environment. It includes processes like evaporation, condensation, melting, and freezing.

2. **Identifying the Processes**:
- **Melting**: This process involves ice (solid) turning into water (liquid). It is part of the water cycle as it contributes to the flow of water.
- **Evaporation**: This is the process where water (liquid) turns into vapor (gas). It is also a key part of the water cycle.
- **Condensation**: This is when water vapor (gas) cools down and turns back into liquid water. This is crucial for cloud formation and precipitation in the water cycle.
- **Freezing**: This process involves water (liquid) turning into ice (solid). It is part of the water cycle as well.

3. **Understanding Sublimation**:
- **Sublimation**: This is a process where a solid (like ice or camphor) turns directly into gas without passing through the liquid state. For example, camphor can sublimate when heated.

4. **Analyzing the Options**:
- From the processes listed:
- Melting is involved in the water cycle.
- Evaporation is involved in the water cycle.
- Condensation is involved in the water cycle.
- **Sublimation** is not typically considered a part of the water cycle as it does not involve the liquid state of water.

5. **Conclusion**: Therefore, the process that is not involved in the water cycle is **sublimation**.

### Final Answer:
The process that is not involved in the water cycle is **sublimation**.
