The energy available due to the difference in the temperature of water at the surface of the ocean and at deeper levels is called

Options

A. tidal energy
B. wind energy
C. solar energy
D. none of these

Answer

To solve the question regarding the energy available due to the difference in temperature of water at the surface of the ocean and at deeper levels, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Concept**: The question refers to a specific type of energy that is derived from the temperature difference in ocean water. This concept is related to ocean thermal energy.

2. **Identifying the Energy Type**: The energy that is generated from the temperature difference between the warm surface water and the cold deep water in the ocean is known as Ocean Thermal Energy Conversion (OTEC).

3. **Clarifying the Options**: The question provides options such as tidal energy, wind energy, solar energy, and none of these. We need to identify which of these relates to the temperature difference in ocean water.

4. **Evaluating Each Option**:
- **Tidal Energy**: This is energy generated from the rise and fall of tides, not temperature differences.
- **Wind Energy**: This is generated from wind movement, unrelated to ocean temperature.
- **Solar Energy**: This is energy from the sun, not specifically from ocean temperature differences.
- **Ocean Thermal Energy**: This is the energy derived from the temperature difference in ocean water.

5. **Conclusion**: The correct answer to the question is Ocean Thermal Energy, which is not listed among the options provided. However, if we had to choose from the given options, we would conclude that none of the listed options accurately describe the energy derived from temperature differences in ocean water.

### Final Answer:
The energy available due to the difference in the temperature of water at the surface of the ocean and at deeper levels is called Ocean Thermal Energy. Since this option is not provided, the answer would be "none of these."
