Two forms of energy in which solar energy manifests itself is

Options

A. tidal energy
B. ocean thermal energy
C. wind energy
D. Both (1) and (2)

Answer

To answer the question about the two forms of energy in which solar energy manifests itself, we can follow these steps:

### Step 1: Understand Solar Energy
Solar energy is the energy that comes from the sun. It can be converted into various forms of energy that can be harnessed for human use.

### Step 2: Identify Forms of Energy
We need to identify two specific forms of energy that are derived from solar energy. The options provided are:
1. Tidal Energy
2. Ocean Thermal Energy
3. Wind Energy
4. Both A and B

### Step 3: Analyze Each Option
- **Tidal Energy**: This is generated by the gravitational pull of the moon and the sun on the Earth's oceans. While solar energy indirectly influences tides, it is not a direct manifestation of solar energy.

- **Ocean Thermal Energy**: This form of energy is derived from the temperature difference between the warmer surface water of the ocean (heated by the sun) and the colder deep water. This is a direct manifestation of solar energy.

- **Wind Energy**: Wind energy is generated by the movement of air, which is caused by the uneven heating of the Earth's surface by the sun. This is also a direct manifestation of solar energy.

### Step 4: Conclusion
Based on the analysis, both Ocean Thermal Energy and Wind Energy are forms of energy that directly result from solar energy. Therefore, the correct answer to the question is **D: Both A and B**.

### Final Answer
The two forms of energy in which solar energy manifests itself are:
1. Ocean Thermal Energy
2. Wind Energy
