An inexhaustible resource is

Options

A. wind energy
B. solar energy
C. hydrothermal energy
D. tidal energy

Answer

To determine what an inexhaustible resource is, we can follow these steps:

### Step 1: Define Inexhaustible Resources
An inexhaustible resource is defined as a resource that exists in unlimited supply and cannot be exhausted or depleted, even with human exploitation.

### Step 2: Identify Examples of Inexhaustible Resources
Common examples of inexhaustible resources include:
- Solar energy
- Wind energy
- Hydrothermal (geothermal) energy
- Tidal energy

### Step 3: Analyze the Options Provided
The question provides four options:
1. Wind energy
2. Solar energy
3. Hydrothermal energy
4. Tidal energy

### Step 4: Evaluate Each Option
- **Wind Energy**: This is generated from the movement of air and is considered inexhaustible.
- **Solar Energy**: This is derived from sunlight and is also inexhaustible.
- **Hydrothermal Energy**: This refers to geothermal energy, which is derived from the heat within the Earth and is inexhaustible.
- **Tidal Energy**: This is produced by the gravitational pull of the moon and sun on Earth’s water bodies, making it inexhaustible as well.

### Step 5: Conclusion
All the options listed (wind energy, solar energy, hydrothermal energy, and tidal energy) are inexhaustible resources. Therefore, the answer to the question is that all of these options are correct.
