The process of removing salt from sea water is called

Options

A. Desalination
B. Dehydration
C. Decantation
D. Re-hydration

Answer

**Step-by-Step Solution:**

1. **Identify the Process**: The question asks about the process of removing salt from seawater. This process is commonly known in scientific terms.

2. **Define the Process**: The correct term for the process of removing salt from seawater is "desalination."

3. **Explain How Desalination Works**: Desalination typically involves a technique called reverse osmosis. In this method, seawater is passed through a semi-permeable membrane.

4. **Describe the Mechanism**: The semi-permeable membrane allows only smaller water molecules to pass through while retaining salt and other impurities. This is done under high pressure.

5. **Conclusion**: Therefore, the answer to the question is that the process of removing salt from seawater is called "desalination."
