Which process is used to convert seawater to freshwater and can involve heat or membranes?

• A. Desalination
• B. Distillation
• C. Reverse Osmosis
• D. Aquifers

Answer: (A)

Desalination is the process of removing salts from seawater to produce freshwater. It encompasses methods that use heat (such as distillation, where seawater is boiled and the resulting vapor is condensed as freshwater, leaving salts behind) and methods that use membranes under pressure (such as reverse osmosis, where water is forced through a semi-permeable membrane that blocks salts). The clue that the process can involve heat or membranes points to desalination as the broad category that includes both approaches. Distillation is a specific heat-based technique within desalination, while reverse osmosis is a membrane-based technique within the same umbrella. Aquifers, on the other hand, are underground groundwater sources, not a desalination process.
