Model Answer
Water is considered a renewable resource because it is continuously renewed and recharged through the hydrological cycle. Freshwater obtained from surface run-off and groundwater is constantly replenished as all water moves within this cycle — through evaporation, condensation, and precipitation — ensuring its availability is restored over time.

Explanation
- The key phrase examiners look for is "hydrological cycle" — always name it.
- Mention that freshwater (surface run-off + groundwater) is continually renewed/recharged — this directly addresses "despite being consumed."
- Do not confuse renewable with unlimited; scarcity still exists. You don't need to elaborate on scarcity here unless asked.
- 2 marks = 1 mark for the concept of renewal + 1 mark for naming/explaining the hydrological cycle mechanism.
