# The mountain-model visitor

Made-up story. At a pretend mountain exhibition, a visitor asks, “How could lake water reach the sea as rain?” The model card lists lake liquid → evaporation → invisible water vapour in air → condensation → cloud droplets → precipitation → ocean water. A second branch shows precipitation to land. No amount, travel time or weather forecast is supplied. The visitor needs a short explanation of the possible process, not a promised rain date. Choose a written, drawn, signed, spoken, dictated or typed response.

## Four questions

1. Answer this visitor using the three process names.

2. What changes in the second branch?

3. Who are you helping, and with what question?

4. Give one useful limit.
