# Factual anchors

## F1

Liquid water can change to invisible water vapour by evaporation; boiling is not required.

Sources: B1, U1, S1

Limit: General process fact; does not establish how much/time or cause of a particular puddle loss.

## F2

Condensation changes vapour into liquid droplets; clouds can include droplets and/or ice, distinct from invisible vapour.

Sources: B1, U2, S1

Limit: General process fact; a wet container alone does not prove condensation ruled out all other causes.

## F3

Precipitation is water falling from clouds in forms such as rain, snow or hail.

Sources: U3, B1

Limit: General process; not rain from a cup or a cloud bursting bag/timetable.

## F4

Water can follow multiple paths among sky, landscape and ocean; a selected simple model has no fixed beginning or forecast.

Sources: N1, U4

Limit: Selected model links are not an exhaustive water-budget or weather model.

## F5

Council names the Barrage source for Glenmore plant in the Rockhampton/Gracemere supply example.

Sources: L1, L2

Limit: Narrow published system fact with indexed retrieval; no household quality/connection or capacity/count claim.

## Failures retained

USGS wholepage opens timed out and Council direct page returned 403; narrow facts use actually retrieved official indexed sections. No wholepage/video/current live classroom result is implied. Old guessed Bureau/GeoscienceAustralia/Hub URLs failed and are not used. The Council Barrage fact sheet contains conflicting capacity and user counts, so no such figures are included. The Waikato article's eccentricity/tilt wording is excluded. Nobody copied article imagery, a video, the official model graphic or third-party photographs.
