⚠️ Common Misconceptions
Misconception 1: "Clouds are made of water vapour"
Clouds are actually made of tiny liquid water droplets (or ice crystals at high altitude), not water vapour. Water vapour is an invisible gas. Condensation converts water vapour into the visible liquid droplets that form clouds. You cannot see water vapour — if you can see it, it has already condensed.
Misconception 2: "Only evaporation puts water into the atmosphere"
Many students forget that transpiration from plants is also a major source of water vapour in the atmosphere. In heavily forested areas, transpiration can contribute more water vapour to the local atmosphere than evaporation from water surfaces. Both processes must be mentioned in exam answers about how water enters the atmosphere.
Misconception 3: "Percolation and precipitation are the same thing"
These are two completely different processes. Precipitation is water falling from the atmosphere (rain, snow, etc.) — it moves downwards through the air. Percolation is water soaking down through soil into the ground — it moves downwards through rock and soil. One is atmospheric; the other is geological.
