Rising air expands, cools, and may condense. Exam tip: remember rising, cooling, and cloud formation together.
View question detailsSaturated air cannot hold extra water vapour. Exam tip: link extra vapour with condensation.
View question detailsWater droplets and ice particles form when water vapour cools. Exam tip: connect cloud particles with condensation.
View question detailsWith heat, water molecules move faster and become vapour. Exam tip: understand heat as energy for evaporation.
View question detailsNear sea coasts, water sources are large, so humidity can be higher. Exam tip: remember higher humidity near water sources.
View question detailsDesert regions have very limited rivers, lakes, and other surface-water sources. Consequently, less water vapour enters the atmosphere through evaporation, so humidity is generally low. Regular moist sea winds or heavy rainfall would increase humidity, not reduce it. Exam tip: link humidity mainly with the amount of water vapour supplied by evaporation.
View question detailsWhen droplets become larger and heavier, they fall as rain. Exam tip: link heavy droplets with rainfall.
View question detailsWater vapour is not visible, but its effects are visible. Exam tip: treat clouds, dew, and fog as effects of water vapour.
View question detailsIn fog, tiny droplets scatter light and reduce visibility. Exam tip: remember fog through tiny water droplets.
View question detailsWhen humidity is high, sweat dries slowly. Exam tip: remember the role of humidity in human comfort.
View question detailsWater vapour supports processes like cloud formation and rainfall. Exam tip: remember water vapour as an important weather component.
View question detailsHeat and dryness both increase evaporation. Exam tip: link hot and dry conditions with fast evaporation.
View question detailsCondensation can turn invisible water vapour into visible droplets. Exam tip: link visible moisture with condensation.
View question detailsEvaporation sends water from the surface into the atmosphere as vapour. Exam tip: remember the direction.
View question detailsCondensation changes water vapour into droplets and clouds. Exam tip: remember condensation as a cloud formation step.
View question detailsThese three processes are key links of the water cycle. Exam tip: remember the steps of the water cycle in order.
View question detailsHigh relative humidity shows that air is near its water vapour holding capacity. Exam tip: understand a high percentage as near saturation.
View question detailsWater from a water body continuously changes into vapour and enters the air. Exam tip: remember water sources as sources of humidity.
View question detailsIn the morning, water vapour condenses on cool surfaces to form dew. Exam tip: treat droplets on leaves as an example of dew.
View question detailsIn cloud formation, water vapour cools and changes into droplets. Exam tip: connect cloud formation with condensation.
