Rainfall

One sample question with the full working. 2 more in the app, with instant feedback and repair sessions for the traps below.

Rain caused when moist air is forced to rise over mountains is

Arelief (orographic) rain
Bconvectional rain
Cfrontal rain
Dacid rain

Show the answer and working

Answer: A

Mountains → relief rain.

Trap B Confuses types of rainfall: Convectional: intense surface heating (equatorial afternoons). Relief/orographic: air forced over highlands (windward wet, leeward rain shadow). Frontal/cyclonic: warm air rises over cold air (temperate).

Trap C Picks a closely related feature or term: Learn related features as contrasting pairs: how each forms and what it looks like.

Trap D Environmental hazard misconceptions: Desertification: overgrazing, deforestation, bush burning, drought. Soil erosion control: afforestation, contour ploughing, terracing, cover crops. Floods: heavy rain, blocked drains, deforestation.

Traps in Rainfall

Confuses types of rainfall
Convectional: intense surface heating (equatorial afternoons). Relief/orographic: air forced over highlands (windward wet, leeward rain shadow). Frontal/cyclonic: warm air rises over cold air (temperate).
Picks a closely related feature or term
Learn related features as contrasting pairs: how each forms and what it looks like.
Environmental hazard misconceptions
Desertification: overgrazing, deforestation, bush burning, drought. Soil erosion control: afforestation, contour ploughing, terracing, cover crops. Floods: heavy rain, blocked drains, deforestation.
Confuses ocean currents and their effects
Cold currents (Canary, Benguela, Humboldt/Peru, Labrador) cool coasts and contribute to coastal deserts (Namib, Atacama) and fog. Warm currents (Gulf Stream/North Atlantic Drift, Guinea, Kuroshio) warm coasts. Mixing of warm and cold water favours plankton and fishing grounds.
Pressure and wind errors
Winds blow from HIGH to LOW pressure, deflected by the Coriolis force (right in N hemisphere). Trade winds blow toward the ITCZ/doldrums; westerlies blow poleward.
