Qn 1: Which one of the following types of clouds rarely form at heights lower than 5000m?

stratus cumulus cirrus nimbostratus

Qn 2: Rains falls because

clouds bump into mountains and so burst
moist air rises and condenses
clouds become too cold to holf water
clouds bump into each other and so burst

Qn 3: When we talk about 'weather', we are:

Temperature, precipitation, wind, pressure and sunshine
Temperature and rainfall
Temperature, rainfall and pressure
Temperature, rainfall and wind

Qn 4: Water vapour is turned into water droplets by the process of

evaporation convection liquefaction condensation

Qn 5: Wind is the movement of air from

areas of lower pressre to areas of low pressure
areas of high pressure to areas of higher pressure
areas of low pressure to areas of high pressure
areas of high pressure to areas of low pressure

Qn 6: Which one of the following is commonly associated with a tropical storm?

a central area of calm
a central area of high pressure
wind speeds of 20 km/h
persistent drizzle

Qn 7: In equatorial lowlands, the combination of rising temperatures and increasing humidity during the morning and earyl afternoon are often followed by heavy rain in the late afternoon. What is this type of rainfall called?

conventional rain
monsoonal rain
relief rain
frontal rain

Qn 8: In tropical areas, air rising by convection through the atmosphere causes a thick layer of clouds to form. The base of these clouds indicate the altitude at which

temperature inversion occurs
the rising air meets descending air currents
the air can rise no further
the rising air has been cooled so that water vapour has condensed

Qn 9: During the formation of cloud, in what order do the processes of condensation, evaporation and saturation take place?

condensation - evaporation - saturation
evaporation - condensation - saturation
saturation - condensation - evaporation
condensation - saturation - evaporation

Qn 10: If a mass of air flows down into a valley from high mountains, it tends to become

cooler and less moist
warmer and less moist
cooler and more moist
warmer and more moist
