APPROACHES TO ASSESSMENT A/S
A skills question – not passed by QPEC
a) Use Figure 1 to describe the projected
annual mean precipitation change
between 1980-1999 and 2080-2099.
Looking for:
• identification of pattern
• use of the data on the map
Increase in rainfall on South Island (1)
over 15% in southwest (1). Areas of
decrease on west coast (1) -2.5 % and
Above (1)
Have to consider mark given (5) – about 6
minutes plus time to analyse resource
