6. DIURNAL RANGE OF TEMPERATURE.
• The difference between the maximum and minimum
temperatures in a day is called Diurnal range of
temperature.
Diurnal range of temperature = Maximum temperature –
Minimum Temperature
7. DIURNAL RANGE OF TEMPERATURE.
Diurnal range of temperature =
Maximum temperature – Minimum
Temperature
= 33 – 28
= 5°c
