Study Fig. 4.1, which shows the thermometers that are kept in a Stevenson screen and Table 4.1 (Insert), a relative humidity table.

1. (a)(i)State the temperature range. Show your calculation.[2]
2. (a)(ii)With the help of Table 4.1, state the relative humidity. Show your calculation.[2]
3. (a)(iii)Which thermometer cannot be used to read the current temperature?[1]
4. (b)(i)The thermometers are kept in a Stevenson screen. How would the readings be affected if the thermometers were exposed to direct sunlight?[1]
5. (b)(ii)What feature of a Stevenson screen allows air to circulate while still protecting the thermometers from wind?[1]
6. (b)(iii)In the northern hemisphere the door of the Stevenson screen faces north. How does this help ensure accurate temperature readings?[1]
