Questions 1.6

1. Climate is the pattern of weather that is expected in a particular place. Patterns of climate and vegetation are closely related because climate is the main factor that determines where plants can grow. Weather is short term and it is what is happening in the present time.
2. The Earth receives more of the Sun’s energy at the Equator than at the poles so temperatures are highest at the Equator and the temperatures decrease as latitude increases.
3. Typical summer weather map - low pressure in the north, high pressure in the south. Typical winter weather map - high pressure in the north, low pressure in the south.
4. Currents - Currents from nearer the poles bring cooler conditions and those from nearer the Equator bring warmer conditions.
5. Temperature decreases with height. Moist air that is forced to rise by mountains cools, and the water
vapour condenses, producing increased cloud cover and precipitation. Highland areas are cooler and wetter
than lowland areas.
6. a. Average climate statistics assist farmers to tell them when it is most suitable to plant their crops as they may want to plant them the month before a huge rainfall occurs. This also helps determine when to harvest their crops. For example you may need to plant in winter and the best time to harvest is the first of spring.  
b. Tourists may want to look at the forecast/ climate predicted if they are considering going away to a sunny place as they don't want it to rain.
7. Where there is a lot of vegetation, forest and woodland can be very hot and humid. Then there is the places where there is only a bit of shrub land, pasture and cropping and this is where there is sub tropical conditions, hot dry summer, warm dry winter.
8. a. Hobart- average of precipitation is 47.43 rainfall (mm) and the average temperature is 12.41 Celsius.
b. Darwin- average of precipitation is 142.4 rainfall (mm) and the average temperature is 27.59 Celsius. 
9. a. Alice Springs has the greatest temperature range as shown in source 1.29.
