Mapping

1. What is it about the pressure system stalled over Australia that relates to the weather over the next 4 days?

 The pressure system stalled over Australia is a high pressure system which is lingering over South Australia but also a serperate high pressure system approaching for the east meaning that warm sunny weathers will be affecting these areas.

2. What is the air pressure in each of the next 4 days for each of the capital cities? How does this correspond with the predicted weather for these cities?

Sydney - 1016 1022 1018 1017
Melbourne - 1024 1016 1018 1024
Brisbane - 1017 1016 1017 1016
Darwin - 1017 1017 1016 1017
Perth - 1016 1018 1017 1020
Adelaide - 1018 1027 1020 1022
Hobart - 1024 1020 1022 1018
Canberra - 1024 1018 1017 1020

1. What is the contour interval (sometimes abbreviated CI)? Convert to metric
20ft so about 6m.

2. What is the scale of the map? Convert it into the metric system
 1:1000
3. What is the gradient of the line? Calculate in metric system.
869ft = 261m
2cm line = 20m
gradient = 13.05
