b. where - epicentre and effected areas
The epicentre and effected area was Christchurch
c. casualties
The Earthquake death toll reaches 145       
d. major damage

I think that the New Zealand Earthquake is a horrible and disastrous event that rarely occurs and should be forgotten about. Overall i hope that all the people in need of assistance from the Earthquake are helped and treated for whatever condition they are in. Also i hope that all the people missing are found.

1.6 Questions



1. The difference between climate and weather is that Climate is the pattern of weather that is expected in a particular place as weather is the temperature and what whether or not it is raining, sunny, cloudy, snowing, hailing, etc.


2. latitude affects climate because the closer you are to the equator the smaller the area that needs to be heated so it is hotter.
3. Australia is dominated by high pressure with low pressure in the north during summer and in the south during winter.
4. The normal circulation pattern in the Pacific Ocean brings rain to Australia.
5. The influence of relief on climate As altitude increases, air becomes thinner and is less able to absorb and retain heat.

Year 9: Australia's Large Coastline

























Positives
- More area to investigate, meaning that scientists can study more species in a larger 
area
- More control
- Hard for other countries to attack due to all the water surrounding Australia 
Negatives
- Other countries could attack from all areas around Australia
- Resources need to be maintained
- Need to control all the animals in the ocean and on land
