Not too sure what to do for this when revising at home. Today I'm trying to learn the faults in NZ and what they are doing.

Underneath the North Island the Pacific Plate is sub-ducting the Australian Plate, where as, just south of the South Island this flips, and the Australian Plate is now sub-ducting the Pacific Plate.

Evidence and records have been shown that deeper focus earthquakes under the North Island have formed a well defined seismic zone running from the Malborough Fault in a north easterly direction. In this seismic zone, deeper focus earthquakes have been occurring more in the North of compared to more shallower focus earthquakes happening more to the south east of this seismic zone (in Christchurch territory)

When looking at figure P1, hydrological events have just about increased the most. This could perhaps be linked to increasing climatological events (e.g. drought). A warmer climate would result in more heat rising and as a result more clouds and rain - so floods would become more frequent. Does this sound about right? I did do weather and climate for unit 3 but as you can probably tell I wasn't very good at it! :L

Think about the obvious hints they're giving you that they could ask questions on, like 'some people think there may be some links between the trends shown in the two sets of data' (that question is SOOO happening), and then work out how to answer it. For that one, you might need to do some statistical tests and work out a model answer for why temp increase could cause increase in extreme weather, but also reasons why there might not be a link (ie P1 is by an insurance company, so they DEFINITELY have a vested interest in extreme weather 'increasing' - they can raise people's premiums, and they could be including teeny tiny floods because they don't specify what a natural disaster is).

I did spearmans rank on P1 & P2, they are not linked whatsoever

kinda confused on what http://www.christchurchquakemap.co.nz/ shows and not sure what we are suppose to note from the website... and how it can be asked in a question

what graph would you say would be most suitable for figure p2? I originally thought a histogram although im not too sure :/

Im thinking just a bar graph? This allows you too see a trend, e.g. if the years are getting hotter (shown my the bars height increasing through the years) plus with a bar graph you can include years which dont have data and skill create the graph.

I think the first question will be "What graphing technique would you use to present the data in P2"

I would mention the bar graph and how you can see trends. I would also explain how i would create it and what my axis would be. I would also talk about why it is better than another technique (for this try to think of another technique which obviously wouldnt work like a pie graph.)
One final thing I think I would mention is that there is a lot of talk about P1 & P2 being linked, so by drawing a bar graph you could have it the same scale as P1 and in theory you could 'overlay' the two graphs to make looking for similarities or trends easier...

These are just my thoughts, hope they made sense.

Anyone know the year regarded as the start of reliable climate records? (question in zigzag booklet but I can't find the answer)

I really really dont understand how you're supposed to revise for this exam!! Any advice??
