yeah,i didnt get the mantle dynamics question aswell!so i had to guess and i put that convection currents are formed by radioacticvity in the mantle,,dunno if its right though!and for that other earthquake question,the reasons i put was:1)people might not trust the scientists 2)scientists dont know what is fully happening underneath the earth 3)and i cant remember!!

I found the paper okay :smile:

What did everyone put for how is nitrogen oxide formed in the engine?? I didn't really understand that as we haven't done about it so I just put 'Because the nitrogen in the fuel reacts with the air around it' aha :L I'm guessing that's wrong though :L

Yh I think the question was about gold's properties; I put its stronger (brittle) and has to go less process (less expense) what about u ? :smile:

I put '1) It's too soft when pure, and 2) it's too expensive and rare to make jewely out of 100% gold'

So would this count : HAs to go through more processes? + what did you put about sulfur dioxide (1st question) ??

How are you able to access that since when wkikpedia had been blacked out?

What you can do is put an m in the website so

http://en.wikipedia.org/wiki/Main_Page

becomes

http://en.m.wikipedia.org/wiki/Main_Page

Basically the mobile site is still working. Or alternatively put this at the end of the URL "?banner=none"

Therefore

http://en.wikipedia.org/wiki/Main_Page

becomes

http://en.wikipedia.org/wiki/Main_Page?banner=none

24 carat gold is something like 99.9% or 99% pure. As Gold is found in it's native element i.e. pure, it isn't that it's too rare it's just a matter of maleabilty and cost (which is why I highlighted part of it) Half can be considered correct the highlighted part I'm not sure. But I don't rem the exact question.
