I'm screwed, Please someone help with my Science Homework!!

[PsychicHeart]

I am so screwed.
For a science project (due in about 3 days) i need to know the composition of all the earth's layers.
That's the % of everything that makes up the earths Inner Core, Outer Core, Mantle, Crust, everything!
I've checked almost every website on the topic,
called so many friends it's not funny,
but to no avail.
If anyone knows a website where this information may be obtained or has a book on the topic or knows at least some of this information off the top of their head that'd be great.
Thanks,
Fb.
PS: Please don't burn me at the stake like you do on most of my pointless posts, this is serious!!!

I'm not trying to bring you down here, but don't they list that stuff in your schools textbooks? If not you could try an encyclopedia at the library maybe...

Search wikipedia, I'm pretty sure you'll find it there. If not, go the local library and get a geology or a astronomy textbook, those should have it as well.

Just did a quick browse and have this - http://en.wikipedia.org/wiki/Earth

and links off to details on:
the crust - http://en.wikipedia.org/wiki/Crust_%28geology%29
the mantle - http://en.wikipedia.org/wiki/Mantle_%28geology%29 Composition of Earth's mantle can be found on that link

This site may also be worth a look

Hope this helps, just try to get things done or at least started as soon as you can, and maybe pay attention in class and perhaps ask your techer to point you to some outside reading at your local library.

Thanks guys,
i've got the mantle done now (thanks magnitz), so that's at least a start.
As for some of the other posts,
i've been to the library twice in the last 3 days,
and nothing.
I've checked my textbook just then, and found the crust's composition, but that's it.
And hey, i do pay attention in class!!
Cheers,
Fb.

You can't find -anything- in the library on it? I'm stunned o_O That must either be the worst library in existance or you just didn't find the right books.

1.  Google  is your friend.  Quit using that crappy M$N stuff.

2.  Third item in above search is proably what your looking for.  I can't believe you looked very hard.

First site listed, google search +composition +earth +crust displays percentage of chemical composition for all layers, but every link on the page has some information about it. 

Procrastination is not your friend.

Another link you might find useful.
