Asked by shaunm to Dustin, James on 25 May 2012.
Keywords: core, earth
The Earth is separated into three broad layers called the core, mantle and crust. The crust is what we stand on and includes the top-soils and bedrock. It is mostly solid and is between 5 and 70km thick in some places.
The Mantle starts where the crust ends and then goes for about 3000km. It is the thickest layer of the the Earth’s structure and is molten.
The innermost part, the core starts after the mantle and its centre is another 1200 km in from the border with the mantle. The core is a solid lump of iron and nickel.
That looks like a pretty good answer.
Well if this is the last question i have with you, thanks for all the questions it has been a lot of fun.
All the best and enjoy school
