The Earth's core (there is widespread agreement that there is an inner core and outer core) is made up of mainly iron and nickel. The Earth's mantle which rides atop the core is made of ultramafic rock that is believed to be significantly richer in iron and magnesium than the solid crust above.
The Earth's crust could be considered part of the interior, since the continental exolayer that we live on is largely covered with crushed and finely crushed rocky material such as sands mixed with organic material to form soils. The actual crust is only occasionally exposed in outcroppings, and in mountains where the crust has been upthrust by tectonic plate collisions.

It is warmed by geothermal energy which is created by RADIOACTIVE DECAY http://en.wikipedia.org/wiki/Geothermal_(geology)

I think so... Pennies are made out of copper with some zinc (?) on the inside. Since copper is a metal I would assume that we have a limited amount of it here on Earth. Although, I highly doubt we are going to run out of it any time soon!

each layer in earth has diffrent material that is cuse diffrent propertis. natural or man made Wave when it come from inside of the earth show difftent propertis .this is main reason of layering earth .
Deep inside the earth, where there is intense heat and pressure.
The earth is made of mostly rock because the crust is rock and the inside such as the core is molten rock such as lava.
The heat from inside Earth gets dissipated into space on the surface, so you would expect the surface to be colder than the inside, which is farther from the surface.Also, there are differences in heat transport inside Earth, simply because different parts of the Earth are made up of different materials.

The materials that formed the Earth are in fact OLDER than the Earth, because they were around BEFORE the Earth was formed. The Elements that you are made of were formed inside STARS before the Earth ever existed.
earth
Intrusive rock. The prefix in-helps to remember that it is made inside the earth.
