Generally it's made of graphite. Graphite is a substance made of carbon. The carbon atoms are bonded together in a particular way that allows "sheets" of graphite to break off easily. When you write something, some of these sheets break off and end up on your paper.
glycose helps pops off a carbon and generates energy (krebs cycle)
Carbon Dioxide
Carbide is a compound made of carbon and another element, typically a metal such as tungsten, titanium, or calcium. The combination of carbon and the metal creates a very hard and wear-resistant material that is used in various applications, such as cutting tools and abrasives.
The Indo-Australian Plate is one of the major tectonic plates covering the Indian Ocean and parts of Australia. It is the second-largest tectonic plate, with an area of about 58 million square kilometers. It is made up of two separate plates that are gradually moving apart.
no. earthquakes are set off by sudden movements in the earths crust
rocks
It is made of graphite, or carbon.
The major heat source of Earth's crust is residual heat from the planet's formation and radioactive decay of elements like uranium, thorium, and potassium within the Earth's interior. This heat is responsible for driving processes like mantle convection, plate tectonics, and volcanic activity on the Earth's surface.
carbon dioxide + water
steel, with durible titanuim palting to protect it from breaking up in earths atmosphere
Carbon fibre is generally greater than 95% carbon. Carbon fibre is made from a spun material that is very rich in carbon. It is usually a material called Polyacrylonitrile (PAN) or sometimes pitch, an oil derivative. These are heated in an inert atmosphere to drive off the other atoms, which leaves a fibre made almost entirely of carbon.
leaving the crust on gives you more nutrition

pizza dough ... haha very funny ( somebody else wrote that ) http://mediatheek.thinkquest.nl/~ll125/en/crust.htm
Water.
I'll eat your pizza crust for you.The crust was all burned up.The crust of the earth is a very interesting subject.When I eat a sandwich, I always cut off the crust.
