The white cliffs of Dover, England, are made of chalk, a form of limestone. Limestone is a type of rock that is made up of bits of animal shells. Over millions of years these shells collected on the ocean floor. As layers of shells and mud built up, the lower layers slowly hardened into limestone. Limestone is found all over the world. Some of this sediment might form fossil fuels, such as coal, oil, or natural gas, which release carbon back into the atmosphere when the fuel is burned. The carbon cycle is vital to life on Earth.
