Coal is a type of fossil fuel made from the remains of ancient plants that lived millions of years ago. Over time, these plant remains were buried and underwent chemical and physical changes to become coal.
Coal is the solid fossil fuel formed from the remains of swamp plants that grew millions of years ago.
coal. It is a sedimentary rock formed from the remains of plants that lived millions of years ago. Coal is burned to produce energy in power plants.
Coal is a natural resource formed from the remains of plants that died millions of years ago. These plants underwent decomposition and heat and pressure over time, which resulted in the formation of coal deposits.
Coal is a solid fossil fuel. It forms from the remains of plants that lived and died millions of years ago, and it is mined for energy production.
It powered the plants until they died millions of years ago, to eventually become coal.

The enrgey comes from plants 100's of millions of years ago
Fossil Fuels
Coal can last for millions of years, as it is a fossil fuel formed from the remains of plants that lived in swamps millions of years ago. However, once coal is mined and burned, its energy is used up and it cannot be reused.
They are the reason for coal. Millions of years ago, in the tropics, there were seedless vascular plants. When they died, they turned to coal.
Coal, gas and oil are three forms of non-renewable resources - which, laid down millions of years ago, can't be renewed.
i think its from the energy stored by plants that lived hundreds of millions of years ago.=]
