coal is like a solid carbon. Most of living thing's molecules is made up of complex carbon molecules. When this get buried the pressure very high. Therefore, solid carbon is formed
Coal takes millions of years to form from the pressure of dead plants and trees in swamps.
dead plants, intense heat, pressure and a lot of time. . . coal is not considered a renewable energy source because it takes millions of years to form
Coals are formed by plants, after millions of years they become coal.
Millions of years of pressure and heat turned decaying animals and plants into coal.
fossil fuel
They are called limited because they take millions of years to form and most probably no-one has millions of years to live.
Flowering plants are called angiosperms and overtime as climate changes plants must adapt and change to the environment. So over millions of years plants will look different.
Coal is a solid fossil fuel formed in ancient swamps from the remains of plants and animals under great heat and pressure over millions of years. A liquid fossil fuel formed in oceans from the remains of plants and animals under great heat and pressure of millions of years is called oil.
Coal takes millions of years to form from the pressure of dead plants and trees in swamps.
Giant Dinosaur Eating plants... very dangerous!
There are fossil fuels because things (like plants and animals) died hundreds of millions of years ago. Most Fossil fuels are non- renewable. Meaning they will not replenish untill we are dead and gone for hundreds of millions of years.
Millions of years
a fossil
its called a bobshed
Fossil fuels come from fossilized animals or plants and take millions of years to form so they are therefore "nonrenewable."
Because millions of years ago they were a lot bigger.
