Coal, petroleum and natural gases are known as fossil fuels. Coal comes from the partly decayed remains of ancient plants that became buried millions of years ago and were subjected to great pressure. As these fossil fuels take time millions of years to form, the carbon in them tends to recycle very slowly. In as much as they take time to form, they are been used up rapidly.

On the other hand, light microscopes use visible light and magnifying lenses to examine specimens.
