Coal is a fossil fuel that we burn for fuel. We also use it in water and air purification systems, medical equipment, and as a building material. Describe how coal is formed, where it gets its original source of energy from, and why its distribution varies around the world. Then state whether coal is likely being formed today.

Coal is formed when dead plant matter decays into peat and is converted into coal by the heat and pressure of deep burial over millions of years.Steam coal, also known as thermal coal, is used in power stations to generate electricity. Coal is first milled to a fine powder, which increases the surface area and allows it to burn more quickly. ... The hot gases and heat energy produced converts water – in tubes lining the boiler – into steam.The presence of large coal deposits in regions that now have arctic or subarctic climates (such as Alaska and Siberia) is due to climatic changes and to the tectonic motion of crustal plates that moved ancient continental masses over Earth's surface, sometimes through subtropical and even tropical regions.

Explanation:

advantage of using stem cells in medical research:

1.       it provides medical benefits in the fields of therapeutic cloning and regenerative medicine.

2. it provides great potential for discovering treatments and cures to a variety of diseases including parkinson disease, spinal cord injuries, diabetes, alzheimer’s disease and many more.

3. limbs and organ could be grown in lab from stem cells and then used in transplant or treat illness.
