COAL: Coal forms in swampy areas as the result of the decay of plants in the absence of oxygen. Biochemical changes produced by bacteria release oxygen and hydrogen and concentrate carbon. Coal goes through several changes during formation. With increased pressure and time, impurities and moisture are removed. In swamps where coal forms, other sediment, such as sand, clay, and silt, also is deposited. The weight of the sediment compresses the underlying organic matter. During this process, moisture and other materials are squeezed out, leaving a high carbon concentration.

OIL: Petroleum, or crude oil, and natural gas are important hydrocarbons that are found in nature within pores and fractures of rocks. Oil and gas form over millions of years as the result of the decay of marine organisms. These organisms die and collect on the ocean floor. Sediments such as clay and mud are deposited above these organisms. During burial and compaction, the organic matter becomes heated. Hydrocarbons are formed and are forced out of the source rock into permeable beds such as sandstone.

1. Coal is a power resource, fossil fuel and fund resource.

2. Coal used directly in industries and indirectly for pro­duction of thermal power.

3. Different by-products of coal are used in various in­dustries.

4. As a power resource, use of coal is decreasing.

5. Per unit heat and electricity generation from coal is less.

6. As coal hard and bulky, transport cost is high.

7. Cost of coal is less.

8. Extraction cost of coal is higher.

9. Probability of accident, during extraction of coal is more.

10. Coal emits smoke, ash and gas; pollutes environment.

11. For domestic lighting and room heating, coal is less used now.

12. Use of coal in railway and ship engines are decreas­ing.

13. Around coal mines host of industries developed. In­dustrial regions develop.

14. Nowadays, coal is less important in international trade.

15. Coal seldom influences world politics.


1. Petroleum is a power resource, fossil fuel and fund re­source.

Coal is made up of complex compounds of hydrogen,carbon and oxygen along with some free compounds of carbon ,nitrogen and sulphur.
It is a complex mixture of many hydrocarbons,water,salt,earth particles and other compounds of carbon,oxygen,nitrogen and sulphur.

Coal is formed after the decomposition of dead and decaying vegetation under high pressure and temperature over a million of years.
Petroleum is found in the earth's interiors formed by the a?cumulation of decomposition and deposition of sea organisms under high temperature and pressure in the absence of air.

Hope your doubt gets clarified.
