Coal - Formation, Types, Effect of Sulphur in Coal, Coal Distribution in World & India

Coal-  Also called as Black gold, second largest fuel source in global energy resources. Non-renewable sources, which include coal, oil and natural gas, have been the traditional sources of power for industry, transport and domestic users. Coal originates from the remains of trees, bushes. ferns, mosses, and other forms of plant life that flourished in  swamps and marshes millions of years ago. Important products are derived from coal by a process called pyrolysis-heating of coal in the absence of air which produces coke (a residue) and volatile matter such as coal gas, and a liquid known as coal tar.
Coal varies widely in important physical characteristics such as energy content, carbon percentage, moisture content, presence of contaminants such as sulfur, etc.
High-rank coals are high in carbon and therefore heat value, but low in hydrogen and oxygen. Low-rank coals are low in carbon but high in hydrogen and oxygen content.

Alexander's Invasion & its impact on Indian History

Alexander’s Invasion
  • He defeated the last king of the line of Darius, Xerexes in 333 BC and 331 BC. After! occupying the realm of the Persian king, Alexander crossed the Hindukush mountains in eastern Afghanistan in 327 BC.
  • He fought many tribes and took the city of Pushkalavati (near the junction of Swat and Kabul rivers) before crossing the river Indus in 326 BC.

For example, the famous Mahabharata battle known as Kurukshetra was fought between the Pandavas and Kauravas for territory. From the 6th century BC large territorial states known as Mahajanapadas (big kingdoms) emerged.
  • The 16 Mahajanpadas have been first listed in Buddhist literature Anguttar Nikaya.
