Archaeological Significance
0
Coal forms from the accumulation of plant debris in a swamp environment which is buried by sediments such as mud or sand and then compacted to form coal. 0

Learn more about Properties of Coal
What is Coal? In this section, we will learn more about properties of Coal i.e. physical and thermal properties. Physical properties of Coal include Color, Streak, Hardness, Structure, Cleavage, Fracture, Luster, Specific Gravity etc. The strength of Coal is Not Available. Streak of Coal is black while its cleavage is non-existent. Luster of Coal is dull to vitreous to submetallic and its fracture is conchoidal. Coal is opaque in nature.
